PMMA/MMA is attacked by acetone, chlorobenzene, concentrated NH3, HF (after more than a few seconds, depending on strength).DC conductivity of the films was measured in the temperature range 303-393 K. Solid polymer electrolyte films of PMMA with NaClO 4 and NaClO 4 + plasticizer (dimethyl foramide) have been prepared by solution cast technique. PMMA/MMA is resistant to water, IPA, methanol, HCl, dilute NH3, dilute H2SO4, dilute HF for short periods, H3PO4 for short periods, dilute HNO3 importantly it’s also resistant to TMAH based developers. Effect of plasticizer (DMF) on electrical properties of PMMA.The best resolution attainable with PMMA/PMMA bilayer is around 10nm using a well focused beam and a very good process. Polarityįor large structures (above 1µm) the clearing dose at 100kV is around 600♜/cm 2, for small isolated structures it can go up to about 3000♜/cm 2.
