Abstract:
The optical modulating glass that smartly regulates indoor solar radiation by
changing their optical transmittance in response to thermostimuli is developed as a
promising solution toward reducing the energy consumption of the building. The recent
work investigated the synthesis of thermoresponsive hydrogel prepared with
thermochromic vanadium dioxide (VO2) particles which are dispersed in poly Nvinylcaprolactam
(PNVCL) hydrogel matrix. Hydrogel composite was prepared between
two pieces of glass to form the sandwich structure. Firstly, VO2 particles were successfully
prepared via hydrothermal process, the percent yield of VO2 was equal to 85.84 and XRD
analysis showed that VO2 monoclinic structure was obtained with 100% of purity. Secondly,
hydrogel composite was prepared by photopolymerization with a different concentration of
monomer and weight of photoinitiator. The percent conversion vs concentration plot is
almost linear up to about 80% conversion with concentration more than 230 mg/ml and
the result showed that weight of photoinitiator does not affect percent conversion of
monomer. The suitable time for polymerization was 6 hours. FTIR and 1H-NMR results
showed that polymerization takes place by the opening of carbon-carbon double bond
without any change in the caprolactam ring. Finally, the hydrogel composite was transparent
while the temperature is lower than LCST (25 °C) and opaque while the temperature is
higher than LCST (40 °C).
