Types and Origin




Generic types of thermochromic polymers classified by the effect on light causing the thermochromic behavior

effects on light origin macroscopic behavior polymer class
reflection periodic structures ΔI, Δλmax cholesteric liquid crystalline polymers
crystalline colloidal arrays embedded in a gel-network
gels
absorption chromophoric groups ΔI, Δλmax conjugated polymers
hydrogels containing indicator dyes
scattering areas with different refractive indices ΔT% polymer blends exhibiting LCST
hydrogels exhibiting LCST
lyotropic liquid crystalline hydrogels
       
LCST: lower critical solution temperature
