John M. Torkelson focuses on Glass transition, Polymer, Polystyrene, Polymer chemistry and Composite material. His work deals with themes such as Relaxation, Thin film, Fluorescence, Layer and Relaxation, which intersect with Glass transition. John M. Torkelson is involved in the study of Polymer that focuses on Methyl methacrylate in particular.
His Polystyrene study incorporates themes from Analytical chemistry, Pyrene, Methacrylate, Fluorescence spectrometry and Diluent. His biological study spans a wide range of topics, including Copolymer, Gradient copolymers, Differential scanning calorimetry, Physical aging and Polymer substrate. His work on Nanocomposite, Spin coating and Rheology as part of general Composite material research is often related to Solid-state, thus linking different fields of science.
His main research concerns Polymer, Composite material, Polymer chemistry, Glass transition and Polystyrene. His Polymer research is multidisciplinary, relying on both Chemical physics, Thin film, Fluorescence, Analytical chemistry and Diffusion. His work in the fields of Composite material, such as Shear, Nanocomposite, Polypropylene and Polymer blend, intersects with other areas such as Solid-state.
His Polymer chemistry study also includes fields such as
John M. Torkelson mostly deals with Polymer, Composite material, Polymer chemistry, Polystyrene and Glass transition.
