热塑性硫化胶形状记忆材料综合实验教学改革

Reform on Comprehensive Experimental Teaching of Shape Memory Materials Based on Novel Thermoplastic Vulcanizates

通过热塑性硫化胶的形状记忆材料综合实验,让大学生系统地实践材料合成与制备—材料成形加工—材料结构表征—材料性能测试,掌握橡胶的配合与混炼、动态硫化、热塑性硫化胶的模压成形、多相体系微观结构的表征、形状记忆材料的性能表征等基本实验技能,提高大学生运用理论知识解决实践问题的能力。该综合实验课的教学内容对于学生深入理解橡胶混炼、橡塑体系的动态硫化、多相体系微观结构的观察、力学性能及热致型形状记忆材料的性能表征具有重要意义,并且有助于大学生的实践能力及创新能力的养成。

The undergraduates could practice the materials synthesis and preparation, materials processing,microstructure characterization and the properties testing of materials by the comprehensive experiment of shape memory materials based on novel thermoplastic vulcanizates. Moreover,the undergraduates could master the basic experimental skills of the rubber composition formula,the mixing of rubber preblend,the dynamic vulcanization method,the molding of thermoplastic vulcanizate,the microstructure characterization of the multiphase blends,and the characterization of the shape memory behavior of the prepared thermoplastic vulcanizates. The comprehensive experimental teaching could stimulate the ability to apply the theoretical knowledge to solve the practical problems. The experimental course is of great significance for the undergraduates to in-depth understand the mixing principle of rubber preblend,the dynamic vulcanization of thermoplastic resin and rubber preblend,the characterization of microstructures of the prepared blends,the mechanical property and the shape memory behavior of the prepared thermoplastic vulcanizates;furthermore,it could help the undergraduates to cultivate the practical and innovative ability.
