NOVELTY - A wave-absorbing coating comprises 4-6 wt.% graphene, 5-30 wt.% organic solution of polyaniline/polyurethane polymer, and remaining additive. USE - Wave-absorbing coating e.g. infrared absorbing coating for preparing absorbing film (all claimed) in fabric, weapons, architectural glass, automobile glass and metal skin surface. ADVANTAGE - The absorbing coating high excellent adhesion, high temperature resistance and aging resistance, and provides absorbing film using simple process with low emissivity, which is invisible in near-infrared and infrared multi-spectral. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of absorbing film, which involves adding 3-10 mL absorbing coating in a flat-bottomed container, adjusting the distance between an inverted conical funnel-shaped steam-water distributor in the solvent dissipating device, and activating an air pump to aerate water and solvent in the flat-bottomed container. The water volume of the air pump is 4-5 L/hour. The liquid surface in the flat-bottomed container is 2.0-3.0 cm.
