| Abstract: | PLA was grafted onto the surface of wollastonite surface,and PLA-g-wollastonite/PLA composite was prepared.The microstructure,mechanical properties and degradation properties of the composite were investigated.The results show that PLA-g-wollastonite improves the compatibility between the inorganic particles and PLA matrix,and makes the dispersion of the inorganic particles in PLA matrix more uniform;compared with wollastonite/PLA composite,the tensile property and flexural property of PLA-g-wollastonite/PLA composite are higher,the degradation speed is lower,and the mechanical properties during degradation are better. |
