| titleOfInvention | Shape memory polymer composite material with electromagnetic shielding function and preparation method thereof |
| abstract | The invention discloses a shape memory polymer composite material with an electromagnetic shielding function and a preparation method thereof, wherein the preparation method comprises the following steps: (1) ultrasonically dispersing graphene oxide in water to form uniform dispersion liquid, adjusting the pH to 4-5, then dissolving a silane coupling agent in ethanol, adding the ethanol into the dispersion liquid, performing coupling reaction, cooling after the reaction is finished, and centrifugally washing; carrying out freeze drying to obtain chemically modified graphene oxide; (2) melting, extruding and blending 0.5-5 parts by mass of chemically modified graphene oxide, 5-20 parts by mass of carbon nano tubes, 0.5-3 parts by mass of antioxidant and 75-95 parts by mass of resin, then carrying out hot press molding, and finally carrying out electron beam irradiation on a sample to obtain the shape memory polymer composite material with the electromagnetic shielding function. The composite material has good electromagnetic shielding performance, excellent shape memory performance, aging resistance and the like. |
