摘要: Abstract The local glass transition temperature ( T g ) of heterogeneous polymer surfaces has been successfully determined by lateral force microscopy (LFM) on the submicron–nanometer scale. This paper addresses interfacial confinement effects in thin films blends and emulsions from polystyrene (PS), poly(butylmethacrylate) (PBMA) poly(methylmethacrylate) (PMMA). difficulty thermal rheological experiments with a microscopic scanning technique, introduces an in-situ calibration method.
