主　　题：Lycium ruthenicum anthocyanins pH indicator environmental monitoring smart textiles 

摘      要：An eco-friendly and visual pH indicator was developed based on cotton fabrics dyed with natural Lycium ruthenicum extract(LRE),whose color changed from red to purple,blue and green at pH of *** methods for dyeing cotton fabrics with LRE were attempted,namely pre-mordanting,simultaneous mordanting,and post-mordanting methods with different dyeing temperatures,dyeing times and dyebath pH *** cotton fabrics exhibited the highest K/S value when they were dyed under a dyebath of pH 6 at 20℃for 90 min in the case of the simultaneous mordanting ***,the dyed cotton fabrics also showed reversible pH-dependent color *** developed flexible pH indicator based on renewable natural materials is suitable for multiple applications in environmental monitoring and smart textiles.
