Scientific Study from the year 2009 in the subject Physics - Nuclear Physics, Molecular Physics, Solid State Physics, grade: A, language: English, abstract: Investigations were carried out on etching behaviour of an engineering polymer Kapton-H (4-4'-oxydiphenylene pyromellitimide). Kapton-H samples were subjected to etching in 4N NaOH at 400 C and at 500 C temperatures in pristine as well as irradiated form. Irradiation of pristine Kapton-H specimen was done using 75 MeV/nucleon O+ ion beam of fluence 1.875 x a trillion ions/cm2. The specimen was exposed to etchant for a period of 150...
