Plasma deposition of polymer films on pmma powders using vacuum fluidisation techniques

Abstract

Thin organic films were deposited on polymethylmethacrylate powder particles by combining the techniques of plasma polymerisation and vacuum fluidisation. The treated powders were characterised by scanning electron microscopy, energy dispersive X-ray analysis, and time of flight secondary ion mass spectrometry. The primary objective of the investigation was to demonstrate the efficacy of the two techniques in combination for modifying the surface properties of particulate materials.
