The invention provides a multifunctional PTC (Positive Temperature Coefficient) graphene heating skin and a preparation method thereof, and belongs to the technical field of light-transmitting coating veneers in automotive interiors. Comprising a surface layer, a pattern layer, an electrode layer, a graphene heating layer, a capacitive touch layer, a pressure layer, a second control electrode layer and a protective layer, the multifunctional PTC graphene heating skin integrates touch, pressure, display and heating, a touch function and a pressure function are combined, that is, only when a touch signal exists and a pressure signal reaches a threshold value, the touch is identified to be valid, and a corresponding function is correspondingly executed, so that no touch is effectively realized; in addition, a PTC (Positive Temperature Coefficient) electric heating function is integrated, so that the vehicle interior trim can provide comfortable hand feeling temperature for a user in winter, and the vehicle interior trim is very practical. And the atmosphere in the vehicle can be improved through the light-transmitting display function.
本发明提供一种多功能PTC石墨烯加热表皮及其制备方法，属于汽车内饰中可透光的包覆饰面技术领域；包括表面层、图案层、电极层、石墨烯加热层、电容触控层、压力层、第二控制电极层和保护层；该多功能PTC石墨烯加热表皮，集触摸、压力、显示及加热于一体，其中触摸功能与压力功能结合，即只有当触摸有信号且压力信号达到阈值时，才会识别本次触摸有效，并对应执行相应的功能，有效方式了无触碰；除此之外，还集成了PTC电加热功能，使得在冬季车辆内饰也能为使用者提供舒适的手感温度，极为实用。透光显示功能还能提升车内的氛围。
