Sustainable functional materials derived from renewable biomass provide momentum for the communities of polymer science. We report a supramolecular approach to the preparation of strong biobased polymer nanocomposites with stimuli-responsive behaviors using soybean oil (SO) and cellulose nanocrystals (CNCs). SO-derived polymers were modified with hydroxyl −OH and carboxyl −COOH groups via thiol–ene click chemistry, facilitating hydrogen-bonding interactions with CNCs to improve the overall compatibility in the nanocomposites. These nanocomposites exhibited high tensile strength and maintained high storage modulus up to 200 °C. Moreover, these nanocomposites showed a fast and reversible mechanical response to water, an external stimulus to tune intermolecular hydrogen bonding.

源自植物油和纤维素纳米晶体的超分子聚合物纳米复合材料

源自可再生生物质的可持续功能材料为聚合物科学界提供了动力。我们报告了一种超分子方法，以使用大豆油（SO）和纤维素纳米晶体（CNCs）制备具有刺激响应行为的强生物基聚合物纳米复合材料。SO衍生的聚合物通过硫醇-烯点击化学方法被羟基-OH和羧基-COOH基团改性，促进了与CNCs的氢键相互作用，从而改善了纳米复合材料的整体相容性。这些纳米复合材料显示出高拉伸强度，并保持了高达200°C的高储能模量。此外，这些纳米复合材料显示出对水的快速和可逆的机械响应，水是一种外部刺激，可调节分子间的氢键。
