An effective etching technique for polycarbonate/core‐shell poly(butyl acrylate)‐poly(methyl methacrylate) blend

Abstract

Abstract Two etching techniques are used to reveal the morphology of PC/PBA‐ cs ‐PMMA blend. One is based on acetic acid (CH 3 COOH) solutions, whereas the other uses CCl 4 /C 2 H 5 OH (3/1 v/v). The latter approach shows to be more appropriate and successful for revealing the morphology of PC/PBA‐ cs ‐PMMA blend.
