Paper Abstract

Poly (vinyl alcohol) [PVA] is a photo-induced cross-linking polymer, water-soluble, biocompatible, used in holography, nonlinear optics, as tissue engineering scaffolds and as polymer matrices for enzymes immobilization. PVA has been investigated for use as binder polymer in optical waveguides for sensor applications. The Y-shaped waveguides is composed of a buffer layer (lower refractive index) - SiO2, a core layer (higher refractive index) - PVA doped for the refractive index and sensibility increasing and a cladding layer (lower refractive index) - an other polymer. The light propagation in doped PVA waveguides represents the sensing element of the sensor. The preliminary results suggest that doped PVA polymers are promising for optical (bio)chemical sensors; the processes used to make them, represent environmentally friendly technology.
