摘要（英）：

The invention discloses a high-insulation one-way heat conducting polyimide film and a preparation method thereof. The high-insulation one-way heat conducting polyimide film is of a double-layer structure and comprises a polyimide heat insulation layer and a polyimide heat conducting layer; the polyimide heat insulation layer is obtained by curing a polyimide heat insulation coating; the polyimide heat insulation coating contains the materials according to the weight percentage: 6-20 % polyimide resin, 30-85 % solvent and 10-60 % heat-insulating filler; the polyimide heat conducting layer is obtained by curing a polyimide heat conducting coating; the polyimide heat conducting coating contains the materials according to the weight percentage: 6-20 % polyimide resin, 30-85 % solvent and 10-60 % heat conducting filler; and the high-insulation one-way heat conducting polyimide film has a high-insulation one-way heat conducting characteristic and can be used as a flexible heating film base material to improve an energy-saving effect. The preparation method comprises the steps: a, preparing the heat insulation coating; b, coating the heat insulation coating on the surface of a glass substrate; c, curing the heat insulation coating at a low temperature; d, preparing the heat conducting coating; e, coating the heat conducting coating on the heat insulation layer; and f, curing the heat conducting coating at a low temperature to obtain the heat conducting layer.
