Making a photo active fabric

[Daza]

Hi science guru's I'm doing some reaserch on photoactive fabrics that can change there composition when exposed to UV light. I'm in no way smart enough to know what I'm looking for so I was wondering if anyone could direct me. To give an Idea of what I'm looking for allow me to be more specific. I'm looking at fabric which can change from something that can let light throigh to something that can block light out with the transition being the disappearance of UV light turning the fabric solid.If anyone has done reaserch like this or knows where I can start my own reaserch into this there advice and help would be much appreciated.
