利用可持续资源开发功能聚合物是一个越来越重要的追求。不饱和脂肪酸代表了用于此目的的一类潜在的令人感兴趣的可再生材料。它们的不饱和碳键允许交联形成固体聚合物。此外，它们的羧酸官能团提供了在所得聚合物内的特定表面化学的显示，并且还能够进行化学衍生。在这里，我们探讨了使用共轭亚油酸衍生的单体制造纳米尺度的尺寸选择性膜。钾盐共轭亚油酸表面活性剂（KCLA）在含甘油的水溶液中自组装形成六方填充圆柱体（HI）。这种结构提供了具有用于纳米过滤的水性连续通道的高度有序的介质。通过添加双官能共聚单体使Himmunase交联，并且在所得的薄聚合物膜（厚度< 400 nm）中以良好的保真度保留有序结构。这些膜有效地用作纳滤膜，对于带电溶质具有约1.2nm的尺寸截止，同时保持10.9 LMH/巴的高渗透性。这种性能与几种商业纳滤膜相当，因此这些材料对于在实际纳滤应用中推进可持续性问题具有潜在的意义。
The development of functional polymers using sustainable resources is an increasingly important pursuit. Unsaturated fatty acids represent a potentially interesting class of renewable materials for this purpose. Their unsaturated carbon bonds permit crosslinking to form solid polymers. Additionally, their carboxylic acid functional groups provide for the display of specific surface chemistry within the resulting polymers, and also enable chemical derivatization. Here, we explore the fabrication of nanometer-scale size-selective membranes using conjugated linoleic acid derived monomers. Potassium salt conjugated linoleic acid surfactants (KCLA) self-assembled to form hexagonally packed cylinders (HI) in an aqueous medium containing glycerol. This structure provides a highly ordered medium with aqueous-continuous channels for nanofiltration. The HImesophase was crosslinked with the addition of bifunctional comonomers and the ordered structure was retained with good fidelity in the resulting thin polymer films (< 400 nm thick). These film function effectively as nanofiltration membranes, with a size cut-off of approximately 1.2 nm for charged solutes, while maintaining a high permeance of ∼ 9 LMH/bar. This performance is on par with several commercial nanofiltration membranes and these materials are therefore of potential interest for advancing sustainability concerns in practical nanofiltration applications.
