A polymeric material which includes optionally substituted vinyl alcohol moieties is used as an energy absorbing means. The polymeric material may be a copolymer. Electrolytes may be associated with the polymeric material to adjust its energy absorbing properties. The polymeric material may be associated with a carrier which may allow gel formation. The material described may absorb thermal energy or electro-magnetic energy. The heat adsorption properties of a poly(vinyl alcohol - vinyl acetate) copolymer and the product of its reaction with poly (1,4-di (4-(N-methylpyridinyl))-2,3-di (4-(1-formylphenyl) butylidene are described. A vehicle may be masked from detection by radar by spraying it with fluid containing the material. |
