Method for preparing anisotropic conductive polymer composite

The invention discloses a method for preparing an anisotropic conductive polymer composite. The method comprises the following steps of: mixing 1.5 to 4.5 parts of carbon nano tubes and dispersing agents; ultrasonically oscillating the mixture for 0.5 to 1.5 hours; adding 100 parts of polyethylene i...

Summary:The invention discloses a method for preparing an anisotropic conductive polymer composite. The method comprises the following steps of: mixing 1.5 to 4.5 parts of carbon nano tubes and dispersing agents; ultrasonically oscillating the mixture for 0.5 to 1.5 hours; adding 100 parts of polyethylene into the oscillated mixture; continuously ultrasonically oscillating the mixture and mechanically stirring the mixture for 1 to 2 hours; filtering and drying the mixture; premixing the mixture and 10 to 60 parts of dry polycarbonate; placing the newly obtained mixture in a screw extruder for fusing,blending and extrusion; and thermally stretching the obtained product in normal temperature air, forcibly cooling the obtained product in a cooling water bath and cutting the obtained product with a granulator sequentially. The mixing orders of the conventional materials are changed by the method, so that dispersed phase polycarbonate forms microscopic filaments having good orientation and uniform distribution and the car
