Chemical Etching Behaviour of a Polyimide

Scientific Study from the year 2009 in the subject Physics - Nuclear 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...
