Bio-Based Disposable Containers for Food Services

Currently, petrochemical plastics dominate the food service industry due to their good mechanical properties and barrier against heat, water vapor, carbon dioxide, and oxygen. This widespread use is not only harmful to humans but also to the ecosystem as synthetic plastics disrupt ecological balance and deplete petroleum-based oil resources. Researchers and manufacturers are continuously addressing this problem by developing bio-based alternatives that provide numerous advantages including structural flexibility, biodegradability, and effective barrier properties. However, the high cost of production and unavailability of equipment for batch processing impede the potential for widespread manufacturing. Natural fibers mixed with bio-based adhesives derived from plants provide one of the biggest potential sources of bio-based materials for the food container industry. Not only does this address the issue of high raw material cost but it also has the potential to become sustainable once processing steps have been optimized. In this review, the current findings of several research related to the production of bio-based disposable food containers, packaging, and composites made from bio-based materials and bio-based adhesives are critically discussed. Several properties and characteristics important to the production of food service containers and primary packaging, as well as the existing challenges and future perspectives, are also highlighted.

Detection of Microdefects in Fabric with Multifarious Patterns and Colors Using Deep Convolutional Neural Network

Automatic detection of fabric defects is important in textile quality control, particularly in detecting fabrics with multifarious patterns and colors. This study proposes a fabric defect detection system for fabrics with complex patterns and colors. The proposed system comprises five convolutional layers designed to extract features from the original images effectively. In addition, three fully connected layers are designed to classify the fabric defects into four categories. Using this system, the detection accuracy is improved, and the depth of the model is shortened simultaneously. Optimal detection rates for testing dirty marks, clip marks, broken yams, and defect-free were 88.01%, 90.15%, 98.01%, and 97.73%, respectively. The experimental results show that the proposed method is effective, feasible, and has significant potential for fabric defect detection.

Mechanical Properties of Sandwiched Construction with Composite and Hybrid Core Structure

In the field of lighter substitute materials, sandwich plate models of composite and hybrid foam cores are used in this study. Three core structures: composite core structure and then the core is replaced by a structure of a closed and open repeating cellular pattern manufactured with 3D printing technology. It finally integrated both into one hybrid open-cell core filled with foam and employed the same device (WBW-100E) to conduct the three-point bending experiment. The test was conducted based on the international standard (ASTM-C 393-00) to perform the three-point bending investigation on the sandwich structure. Flexural test finding, with the hybrid polyurethane/polytropic acid (PUR/PLA) core, the ultimate bending load is increased by 127.7% compared to the open-cell structure core. In addition, the maximum deflection increased by 163.3%. The simulation results of three-point bending indicate that employing a hybrid combination of PUR-PLA led to an increase of 382.3%, and for PUR–TPU by 111.8%; however, the highest value recorded with PUR/PLA, which has the slightest stress error among the tests. Also, it is reported that when the volume fraction of reinforced aluminum particles is increased, the overall deformation becomes more sufficient, and the test accuracy improves; for example, rising from 0.5% to 3%, the midspan deflection of composite (foam-Al) is increased by 40.34%. There were noticeable improvements in mechanical properties in the 2.5% composite foam-Al.

Synthesis and Antibacterial Activity of Grafted Poly(Vinyl Chloride) Polymer against Gram-Positive and Gram-Negative Bacteria

Infectious diseases caused by microorganisms have gained worldwide attention in recent years. According to data compiled by the World Health Organization, the number of deaths resulting from infectious diseases is on the rise. In light of these dangers, the study of antibacterial materials has become increasingly vital. In this research, an antibacterial polymer was developed using poly(vinyl chloride) (PVC) and 4,4-diamminodiphenylmethane (DDM). The produced polymer’s chemical structure and thermal properties were investigated using Fourier-transform infrared spectroscopy, nuclear magnetic resonance, and thermo-gravimetric analysis. The antibacterial activity of the resulting PVC-g-DDM polymer was effective in killing both Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. The antimicrobial efficacy was tested using a spread plate method, demonstrating its potential utility in a variety of applications like biomedical, coatings, water purification systems, and others. Antimicrobial resistance is increasing, especially among bacteria that have acquired resistance to multiple therapeutics. To fully optimize and explore the polymer’s potential and its usage, more research is needed.

Design, Fabrication, and Characterization of 3D-Printed Multiphase Scaffolds Based on Triply Periodic Minimal Surfaces

The present work investigates the influence of material phases and their volume fractions on the elastic behavior of triply periodic minimal surface (TPMS) scaffolds for the potential modeling of bone scaffolds. A graphical tool using TPMS functions, namely Schwarz-D (diamond), gyroid, and modified gyroid, was developed and used to design and additively manufacture 3D multiphase scaffold models. A PolyJet, UV-cured 3D-printer system was used to fabricate the various TPMS scaffold models using three polymer materials with high, medium, and low stiffness properties. All TPMS models had the same volume fractions of the three polymer materials. Final models were printed into cylinders with a diameter of 20 mm and a height of 8 mm for mechanical testing. The models were subjected to compressive and shear testing using a dynamic mechanical analysis rheometer. All samples were tested at physiologically relevant temperature (37°C) to provide detailed structural characterizations. Microscopic imaging of 3D-printed scaffold longitudinal and cross sections revealed that additive manufacturing adequately recreated the TPMS functions, which created anisotropic materials with variable structures in the longitudinal and transverse directions. Mechanical testing showed that all three TPMS 3D-printed scaffold types exhibited significantly different shear and compressive properties (verifying anisotropic properties) despite being constructed of the same volume fractions of the three UV-printed polymer materials. The gyroid and diamond scaffolds demonstrated complex moduli values that ranged from 1.2 to 1.8 times greater than the modified gyroid scaffolds in both shear and compression. Control scaffolds printed from 100% of each of the three polymers had statistically similar mechanical properties, verifying isotropic properties.

Measurement Techniques and Methods for the Pressure Coefficient of Viscosity of Polymer Melts

Viscosity is a prominent rheological property of polymer, which is affected by temperature, pressure, shear rate, molecular structure, and other factors. Despite the importance of the pressure effect, there remains a paucity of investigations on the dependence of pressure on viscosity compared with other factors, such as shear rate and temperature. Previous research has established that the correlation between pressure and viscosity is usually expressed by the pressure coefficient. In this paper, different measurement techniques and methods for the pressure coefficient of viscosity of polymer melts are reviewed and evaluated on the basis of published experimental data. The capillary rheometer with a pressurized exit chamber is widely employed because of its accuracy and simple use. Besides, the accuracy and relationship of pressure coefficients determined by different methods are discussed.
