我们报道了一种通过简单的混合方法制备的新型橡胶薄膜，它实现了在41°C的临界温度下与水的接触角的陡峭的温度依赖关系。我们将普通SBR与已知的温度响应性PNIPA混合制成温度响应性橡胶。该胶膜的表面润湿性在41℃以下的亲水性和41℃以上的疏水性之间有明显的切换，这种切换特性可能与PNIPA和SBR的混合比例、制备方法、添加的化学物质等因素有关。这种混合技术将用于控制各种SBR类橡胶材料的表面温度润湿性能，如汽车轮胎在雨天的湿制动性能。
We report a novel rubber film made by a simple mixing method, which realizes a steep temperature dependence of the contact angle of water at a critical temperature of 41°C. We mixed a common SBR with a known temperature-responsive PNIPA to make a thermo-responsive rubber. This rubber film distinctly showed a switch of surface wettability between hydrophilic below 41°C and hydrophobic above 41°C. The switching property is possibly controlled by the mixing ratio of PNIPA to SBR, preparation method, added chemicals, and so on. This mixing technique will be applied for the control of surface wetting properties by temperature on various SBR-like rubber materials, such as wet-brake performance of automobile tires on a rainy day.
