Ethyl cellulose (EC) membranes can be combined with efficient plasticizers derived from renewable resources to form supramolecular systems. In this paper, a novel ricinoleic acid-based sulfhydryl triol (STRA) was first synthesized and used as a plasticizer for EC membranes. A supramolecular membrane of EC and STRA using van der Waals forces was designed. The morphology, hydrophilic performance, thermal stability, and mechanical properties of the composites were investigated. While pure EC is brittle, its membrane ductility and hydrophilic performance can be improved by integration with STRA. The highest tensile strength was found in EC/STRA (90/10) (8.37MPa). Impressively, the EC/STRA(60/40) and EC/STRA(50/50) elongation at break values were 17.4 and 20.2 times higher, respectively, than that of pure EC. This novel ricinoleic acid-based sulfhydryl triol can be used as a feedstock for hydrophobic EC membranes.
乙基纤维素（EC）膜可以与源自可再生资源的高效增塑剂结合，形成超分子系统。本文首次合成了一种新型的蓖麻油酸基巯基三醇（STRA），并将其用作 EC 膜的增塑剂。利用范德华力设计了 EC 和 STRA 的超分子膜。研究了复合材料的形态、亲水性能、热稳定性和机械性能。纯 EC 是脆性的，但与 STRA 结合可以提高其膜的延展性和亲水性。在 EC/STRA（90/10）（8.37MPa）中发现了最高的拉伸强度。令人印象深刻的是，EC/STRA（60/40）和 EC/STRA（50/50）的断裂伸长率分别比纯 EC 高 17.4 和 20.2 倍。这种新型的蓖麻油酸基巯基三醇可用作疏水性 EC 膜的原料。
