Rheo-Optical Properties of Ion Irradiated Polystyrene Films

MRS Online Proceedings Library Aims and scope

Abstract

Rheological and optical properties of polystyrene are modified by 200 keV He irradiation because of new molecular bonds induced by ion energy deposition. Total amount of bonds, as calculated by optical measurements, increases linearly with ion fluence without any dependence on the initial molecular weight. Density of interchain bonds or crosslinks, as calculated by rheological measurements, increases linearly at low fluence ( ∼1013 ions/cm2), while for high values shows a saturation behaviour.

Correlation between optical and rheological measurements allows us to calculate the fractions of interchain and intrachain bonds of ion irradiated 9000, 35000 and 100000 initial molecular weight samples.
