Porous shape memory hybrids are fabricated with different matrix (silicone) hardness and different inclusion (polycaprolactone, PCL) ratios. They are characterized to obtain their mechanical response to cyclic loads (with/without pre-straining/programming) and their shape memory performances after body-temperature programming are investigated. These materials are lightweight due to their porous structures. Wetted hydrogels used in the fabrication process for creating pores are reusable and hence this process is eco-friendly. These porous shape memory hybrids exhibit the good shape memory effect of around 90% with higher inclusion (PCL) ratios, which is better than the solid versions reported in the literature. Hence, it is concluded that these materials have great potential to be used in, for instance, insoles and soles for comfort fitting, as demonstrated.
制备了具有不同基体（硅酮）硬度和不同内含物（聚己内酯，PCL）比例的多孔形状记忆复合材料。对其进行表征以获得它们对循环载荷（有/无预应变/编程）的力学响应，并研究了体温编程后的形状记忆性能。由于其多孔结构，这些材料重量轻。用于制造孔隙的湿水凝胶可重复使用，因此该过程是环保的。这些多孔形状记忆复合材料在较高内含物（PCL）比例下表现出约90%的良好形状记忆效应，这优于文献报道的实心版本。因此，可以得出结论，这些材料具有巨大的潜力，例如可用于鞋垫和鞋底以实现舒适贴合，如所示。
