摘要

A halochromic hybrid textile for pH-sensing applications was designed by employing a non-toxic dyestuff, 7-Hydroxy-3H-phenoxazin-3-one (Resorufin), and an epoxy silane precursor, 3-glycidoxypropyltrimethoxysilane (GPTMS) through sol-gel method. The reaction mechanism and the formation of a polyethylene oxide network of GPTMS containing Resorufin were established by NMR characterization. The pH response of the hybrid halochromic system was studied by UV/Vis spectroscopy and compared with the pure Resorufin in different buffered solutions. Morphology and washing fastness of treated textile fabrics were evaluated by SEM, AFM and FT-IR analyses.
