Effect of benzoylation treatment on various biofibers.

S. no.	Fibers used	Type of chemical treatment	Effects	Ref.
1	Sisal	Benzoylation treatment	Improvement in tensile strength by 91%.	[75]
2	Jute	Benzoylation treatment	Improvement in storage modulus and thermal stability.	[150]
3	Flax	Benzoylation treatment	The treated composites were found to have highest tensile and impact strength for LDPE and highest impact strength for HDPE. Resulted in less water absorption as compared to silane and peroxide. Smooth fiber surface was observed.	[43]
4	Sisal	Benzoylation treatment	At 6% of benzoyl peroxide showed better mechanical properties.	[83]
5	Banana	Benzoylation treatment	The treatment significantly improved thermal conductivity and was found to have increase in tensile strength and modulus by 13% and 5%, respectively, although not as good as alkali and silane-treated fiber.	[109]
6	Sisal	Benzoylation treatment	The treatment increased the activation energy for glass transition temperature (Tg). Maximum activation energy was observed.	[151]
