New Nanocomposite Materials Dispersed with Poly(ethylene glycol):The Effects of Degradation and Mechanical Characteristics

摘要：

Nanocomposites of poly(lactic acid) (PLA) reinforcedwith cellulose whiskers highly dispersed with poly(ethyleneglycol) (PEG) were prepared for the first time. The compositesobtained by solvent casting methods from N, N-Dimethylacetamide(DMAc) were characterized by mechanicaltesting, fourier transform infrared spectroscopy (FT-IR), waterabsorption and biodegrade in simulated body fluid (SBF). Theresults showed that, by adding cellulose whiskers and dispersantsto the poly(lactic acid) (PLA) matrix, the water absorption andbiodegradation of the nanocomposites improved obviously. Thetensile strength and the elongation rate of the PLA/cellulosewhiskers/PEG composites was improved 20% and 6.7%. FT-IRanalysis showed that the compatibility among the PLA, cellulosewhiskers and PEG was good. The nanocomposites would be apotential tissue engineering implant in the clinical application,and the cellulose whiskers would be potential reinforcementnanofiller in the medical domain.
