BIODEGRADABLE COMPOSITES FOR SHIELDING OF ELECTROMAGNETIC WAVE CONTAINING CARBON NANOMATERIALS AND BIODEGRADABLE POLYMER AND A FABRICATION PROCESS THEREOF

摘要

PURPOSE: A composite for a biodegradable electromagnetic wave shield is provided to have the electromagnetic wave shielding function; reduce the environmental pollution; have an effect of weight reduction of car and the fuel efficiency increasing effect; and enable the nature friendly disposal. CONSTITUTION: A composite for a biodegradable electromagnetic wave shield includes 60-90 weight% of a biodegradable polymer; 10-40 weight% of a carbon nanomaterial. In addition, a manufacturing method of the biodegradable composite comprises a step of drying the carbon nanomaterial and the biodegradable polymer in the drying furnace; a step of manufacturing the composite by using an extruder after melting the dried carbon nanomaterial and the biodegradable polymer; a step of manufacturing a specimen of the composite for the biodegradable electromagnetic wave shield by inserting the composite into the compression molding machine.
