近年来，聚合物凝胶作为再生药物、软致动器和功能膜的支架材料引起了人们的广泛关注。这些应用需要坚韧和坚固的聚合物凝胶，如双网络凝胶所代表的。为了充分理解这一机制并开发出更先进的聚合物凝胶，我们需要充分理解传统聚合物凝胶的断裂能的分子起源，这是由固有的非均质性抑制的。本文给出了具有可控网络结构的模型聚合物凝胶的断裂实验结果，并讨论了聚合物凝胶的断裂机理。
Recently, polymer gels have drawn much attention as scaffolds for regenerative medicines, soft actuators, and functional membranes. These applications need tough and robust polymer gels as represented by the double network gels. To fully understand this mechanism and develop further advanced polymer gels, we need to fully understand the molecular origin of fracture energy for conventional polymer gels, which is inhibited by the inherent heterogeneity. In this paper, we show the experimental results on the fracture of model polymer gels with controlled network structure, and discuss the mechanism of the fracture of polymer gels.
