文摘:This work proposes a novel protocol to evaluate a water profile inside polymers and composite materials at a microscopic scale. Scanning Electrochemical Microscopy (SECM) experiments are performed in a dry Room Temperature Ionic Liquid (RTIL) to detect water molecules coming from an organic matrix composite that was previously immersed water. Since the presence of water influences the viscosity of the RTIL, the electrochemical signal at the SECM tip is sensitive to the amount of water around the microelectrode. Several water profiles of dry, semi-saturated and saturated composite sample are obtained and compared.
