Abstract

Herein, we describe a solvent-free bioinspired approach for the polymerization of ethylene brassylate. Artificial plant cell walls (APCWs) with an integrated enzyme were fabricated by self-assembly, using microcrystalline cellulose as the main structural component. The resulting APCW catalysts were tested in bulk reactions and reactive extrusion, leading to high monomer conversion and a molar mass of around 4 kDa. In addition, we discovered that APCW catalyzes the formation of large ethylene brassylate macrocycles. The enzymatic stability and efficiency of the APCW were investigated by recycling the catalyst both in bulk and reactive extrusion. The obtained poly(ethylene brassylate) was applied as a biobased and biodegradable hydrophobic paper coating.

摘要

在此，我们描述了一种用于聚乙交酯聚合的无溶剂仿生方法。以微晶纤维素为主要结构成分，通过自组装制备了集成酶的人工植物细胞壁（APCW）。将所得的APCW催化剂用于本体反应和反应挤出测试，单体转化率高，摩尔质量约为4 kDa。此外，我们发现APCW催化形成大型乙交酯大环化合物。通过在本体反应和反应挤出中循环使用催化剂，研究了APCW的酶稳定性和效率。所制得的聚乙交酯用作生物基可生物降解的疏水纸张涂层。
