1. 研究目的与意义（文献综述）
1.1 目的及意义
水凝胶是一种经适度交联而具有三维网络的、亲水但不溶于水的功能高分子材料[1]。智能水凝胶[2-4]，又称刺激响应水凝胶，是一类能对外界环境变化具有响应性的水凝胶，其在外界环境刺激因素（包括温度[5-7]、光[8-10]、电磁场[11-13]和溶剂[14; 15]等）影响下，能产生有效响应，使自身的性质（如相态、形状、力学性能[16]等）随之发生变化，如图1（a）、（b）、（c）所示为智能响应性水凝胶实现跨结构尺度变化。
近年来，基于响应性水凝胶材料的各种功能性器件在智能微机械[17-19]、软体机器人[20-22]及生物医学等领域广泛应用。将刺激响应性水凝胶材料同惰性材料相结合，控制不同材料按照特定的图案进行排布，在外界环境刺激下，水凝胶材料会响应环境刺激溶胀或收缩，而惰性材料保持不变，这种复合结构就能够按照设定的图案进行响应性形变。按照这一思路，各种水凝胶自折叠致动器结构[23-25]、折纸结构[26-28]被不断报道，如图2（a）、（b）所示为响应性水凝胶致动器的应用。
2. 研究的基本内容与方案
2.1 研究（设计）的基本内容
1）根据文献调研响应性水凝胶的研究现状，详细了解响应性水凝胶的工作原理和应用形式，对掺杂纳米材料和多响应机制深入理解。
2）激光修饰衬底薄膜工艺的研究。通过激光修饰衬底材料将其制作为所需要的形状。激光剪裁工艺需要考虑薄膜的厚度、物理性质，以及对热量的吸收程度，为之相关的是激光参数，包括激光波长、重复频率、激光功率和脉冲宽度。
