| Abstract: | This study examined the interfacial adhesion, mechanical, and thermal properties of compatibilizing agent-treated and non-treated
biocomposites as a function of the type of compatibilizing agent. The tensile strength, interfacial adhesion, and heat deflection
temperature (HDT) of maleic anhydride-grafted poly(butylene succinate) (PBS-MA) and maleic anhydride-grafted poly(lactic acid)
(PLA-MA)-treated biocomposites are greater than those of untreated maleic anhydride-grafted poly(styrene-b-ethylene-co-butylene-b-styrene)
triblock copolymer (SEBS-MA) and maleic anhydride-grafted polypropylene (MAPP)-treated biocomposites. The storage modulus
(E′) values and the tan δmax temperatures (T
g) of PBS-MA and PLA-MA-treated biocomposites were slightly higher than that of the untreated biocomposites. |
