Poly Vinyl Cinnamate Index Optimize Waveguides - China

price: contact company for price

CAS: 9050-06-0 Under UV irradiation, poly(vinyl cinnamate) (PVCi) films

undergo cross-linking due to [2 + 2] photocycloaddition between

cinnamoyl groups. Consequently, electronic configuration of lateral

polymer groups changes and also leads to the drop of the refractive

index in the visible range. This mechanism is studied with regards to

the level of the electronic absorption of cinnamate centered at 278 nm.

It acts on refractive index by shifting the absorption UV band. Most of

the time, this influence vanishes in the near infrared region (NIR). It

is due to antagonist phenomena acting at the expense of the index

lowering. The causes analysis leads us to optimize the irradiation

spectrum, providing higher index contrasts between irradiated and

nonirradiated area. We show that strong index changes can be achieved in

PVCi film, up to 2.5 10-2 even in the NIR, enabling us, for example, to

perform optical photoprinting waveguides for telecommunication

wavelengths (1300-1550 nm).
