High-graphitization graphite thick film and preparation method thereof
The invention discloses a high-graphitization graphite thick film and a preparation method thereof, and belongs to the technical field of graphite thick films. The method firstly prepares a nanosheet material doped polyimide film, and then sequentially carrying out carbonization treatment and graphitization treatment on the film to obtain a high-graphitization graphite thick film. The process is simple, spraying is not needed in the preparation process, practicability is high, energy is saved, industrial production is easy to achieve, and wide industrial prospects are achieved. The graphite thick film prepared by adopting the method is light in weight and has flexibility, the introduction of a nanosheet material is beneficial to improving the graphitization degree in the polyimide thick film, and the problems that a finished product is fragile, the internal graphitization is incomplete and the like are solved, so that the electric conduction and heat conduction properties of the finished product are improved, and the application range of the finished product is widened.
本发明公开了一种高石墨化石墨厚膜及其制备方法，属于石墨厚膜技术领域。本发明先制备纳米片层材料掺杂聚酰亚胺薄膜，再将其依次进行碳化处理和石墨化处理，得到高石墨化石墨厚膜。本发明工艺简单，制备过程中不需要喷涂，实用性强，节约能源，易于实现工业化生产，具有广阔的工业化前景。采用本发明方法制备的石墨厚膜重量轻、且具有柔性，纳米片层材料的引入有助于提高聚酰亚胺厚膜内部的石墨化程度，解决了成品易脆以及内部石墨化不完全等问题，从而提高了成品的导电和导热性能，拓宽了其应用范围。
