Contribution to the research on cellulose diacetate as a solid state track detector

Abstract
While having a similar composition to Cellulose Triacetate, Cellulose Diacetate is a less sensible heavy ions detector. With a 0.9 N potash etching at 20°C, ions which have higher Z than Carbon are not recorded and the Etch Rate Ratio is about 1 to 2 for Cu and Kr ions. The study of the infrared absorption spectra shows a decrease of the v(O-H) band intensity at 3500 cm−1 for CDA, when it increases for CTA.
