The present work describes the development of sustainable bio‐benzoxazines for oil water separation and its composites for applications where a low dielectric constant is required. In addition, cardanol benzoxazine monomers (C‐ida and C‐pyta) with low curing temperature were designed with inbuilt catalytic core using two different heterocyclic amines, namely tetra aryl imidazole diamine (ida) and pyridine core triamine (pyta). Cotton fabric coated with poly(C‐ida) and poly(C‐pyta) show water contact angle values of 160° and 164°, respectively. The oil‐water separation efficiency of the polybenzoxazines coated cotton fabrics was 95%. Further, the poly(C‐ida) and poly(C‐pyta) matrices were reinforced with varying weight percentages (1, 3, 5, 7, and 10 wt%) of glycidylpropoxytrimethylsilane‐functionalized biosilica. The benzoxazine matrices and composites obtained were characterized using different analytical techniques in order to assess their molecular structure, cure behavior, thermal stability, morphology, surface, and dielectric behavior. Data obtained from different studies suggest that these matrices and composites can be used as coatings for oil‐water separation and high‐performance micro‐electronics insulation applications under adverse environmental conditions.

杂环胺基腰果酚-苯并恶嗪用于油水分离的研究

本工作描述了用于油水分离的可持续生物苯并恶嗪的开发及其在要求低介电常数的应用中的复合材料。此外,还设计了具有较低固化温度的腰果酚苯并恶嗪单体(C-ida和C-pyta),并使用两种不同的杂环胺(即四芳基咪唑二胺(ida)和吡啶核心三胺(pyta))内置催化核。涂有聚(C-ida)和聚(C-pyta)的棉织物的水接触角分别为160°和164°。聚苯并恶嗪涂层棉织物的油水分离效率为95%。此外,聚(C-ida)和聚(C-pyta)基质通过不同重量百分比(分别为1、3、5、7、10 wt%)的缩水甘油基丙氧基三甲基硅烷官能化的生物二氧化硅增强。为了评估其分子结构,固化行为,热稳定性,形态,表面和介电性能,使用不同的分析技术对所得苯并恶嗪基体和复合材料进行了表征。从不同研究获得的数据表明,在不利的环境条件下,这些基质和复合材料可用作油水分离和高性能微电子绝缘应用的涂料。
