Membranes produced by crosslinking chitosan with magnesium phytate were prepared using highly deacetylated chitosan and its -carboxymethyl, -carboxymethyl and ,-carboxymethyl derivatives. The conditions of the membrane production were described. IR, Raman, electron absorption and emission spectra were measured and analyzed for all the substrates. It was found that -carboxymethyl chitosan derivative is the most effectively crosslinked by magnesium phytate, and the films formed on this substrate exhibit good mechanical parameters of strength, resistance and stability. Strong O-H···O hydrogen bonds proved to be responsible for an effective crosslinking process. Newly discovered membrane types produced from chitosan and magnesium phytate were characterized as morphologically homogenous and uniform by scanning electron microscopy (SEM) and IR measurements. Due to their good covering properties, they do not have pores or channels and are proposed as packaging materials.
使用高度脱乙酰化壳聚糖及其 - 羧甲基、 - 羧甲基和 , - 羧甲基衍生物制备了通过壳聚糖与植酸镁交联产生的膜。描述了膜的制备条件。对所有底物测量并分析了红外光谱、拉曼光谱、电子吸收光谱和发射光谱。发现 - 羧甲基壳聚糖衍生物最有效地被植酸镁交联，并且在该底物上形成的膜表现出良好的强度、抗性和稳定性等机械参数。强O-H···O氢键被证明是有效交联过程的原因。通过扫描电子显微镜（SEM）和红外测量，新发现的由壳聚糖和植酸镁制成的膜类型在形态上被表征为均匀一致。由于它们具有良好的覆盖性能，没有孔隙或通道，因此被提议作为包装材料。
