FT-IR spectra of polylysine/alginate membranes made with alginate containing various contents of mannuronic or guluronic acid residues have been recorded. The interpretation of the more important absorptions related to functional groups engaged in the complexes have been proposed and discussed using comparisons with spectra of cellulosic films and other published results. Mannuronnic rich alginate seemed to link stronger than guluronic rich alginate to the polylysine molecules which is illustrated by the continuum in absorption between 3000 cm-1 and 2000 cm-1. However, the analysis of the 2000-1000 cm-1 region prompted us to believe that the polymers were engaged in the same basic sort of molecular complexes. Therefore it is necessary that other parameters (either physical, as toughness, porosity, ...) other than variations in molecular structures are studied in order that the biological differences of the membranes may be explained.
已记录了由含有不同甘露糖醛酸或古洛糖醛酸残基含量的海藻酸盐制成的聚赖氨酸/海藻酸盐膜的傅里叶变换红外光谱。通过与纤维素膜光谱及其他已发表结果进行比较，对与参与复合物形成的官能团相关的更重要吸收峰进行了解释和讨论。富含甘露糖醛酸的海藻酸盐似乎比富含古洛糖醛酸的海藻酸盐与聚赖氨酸分子的连接更强，这一点由3000 cm-1至2000 cm-1之间吸收峰的连续性所表明。然而，对2000 - 1000 cm-1区域的分析使我们相信，这些聚合物参与了同一种基本类型的分子复合物。因此，有必要研究除分子结构变化之外的其他参数（如物理参数，如韧性、孔隙率等），以便解释膜的生物学差异。
