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… More >
