Shape Memory Corrosion-Resistant Polymeric Materials

Table 3

Types of fillers and their roles within the polymer matrix.

Filler type	Filler role
Fiber or fiber particulates	Increase mechanical properties but at the expense of shape memory abilities [21]
Silicon-carbon or silicon-oxide	Improve mechanical responsiveness, properties, and recovery times. Are most typically used due to their prevalence [5]
Carbon-based fillers	Enhances mechanical properties and converts energy, such as heat or electricity, to trigger shape memory effect [2, 4, 5]
Metals/metal oxides	Good mechanical properties, more conductive than carbon fillers, can achieve good biocompatibility in the nanoparticle form [5]
Cellulose	Biodegradable, can easily generate and break hydrogen bonds, allows for water-triggered shape memory responses [5]
