AI Technical Summary

Problems solved by technology

For example, electronic components usually generate electromagnetic waves when they are working. This electromagnetic wave will become noise that interferes with the antenna in the electronic device, resulting in a decrease in the ability of the antenna to receive and send signals.

Embodiment 1

[0041] First, 7.5g of paraffin was weighed and heated at 70°C until completely melted. Next, add 1.6875g of silicon carbide (SiC) and 0.1875g of graphite sheet to the paraffin, and stir with a homogenizer for 2 hours (4000rpm) until the silicon carbide and graphite sheets are evenly dispersed in the liquid paraffin solution middle. Then, pour the solution into a square mold of 3cm×3cm, and pressurize it with a pressure of 17000lbf after solidification.

Embodiment 2

[0043] First, 7.5g of paraffin was weighed and heated at 70°C until completely melted. Next, 1.3125g of silicon carbide and 0.5625g of graphite sheets were added to the paraffin, and stirred for 2 hours with a homogenizer (4000rpm) until the silicon carbide and graphite sheets were evenly dispersed in the liquid paraffin solution. Then, pour the solution into a square mold of 3cm×3cm, and pressurize it with a pressure of 17000lbf after solidification.

Embodiment 3

[0045] First, 7.5g of paraffin was weighed and heated at 70°C until completely melted. Next, add 0.9375g of silicon carbide and 0.9375g of graphite sheet into the paraffin, and stir for 2 hours with a homogenizer (4000rpm) until the silicon carbide and graphite sheet are evenly dispersed in the liquid paraffin solution. Then, pour the solution into a square mold of 3cm×3cm, and pressurize it with a pressure of 17000lbf after solidification.

Abstract

The invention provides a composite material for electromagnetic wave shielding or electromagnetic wave absorption and a manufacturing method thereof. The composite material comprises an electromagnetic wave absorbing material and a conductive material. The electromagnetic wave absorbing material includes silicon carbide. The conductive material includes a two-dimensional carbon material including at least one of a graphite sheet and a graphene sheet.

Description

technical field [0001] The present invention relates to a composite material and a manufacturing method thereof, and more particularly relates to a composite material for electromagnetic wave shielding or electromagnetic wave absorption and a manufacturing method thereof. Background technique [0002] As the operation speed of electronic devices such as smart phones, tablet computers, and notebook computers continues to increase, the noise generated by electronic components in the electronic devices also continues to increase. For example, electronic components usually generate electromagnetic waves when they are in operation, and the electromagnetic waves will become noise that interferes with the antenna in the electronic device, resulting in a decrease in the ability of the antenna to receive and send signals. Therefore, in many electronic devices, electromagnetic wave shielding or electromagnetic wave absorbing structures are provided on the electronic components to prev...
