Abstract
A method fabricates a transparent polymer plate or film. The method incudes applying an acrylate ink to a transparent substrate and illuminating the polymeric substrate and the acrylate ink with a light source to cause photopolymerization. The photopolymerization creates micro-louvre structures inside the transparent polymeric plate or film.
Claims20
A method to make a transparent polymer film, the method comprising:
- coating a transparent polymeric substrate with an acrylate ink;
- adjusting a distance between a light source and the transparent polymeric substrate;
- and
- illuminating the transparent polymeric substrate and the acrylate ink with the light source to cause photopolymerization that creates the transparent polymer film with micro-louvre components inside the transparent polymer film.

A method to make a transparent polymer plate, the method comprising:
- applying an acrylate ink to a glass substrate;
- and
- illuminating the glass substrate and the acrylate ink with a light source to cause photopolymerization that creates the transparent polymer plate with micro-louvre structures inside the transparent polymeric plate.
A transparent polymer film fabricated from a method comprising:
- applying an acrylate ink to a Poly(methyl methacrylate) (PMMA) substrate;
- adjusting a distance between a light source and the PMMA substrate;
- adjusting an angle between the light source and the PMMA substrate;
- and
- illuminating the PMMA substrate and the acrylate ink with the light source to cause photopolymerization that forms micro-louvre components inside the PMMA substrate.
