Broadband and crack-free low cost antireflection self-assembled nanocoating

E’ stato considerato l’uso di strati nano-strutturati realizzati in Polidimetilsilossano (PDMS) come rivestimento antiriflettente a basso costo da utilizzarsi su substrati di vetro. Il nanocoating realizzato riduce del 25% la componente riflessa dalla superficie di vetro.

Polydimethylsiloxane (PDMS) nano-structured layers were investigated as possible candidates for inexpensive coatings to be used on glass substrates. The main idea was to use a mature manufacturing process, developed for moulding a single layer of micro-hemispheres on a PDMS thin film, to create a single layer of nano-hemispheres that could act like a nano-structured coating. The nano-hemispheres were created by using a self-assembly process and the obtained nanocoating show an improvement in the transmission of the glass. In particular, the reflected component from a single glass surface passes from 4% (uncoated) to less than 3% when the anti-reflection coating is placed on it, this is equivalent to a 25% reduction of the reflected component from the glass surface.
