To prepare fully biodegradable materials, variable concentrations of luffa fiber (LF) namely 1, 3, and 5 phr, were incorporated into a poly(lactic acid) (PLA) matrix. To counteract the poor adhesion of the LF to PLA, a compatibilizer which is maleic anhydride‐grafted poly(lactic acid) has been incorporated and the properties of the composites with and without compatibilizer noted, respectively, PLA/LF...
In order to limit the hydrolytic degradation, recycled polyethylene terephthalate (rPET) was subjected to a heat treatment (annealing) to obtain treated rPET (trPET). To improve the mechanical properties of the latter, it was melt mixed with maleic anhydride grafted styrene ethylene/butylene–styrene copolymer (SEBS-g-MA) which acts as a toughening agent then compared to rPET and virgin PET (vPET)...
