使用微胶囊化和直接吸附法两种方式将相变材料与水泥结合分别制成了含相变微胶囊水泥基复合建材及含相变材料水泥基复合建材,搭建实验测试系统,对复合建材的调温储能特性进行了测试。微胶囊化相变材料和纯相变材料的加入对水泥基建材的微观结构形貌具有较为明显的影响。热重曲线显示纯水泥、相变微胶囊-水泥、相变材料-水泥试样的失重率依次增加,相变微胶囊-水泥式样的稳定性最好;复合成分所占质量分数相同时,相变材料-水泥试块强度略低于相变微胶囊-水泥试块;调温测试表明,在水泥中添加相变微胶囊颗粒或纯相变材料时均具有一定的调温储能功能,能明显减缓水泥基建材的温度在相变温度附近的波动;尽管直接吸附法制备的相变材料-水泥复合建材具有较好的调温性能,但其可循环性较差,伴有刺激性气味逸出,实用性较差。因此相变微胶囊-水泥复合较适宜作为新型建材推广使用。

通过在植入材料表面构建仿生微纳结构,可以为机体细胞提供有利的微环境,从而提高细胞活性并促进组织修复。然而,到目前为止仍没有一种有效的骨组织工程材料能在成分和结构上同时模拟天然骨。因此,采用仿生矿化法复合微纳制造技术在仿生骨修复材料中构建了大规模可控的微纳结构,并且首次在体内证明了该材料的成分和可控有序的微纳结构能够长效促进血管化骨再生。研究结果表明:首先,通过复合高分子模板实现对仿生矿化羟基磷灰石纳米颗粒(HANPs)形貌的调控,而且微接触法将有序的微米图案大规模地整合入骨组织工程材料中;其次,大鼠间充质干细胞(r MSCs)在该仿生骨组织工程材料表面表现出高度取向生长,其成血管分化和成骨分化表达增加;同时,构建的大鼠颅骨缺损模型也证明了该仿生骨组织工程材料能促进血管化膜内成骨。这为控制干细胞定向分化提供了一种先进的研究平台,并为构建基于仿生微纳结构的新型仿生骨组织工程材料提供了有力的理论基础和实际依据,具有潜在的临床应用价值。
