英文摘要: By in-situ degradation of collagen fibers into gelatin under the thermal/mechanochemical effects of the extruder, PVA/gelatin composites were successfully prepared using PVA and collagen fibers derived from cattle hide limed split wastes as raw materials. The effect of extrusion temperature on the degradation of collagen fibers and the thermal processability and mechanical properties of the composites were studied. The results showed that the controllable degradation of collagen fibers in extruder could be realized by adjusting the extrusion temperature. Particularly, high extrusion temperature promoted the generation of low-molecular-weight gelatin and the esterification between the hydroxyl of PVA and the carboxyl of gelatin, as well as the hydrogen bonding between O-H, C = O, N-H in...
