title: Carboxymethyl chitin/organic rectorite composites based nanofibrous mats and their cell compatibility.
abstract: In this study, carboxymethyl chitin (CMC) - organic rectorite (OREC)/poly (vinyl alcohol) (PVA) composite nanofibrous mats were successfully prepared via electrospinning. SAXRD pattern showed that the interlayer distance of OREC was increased from 3.68 to 4.08nm, which verified that polymer chains were intercalated into the interlayer of OREC. Field emission scanning electron microscopy, Fourier transform infrared spectra and energy-dispersive X-ray spectroscopy were used to characterize the morphology and microcosmic structure of nanofibrous mats. Thermal properties of mats were determined by differential scanning calorimetry. To evaluate the cell compatibility of mats, mouse lung fibroblast (L929) was chosen for cell attachment and spreading assay. The results shows that nanofibrous mats contained OREC have better thermal properties. Besides, the addition of OREC has little effect on the cell compatibility of nanofibrous mats.
