Structural coloring of P(St-MMA-AA)liquid photonic crystals on different fabric surfaces
Research on the application of liquid photonic crystals(LPCs)has primarily focused on polyester fila-ment fabric substrates.To investigate the effect of fabric with different materials on the self-assembly of poly(styrene-methyl methacrylate-acrylic acid)P(St-MMA-AA)LPCs,cotton,silk and polyester fabrics are used as substrates to prepare structural colors fabrics by rod-coating method,respectively.The results show that P(St-MMA-AA)microspheres can generate bright structural color on the fabric surface.However,the amount of LPCs consumed by cotton and silk fabrics with better hydrophilicity are higher than that of polyester fabrics with flat and smooth surfaces.Additionally,the reflectivity of cotton and polyester fabrics is slightly higher than that of silk fabrics.At the same time,the hue of the structural colors can be modulated by changing the particle size of P(St-MMA-AA)and the structural colors are red-shifted as the particle size increases.The P(St-MMA-AA)microspheres are regularly arranged in face-centered cubic structure on different fabric surfaces.
