Abstract

Heteropolymeric materials of resorcinol, aniline, urea, and formaldehyde are synthesized by 1:1:1:3 molar ratios of the respective monomers with different percentages of hydrophilic bentonite via a mixed condensation polymerization in an aqueous acidic media. The heteropolymeric material and heteropolymeric/hydrophilic bentonite were characterized by Fourier transform FT-IR spectroscopy and UV–Vis absorption spectra. The surface morphology of heteropolymer composites was recorded at various magnification powers by SEM which revealed well-defined granular spherical morphology of variable size in the range of 0.220 μm to 1.370 μm. Moreover, small pieces of bentonite were inserted and distributed through the field with different particle sizes. They cumulated and condensed in certain zones forming some plaques of different sizes. The heteropolymeric material is soluble in most of the organic solvents including, THF, DMF, and DMSO. It is also dissolved in concentrated HNO₃. The new synthesized heteropolymeric material was examined as an antimicrobial agent. The current procedure introduces an inexpensive and eco-friendly approach for developing new heteropolymer composites acquiring the requested new functionality.

新型杂聚物复合材料的环保合成及其抗菌性能

摘要

间苯二酚，苯胺，尿素和甲醛的杂聚合材料是通过在含水酸性介质中通过混合缩聚反应以具有不同百分比的亲水性膨润土的各单体的摩尔比为1：1：1：3来合成的。通过傅立叶变换FT-IR光谱和UV-Vis吸收光谱对杂聚物材料和杂聚物/亲水性膨润土进行了表征。通过SEM以不同的放大倍数记录了杂聚物复合材料的表面形态，该形态揭示了明确定义的，尺寸可变的颗粒球形形态，其范围为0.220μm至1.370μm。此外，插入了小块膨润土并以不同的粒径分布在整个田野中。它们在某些区域累积并凝结，形成一些大小不同的斑块。杂聚物材料可溶于大多数有机溶剂，包括THF，DMF和DMSO。它也溶解在浓HNO _3中。研究了新合成的杂聚物材料作为抗微生物剂。当前的程序引入了一种廉价且环保的方法，用于开发获得所需新功能的新型杂聚物复合材料。
