A comparative study of track registration response of Makrofol-(KG, KL & N) polycarbonate to Ar-40 ions

摘要

In the present work a comparative study of track registration response of Ar-40 ions in different types of Makrofol polycarbonates viz. Makrofol-KG, KI, & N have been done. The etched track parameters viz, bulk etch rate, track etch rate, etch rate ratio, cone angle and etching efficiency were calculated. The variation of etching rates with temperature were found to be exponential and follow the Arrhenius equation. The values of activation energy for bulk and track etching were also calculated. Maximum etchable track length/range were also obtained and compared with the theoretical values obtained from computer program RANGE. From the results it is found that the polycarbonates having same chemical composition manufactured by different chemical processes have slightly different behavior. [References: 13]
