Acrylamide-2-hydroxyethyl methaacrylate (AAm-HEMA) copolymer was used for covalent coupling of Horseradish peroxidase (HRP). Hydroxyl and amino groups were activated using glutaraldehyde and p-benzoquinone, respectively, before coupling of the enzyme. Activation of both amino and hydroxyl groups gave a...
中国科学院宁波材料所付俊研究员团队报道了一种基于高强度导电水凝胶的线性高灵敏度应变传感器。该导电凝胶由柔性的丙烯酰胺-甲基丙烯酸羟乙酯共聚物与原位生成的刚性聚苯胺组成半互穿网络水凝胶,其中P(AAm-co-HEMA)与PANI之间依靠氢键作用实现柔性绝缘网络与刚性导电网络之间的紧密结合。基于这样的互穿网络结构,聚苯胺在该...
