Preparation and Electromagnetic Wave-sensitivity of Poly(N-isopropylacrylamide) Gels Containing Polymer-grafted Carbon Microcoils

抄録

Thermo-sensitive polymer, poly(N-isopropylacrylamide) (PNIPAM), was grafted onto carbon microcoils (CMCs), and composite gels of polymer grafted CMCs and PNIPAM were prepared by photo-polymerization. The composite gels were shrunken with increase of temperature as well as normal PNIPAM gel and responded to electromagnetic waves with the presence of contained CMCs which absorb electromagnetic waves and generate heat. The surface temperature of composite gel was reached 43C^owithin 150s and changed its shape with squeezed water.
