Mechanical Properties of Polyhydroxyalkanoate Bioceramic Nanocomposites

摘要

New composites prepared containing nanoscale hydroxyapatite or monetite uniformly distributed in a polyhydroxyalkanoate (polyhydroxybutyrate or polyhydroxybutyrate-hydroxyvalerate) matrix with mass fractions of 1%5% were then injected into dumb-like specimens. The results show that the tensile strength and the tensile modulus of the composites are improved. The microstructures of the composites were observed using transmission electron microscopy (TEM).
