Dichroic film measurement using spectroscopy

A better stretch ratio, and thus also a higher degree of orientation, can be obtained by casting a solution of P30T on a polyetylene (PE) foil, and stretching the structure as a whole. This method is also preferred, since films with a thickness suitable for UVA IS/NIR spectroscopy can be used. Fig. 3 shows the band at 1510 cm-i of a P30T/PE structure, which was stretched to a final stretch ratio 1 / 1q = 3. The measured dichroic ratio is D = 14, which gives... [Pg.371]
