Abstract Microspheres with phase change properties were fabricated by polymerization of hexadecyl acrylate (HA) and different cross-linking agents. The samples were characterized by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA). The results show that, the samples that added cross-linking agents have a smooth surface and the latent heat of them is different. The experiments show that all of the cross-linked copolymer shells can be made into temperature controlled release microspheres. These materials can be potentially applied in the field of thermal energy storage. β-tricalcium phosphate was encapsulated in microspheres to obtain one with a fast release effect. It will effectively promote bone conduction when these microspheres were implanted into a bone defect. This microsphere can be used for orthopedic implant or coating of instrument in the future.

丙烯酸十六烷基酯交联相变微球的制备与表征

摘要 通过丙烯酸十六烷基酯(HA)和不同的交联剂聚合制备了具有相变特性的微球。通过扫描电子显微镜(SEM)、傅里叶变换红外光谱(FTIR)、热重分析(TGA)对样品进行表征。结果表明,加入交联剂的样品表面光滑,潜热不同。实验表明,所有的交联共聚物壳都可以制成温控释放微球。这些材料可潜在地应用于热能储存领域。β-磷酸三钙被包裹在微球中以获得具有快速释放效果的微球。当这些微球植入骨缺损处时,将有效促进骨传导。
