介绍了壳聚糖碘膜制剂的制备方法及其影响因素。通过物理化学方法，研究了壳聚糖碘结构，实验结果表明，壳聚糖吸附碘量受浸渍液中碘浓度，乙醇浓度和浸渍时间的影响。壳聚糖吸附碘后，壳聚糖和碘间发生了结构变化，生成了壳聚糖碘无定型复合物。
The preparation method of chitosan iodine membrane preparation and its influencing factors were introduced. The structure of chitosan iodine was studied by physicochemical method. The experimental results showed that the amount of iodine adsorbed by chitosan was affected by the concentration of iodine in the immersing solution, the concentration of ethanol and the impregnation time. Chitosan adsorbed iodine, chitosan and iodine structural changes occurred, resulting in chitosan iodine amorphous complex.
