Biomass-based polymeric materials have recently garnered a lot of attention from both academic and industrial realms, owing to their important roles for addressing environmental issues and achieving sustainable developments. As one of the cheapest and most widely available biomass feedstock, plant oils are promising to produce polymeric materials for replacing petroleum-based counterparts. However, there is lack of a green and highly effective method to prepare outstanding plant oil-based polymeric materials, limiting their potential applicability. In this work, surfactant-free RAFT-mediated emulsion polymerization was explored for the fabrication of plant oil-based ethanol aqueous adhesives. A series of plant oil-based ethanol aqueous adhesives have been successfully fabricated by introducing thymine-containing monomers to tackify the adhesives. The obtained ethanol aqueous adhesives showcase outstanding adhesive properties for distinct substrates and tunable adhesive performance upon UV irradiation. This work highlights that surfactant-free RAFT-mediated emulsion polymerization is a straightforward and feasible approach to fabricate prominent polymeric materials including adhesives or coatings from biomass feedstock such as plant oils.

通过无表面活性剂 RAFT 介导的乳液聚合制备的强紫外线响应植物油基乙醇水性粘合剂

由于生物质聚合物材料在解决环境问题和实现可持续发展方面的重要作用，它们最近引起了学术界和工业界的广泛关注。作为最便宜和最广泛可用的生物质原料之一，植物油有望生产用于替代石油基对应物的聚合物材料。然而，目前缺乏一种绿色高效的方法来制备优异的植物油基高分子材料，限制了其潜在的适用性。在这项工作中，探索了无表面活性剂的 RAFT 介导的乳液聚合，用于制备植物油基乙醇水性粘合剂。通过引入含胸腺嘧啶单体对粘合剂进行增粘，成功制备了一系列植物油基乙醇水性粘合剂。所获得的乙醇水性粘合剂对不同基材具有出色的粘合性能，并且在紫外线照射下具有可调的粘合性能。这项工作强调了无表面活性剂的 RAFT 介导的乳液聚合是一种直接且可行的方法，可以从植物油等生物质原料中制造突出的聚合物材料，包括粘合剂或涂层。
