Abstract To clarify the effects of lignin as a biodegradable filler added into the
PLA matrix, PLA/lignin composites with or without silane coupling agent of γ-
(2,3-epoxypropoxy)propy trimethoxysilane (KH560) were prepared by a one-step
solvent-free modification method. The effects of KH560 as a compatibilizer on
the morphology, chemical structure, crystallization behavior, thermal degradative
behavior as well as mechanical strength of the PLA/lignin composites were analyzed in detail. It was found that, after modification by KH560, the fractured surfaces of composites became smooth, suggested sufficient bonding between the
lignin and PLA in the composites with KH560 coupling… More >
