The present invention provides a post-fabrication modification approach for the fabrication of colored and chromic materials and sensors using plasma surface modification to covalently bind the coloring agent to the substrate, thus avoiding leaching of the dye. Advantageously, in said methods, said coloring agent is a dye or pigment linked to a radical sensitive functional group, such as an alkenyl or alkynyl functional group, and is applied to the substrate prior to the gas plasma treatment. The methods envisaged herein are generic in nature, which allow the covalent immobilization of various dyes on different materials. The covalently coated materials after plasma surface modification, particularly the covalently coated chromic materials and sensors, can be used in many different applications, such as protective textile and wound dressing applications.
本发明提供了一种后加工修改方法,用于制备彩色和变色材料以及传感器,利用等离子体表面改性将着色剂共价结合到基底上,从而避免染料的渗漏。在所述方法中,所述着色剂是与自由基敏感的官能基(例如烯烃或炔烃官能基)连接的染料或颜料,并且在气体等离子体处理之前应用于基底。本文所设想的方法是通用的,可以在不同材料上共价固定各种染料。经过等离子体表面改性后共价涂层的材料,特别是共价涂层的变色材料和传感器,可以用于许多不同的应用,例如防护纺织品和敷料应用。
