Preparation and characteristics of perdeuterated polystyrene films
Perdeuterated polymer film is a typical target of fast ignition physics. Perdeuterated polystyrene (DPS) was synthesized by free radical polymerization, and DPS films with thickness from 30nm to 450μm were prepared by dip coating and casting. The influence of the random disturbance occurred at gaslliquid interface on the thickness distribution of the DPS films would be reduced by clean substrate and cover on the substrate or mould. The thinner films can be obtamed with PVA as stripping agent. The glass transition temperature of the DPS film is relevant to its heat history. Annealing slowly increases the Tg and storage modulus of the films.
