Abstract
In order to improve the mechanical properties of polylactic acid(PLA), PLA/MgAlCu-LDH/polyvinyl pyrrolidone(PVP) composite microsphere was successfully prepared on the basis of seminal emulson polymerization with PLA and PVP as monomer, MgAlCu-LDH as intercalating agent. Design-Expert 8.5 software was employed to optimize the processing technology with two steps. Firstly, single factor was analyzed based on the mass fraction ratio of MgAlCu-LDH to PLA, PVP concentration and stirring speed range being 1/15~1/8, 1~2%, 800~1200r/min, respectively. Secondly, the interaction effects of three factors were discussed according to the analysis of the software. The results show that the influence factors to microspheres size were as follows: the stirring speed > the mass fraction ratio of MgAlCu-LDH to PLA > PVP concentration. The optimized processing technology of microspheres indicates that the mass fraction ratio of MgAlCu-LDH to PLA is 1/15, the concentration of PVP is 2%, the stirring rate is 1200r/min. The structure and morphology of the dried frozen composite microsphere were characterized by XRD, FT-IR and SEM. The intercalation of part of the PLA into the gap of MgAlCu-LDH would be responsible for the new peaks on XRD spectra of MgAlCu-LDH and the disappear peaks at 1750cm-1, 1200cm-1 assigned to C=O on FT-IR spectra of PLA, which proves PLA/ MgAlCu-LDH/PVP composite microsphere was successfully prepared. Interestingly, some tinny channels resulted from volatile solvent on the surface of microsphere may be benefit for biocompatible.
