Intelligent materials have the ability to sense the environment and respond to their surrounding accordingly. Herein, the thermally conductive hybrid films were intellectualized by using activated shape memory composite as matrix, which endows hybrid films with active heat dissipation behavior. The obtained hybrid films not only visualize the temperature of the device by the change of shape, but also further improve thermal management abilities through the increase of contact area of the films with air in the shape changing process. The hybrid films also show high thermal conductivity because the multilayered structure was designed and constructed through the method of evaporation-induced self-assembly followed by hot-pressing technology. With the same content of graphene nanosheets, thermal conductivities of hybrid films are increased with the increase of layers. Five layered hybrid film shows the highest thermal management abilities and achieves the thermal conductivity as high as 19.37 W·m⁻¹·K⁻¹, which is 79.4% higher than single layered hybrid film. The structure design of hybrid films and their intellectualization opens up a new direction to improve thermal management effect of soft polymeric materials.

智能材料具有感知环境并相应地响应周围环境的能力。本文以活性形状记忆复合材料为基质对导热杂化薄膜进行了智能化，赋予杂化薄膜以主动的散热性能。所得的杂化膜不仅通过形状变化可视化装置的温度，而且通过在形状变化过程中增加膜与空气的接触面积来进一步提高热管理能力。杂化膜还显示出高导热性，因为通过蒸发诱导自组装和热压技术设计和构造了多层结构。使用相同含量的石墨烯纳米片，杂化膜的热导率随层数的增加而增加。五层混合膜显示出最高的热管理能力，并实现了高达19.37 W·m的导热率^-1 ·K ^-1，比单层混合膜高79.4％。杂化膜的结构设计及其智能化为改善软质高分子材料的热管理效果开辟了新的方向。
