Abstract

The effect of a natural biocide based on forest chemical raw materials as an additive to cellulose acetate (CA) casting solutions on the structure and properties of the resulting membranes was studied. The NMR method was used to determine the component composition of rosin and turpentine, from which rosin terpene maleic adduct (RTMA) was obtained. Successful modification of the AC-membranes was confirmed by the results of FTIR-spectroscopy. The operational properties of AC-membranes were studied (electron microscopy, atomic force microscopy, study of the transport properties of membranes). It was shown that the introduction of 1.5–2.0 wt % RTMA into the casting solutions does not affect the transport properties of the membranes, but decrease the surface roughness of the selective layer. At the same time, modified membranes are characterized by increased antibacterial resistance and resistance to fungal fouling.

林化原料中杀菌剂改性醋酸纤维素膜的结构与性能

研究了以林化原料为原料的天然杀菌剂添加到醋酸纤维素（CA）铸造液中对膜结构和性能的影响。采用核磁共振法测定松香和松节油的组分组成，得到松香萜烯马来烯加合物（RTMA）。红外光谱分析结果证实了活性炭膜改性的成功。研究了交流膜的操作性质（电子显微镜、原子力显微镜、膜的输运性质研究）。结果表明，加入1.5 ~ 2.0 wt %的RTMA对膜的输运性能没有影响，但降低了选择层的表面粗糙度。同时，改性膜具有增强的抗菌性和抗真菌污染能力。
