Chloroform with pmma
WebA method to produce thin layer of PMMA (poly (methyl methacrylate) films by spin coating is reported. PMMA is dissolved in xylene, a mixture of MIBK-xylene and chloroform. Varying the PMMA concentration and spin-coating speeds controls the thickness of the PMMA films. Using chloroform as solvent evidenced thickness around 10 μm. Webchloroform and purple for PMMA. Fig. S1A shows the full spectrum of the standard solution. The standard sample was made by dissolving 53.7 mg of PMMA and 13.2 mg of chloroform in deuterated acetone. Peaks (a), (b), and (c) were identified with the methyl ester, methylene, and methyl groups of PMMA, respectively.
