论文摘要
水凝胶是广泛的软材料，可以提供广泛的应用。对凝胶的粘弹性特性的控制至关重要。正在进行的环境问题引起了消费者对使用更可持续的材料（包括水凝胶）的关注。但是，绿色材料是否与高功能兼容？在一种安全的设计方法中，这项工作表明，可以通过完全``可持续''成分，生物基的安培和生物聚合物（明胶，壳聚糖，壳聚糖和alginate和Alginate和Alginate和Alginate）来开发出具有外部刺激的原位弹性特性的功能水凝胶。生物学是一种通过微生物发酵获得的刺激性反应性糖脂，可以在高稀释液和刺激的快速变化的情况下自组装成纤维，也可以在水中自我组装成纤维或囊泡。可以通过温度或pH的平均值或pH值选择性地触发凝胶内糖脂和/或生物聚合物的相变，可以通过选择性触发糖脂的相变和/或生物聚合物的相变来调节生物学/生物聚合物互穿水凝胶的弹性特性。
Hydrogels are widespread soft materials, which can serve a wide range of applications. The control over the viscoelastic properties of the gel is of paramount importance. Ongoing environmental issues have raised the consumer's concern towards the use of more sustainable materials, including hydrogels. However, are greener materials compatible with high functionality? In a safe-by-design approach, this work demonstrates that functional hydrogels with in situ responsivity of their elastic properties by external stimuli can be developed from entirely ``sustainable'' components, a biobased amphiphile and biopolymers (gelatin, chitosan and alginate). The bioamphiphile is a stimuli-responsive glycolipid obtained by microbial fermentation, which can self-assemble into fibers, but also micelles or vesicles, in water under high dilution and by a rapid variation of the stimuli. The elastic properties of the bioamphiphile/biopolymer interpenetrated hydrogels can be modulated by selectively triggering the phase transition of the glycolipid and/or the biopolymer inside the gel by mean of temperature or pH.
