互穿聚合物网络（IPN）以一锅法蓝光活化方案形成，其中CuAAC和甲基丙烯酸酯反应的逐步和链生长聚合分别同时触发但顺序进行。玻璃态IPN在环境条件下聚合，并且由于其显著增强的韧性而能够在失效前承受高应变。此外，这种材料表现出形状记忆属性，在高温下具有容易调节的机械性能。IPN在蓝光下以一锅法快速生成，形成玻璃状和透明的材料。IPN表现出高韧性和形状记忆属性。
An interpenetrating polymeric network (IPN) is formed in a one-pot blue-light activated scheme, where the step- and chain- growth polymerizations of the CuAAC and methacrylate reactions, respectively, are simultaneously triggered but proceed sequentially. The glassy IPN is polymerized under ambient conditions and is able to withstand high strain before failure owing to its significantly enhanced toughness. Additionally, this material exhibits shape memory attributes with readily tunable mechanical properties at high temperature. An IPN is generated rapidly under blue-light in a one-pot scheme, forming a glassy and transparent material. The IPN exhibits high toughness and shape memory attributes.
