我们报告了一种新的和强大的战略，以发展高性能的压敏粘合剂（PSA）的化学品直接从原料生物质解构。这项工作的一个特别独特和可转化的方面是使用从真实的生物质获得的单体，而不是模型化合物或木质素模拟物，以产生明确定义的和纳米结构形成的聚合物。本文中，白杨解聚，然后进行最小的纯化步骤（过滤和萃取），以高纯度和产率产生两种芳香族化合物，4-丙基姜油酚和4-丙基愈创木酚。这些芳香族化合物与丙烯酸酯或甲基丙烯酸酯基团的有效官能化产生了可以通过可扩展的可逆加成-断裂链转移（RAFT）过程容易地聚合的单体，以产生具有高玻璃化转变温度和稳健的热稳定性的聚合物材料，特别是相对于其他潜在的生物基替代品。这些木质素衍生的化合物用作由丙烯酸4-丙基辛二醇酯和丙烯酸正丁酯（也可以是生物基的）组成的低分散性三嵌段聚合物中的主要组分。所得PSA在不添加任何增粘剂或增塑剂的情况下对不锈钢表现出优异的粘附性。180°剥离力高达4 N cm-1，粘着力高达2.5 N cm-1，与商业Fisherbrand标签胶带和Scotch Magic胶带竞争，证明了我们的生物质衍生材料的实际意义。我们展示了成功地将直接从原始生物质解构中获得的材料并入用于胶带的纳米结构压敏粘合剂的开发中。
We report a new and robust strategy toward the development of high-performance pressure sensitive adhesives (PSAs) from chemicals directly obtained from raw biomass deconstruction. A particularly unique and translatable aspect of this work was the use of a monomer obtained from real biomass, as opposed to a model compound or lignin-mimic, to generate well-defined and nanostructure-forming polymers. Herein, poplar wood depolymerization followed by minimal purification steps (filtration and extraction) produced two aromatic compounds, 4-propylsyringol and 4-propylguaiacol, with high purity and yield. Efficient functionalization of those aromatic compounds with either acrylate or methacrylate groups generated monomers that could be easily polymerized by a scalable reversible addition–fragmentation chain-transfer (RAFT) process to yield polymeric materials with high glass transition temperatures and robust thermal stabilities, especially relative to other potentially biobased alternatives. These lignin-derived compounds were used as a major component in low-dispersity triblock polymers composed of 4-propylsyringyl acrylate and n-butyl acrylate (also can be biobased). The resulting PSAs exhibited excellent adhesion to stainless steel without the addition of any tackifier or plasticizer. The 180° peel forces were up to 4 N cm–1, and tack forces were up to 2.5 N cm–1, competitive with commercial Fisherbrand labeling tape and Scotch Magic tape, demonstrating the practical significance of our biomass-derived materials. We demonstrated the successful incorporation of materials obtained directly from raw biomass deconstruction in the development of nanostructured pressure sensitive adhesives for use in tapes.
