ABSTRACT
Polymer membranes are widely used in separation technology. Separation performances of such membranes depend on their track or pore size. Sometimes it is challenging to optimise the size in transparent membrane. Here, attempt has been paid to overcome this issue. In present work, we propose the development of nuclear tracks in transparent polymer membrane. Transparent membrane was doped with FeCl3 at very low concentration. Objective for such low doping is just colour the membrane from transparent to yellowish to visualisation of tracks. Irradiation of heavy nuclear particle was used to create loosely bounded structure. These doped irradiated membranes were allowed to etch chemically. Relatively longer etching makes these tracks visible under digital optical microscope. We have reported the variation in track size with etching time.
