Abstract

The behavior of a biodegradable CO2 -based polymer polypropylene carbonate (PPC) as polymer matrix of wood fi ber (WF) composites was examined and compared with that of using poly(lactic acid) (PLA) as the matrix. The PPC/WF composites displayed poor mechanical properties as compared to PLA/WF composites because PPC is an amorphous polymer with low Tg and poor thermal stability. However, when PPC was used in conjunction with PLA in WF composites, the mechanical strength and modulus of the composites could match or even exceed the level of PLA/WF composites. The strong intermolecular interactions between PPC and WF and those between PPC and PLA enhanced the bonding between compatible PPC/PLA matrix and WF fi llers, resulting in improved fl exural strength and modulus over a broader temperature range that reduced the impact of the low Tg effect of PPC. The crystalline structures of PLA were also modifi ed in the PPC-PLA/WF composites, while the thermal stability of the composites was improved.
