Abstract

The biodegradable polylactide/poly(ethylene glycol) (PLA/PEG) hybrid membranes were fabricated via electrospinning of PLA/PEG solution. Their structures and properties were investigated by scanning electron microscopy, differential scanning calorimetry, and water contact angle. In vitro hydrolytic degradation showed that PEG content influenced the degradation rate of the PLA/PEG hybrid mats. The mechanical property was measured by tensile test and the result revealed that the addition of PEG had an obvious plasticization on PLA matrix. In-vitro biocompatibility was investigated by culturing cell on the scaffolds and MTT assay. The results indicated that the cell could attach and proliferate on the membranes, so confirmed that the PLA/PEG hybrid membrane had good biocompatibility, and it could be a promising biomaterial for tissue engineering applications. © 2011 Wiley Periodicals, Inc.
