Abstract
The present application disclose a method for preparing an oriented heat conducting sheet, which includes the following steps: Step S, preparing a fluid composition for the heat conducting sheet; Step S, placing the fluid composition obtained in the step Sin an orientation molding device, applying a circumferential high-speed shear force to the fluid composition layer by layer to enable thermal conducting fillers in the fluid composition to be oriented along a shear direction to form an oriented thin-layer composition, and collecting the thin-layer composition layer by layer in a die to form a continuous multi-layer aggregate; Step S, heat curing the multi-layer aggregate to obtain an oriented composition block; and S, slicing the oriented composition block along the direction perpendicular to an orienting direction of the oriented composition block to obtain an oriented heat conducting sheet.
