摘要

本文报道了一种具有温度和pH响应的智能聚合丙烯酸鞣剂(合成鞣材料)的合成和应用，研究了该聚合物在室温(28℃)下不同pH值(1-10)下的行为。还确定了与胶原蛋白的相互作用，以了解聚合物对胶原蛋白二级结构的反应。使用实验合成鞣剂制成的皮革在人工模拟下加热时，与对照合成鞣剂处理的皮革(1±0.5°C)相比，耐温性更高，为3±0.5°C。实验皮革表现出较好的强度和感官性能。这些聪明的皮革发现它的应用在极端气候条件下的热或冷。

Thermal Sensitive Agents for Making Stimuli Responsive Leathers

Herein, we report the synthesis and application of a smart polymeric acrylic syntan (synthetic tanning material), which can respond to temperature and pH. Behavior of polymer at different pH (1-10) at room temperature (28°C) was studied. Also interactions with collagen were ascertained in order to understand the polymers’ response towards secondary structures of collagen. Leather made using the experimental syntan demonstrated higher temperature resistance of 3±0.5°C compared to control syntan treated leathers (1±0.5°C) when exposed to heat under artificial simulation. Experimental leathers exhibited better strength and organoleptic properties. These smart leathers find its application in extreme climatic conditions of heat or cold.
