This article deals with an natural collagen blended with chitosan, poly(vinyl alcohol)(PVA). We investigated the swelling properties of collagen and collagen complex in the solution with different pH, and the swelling/deswelling behavior of collagen and collagen-chitosan complex when changing the pH of the medium from 5.4 to 1.8 and in the reverse. The results show that the swelling degree of collagen and collagen complex are dependent to pH of the solution, and the swelling behavior of collagen and collagen-chitosan complex are pH-responsive.
本文研究了一种与壳聚糖、聚乙烯醇（PVA）混合的天然胶原蛋白。我们研究了胶原蛋白及胶原蛋白复合物在不同pH值溶液中的溶胀特性，以及当介质pH值从5.4变为1.8再变回时胶原蛋白和胶原蛋白-壳聚糖复合物的溶胀/消溶胀行为。结果表明，胶原蛋白及胶原蛋白复合物的溶胀程度取决于溶液的pH值，且胶原蛋白和胶原蛋白-壳聚糖复合物的溶胀行为具有pH响应性。
