Effect of Some Selective Surfactants on the Thermochromic Behavior of Polyvinyl Alcohol-Borax Gel

Naorem Shubhaschandra Singh


The phenomenon of changing colour intensity of PVA-Borax hydrogel in presence of surfactants like sodiumdodecyl sulfate (SDS), trimethyl triammonium bromide (TTAB) has been investigated in detail. The preparation of thermochromic Borax crosslinked PVA gel was performed by embedded with a pH sensitive dye (phenolphthalein) both in absence and presence of surfactant. The phenomenon of thermochromism in presence of surfactant was studied spectrophotometrically.
