Plasma Deposition of an Anti-microbial Coating onto Polyester

The Challenge

A fabric treatment manufacturer approached Ceram to determine the efficiency of plasma deposition of an anti-microbial coating onto polyster.

What We Delivered

ToFSIMS (Time-of-Flight Secondary Ion Mass Spectrometry) was used to 'fingerprint' the surface of the untreated fabric and the treated fabric.

Selected significant signals associated directly with the coating and the fabric were then chemically mapped to illustrate the efficiency of the coating (see below). Key signals were then overlaid using colour maps to demonstrate the coating layer distribution.

Chemically Mapped Fabric Coating

Value to the Client

From the analytical work that Ceram's experts carried out, the client was able to modify their plasma deposition process to improve coating over the fabric surface.
