Paper Abstract

In this paper we report for the first time in-situ measurements of corona poling induced SHG . We investigated a specially synthesized new amorphous polymer (PPNA) that contains p-nitroaniline as sidegroups covalently fixed to a polyethylene-type backbone. In addition, we did measurements on an amorphous alternating copolymer poly(vinylidenecyanide/vinyl-acetate) (PVDCN/VAc), known for its piezoelectric properties. In order to understand the nonlinear properties and their stability, an extensive characterization of the materials is necessary. Therefore, calorimetry, thermogravimetry, X-ray, dielectric relaxation, waveguide and absorption spectroscopy studies were performed. Fig. 1 shows the chemical structure of the polymers investigated.
