| Abstract: | A novel method of grafting ring-opening polymerization of DL-lactide(DLLA)onto the surface of wollastonite particles was developed.PDLLA was directly connected onto the wollastonite surface through a chemical linkage.The PDLLA-g-wollastonite particles could be stably dispersed in organic solvent such as ethanol for several days.Fourier transformation infrared(FTIR)spectra confirmed the existence of PDLLA on the surface of PDLLA-g-wollastonite.The maximum graft degree of PDLLA on the wollastonite paticles de... |
