摘要：

The photochemical stability of blends of collagen and poly(vinyl alcohol) has been studied by Fourier transform infrared spectroscopy (FTIR), UV-vis spectrophotometry, differential scanning calorimetry (DSC) and viscometry. Mechanical properties of the blends before and after UV irradiation were studied. Surface properties before and after UV irradiation were monitored using atomic force microscopy (AFM) and optical microscopy. The new materials obtained have different thermal, mechanical and photochemical stability than those of single components. They are more stable thermally and photochemically, but they have worse mechanical properties than pure collagen films. (C) 2003 Elsevier Ltd. All rights reserved.
