Surface modification of carbon fibres using plasma technique

Käppler I., Hund R D, Cherif C.

Autex Research Journal

2014

Vol. 14, no. 1

34--38

For the development of a new generation non-crimp fabrics (NCF) made of carbon fibres, a feasibility study of different characterisation methods and surface treatments of the used carbon fibres needs to be performed. In order to join the carbon fibre layers with the binder for realising this new type of NCF, the surface topography and functionality of the fibres have to be analysed first. The wettability of the binder to the carbon fibre surface is of prime significance and needs to be enhanced. Here, the enhancement is carried out by improving the surface energy using atmospheric plasma of compressed air, argon and nitrogen. It is also proposed to improve the surface energy through chemical techniques.

Evaluation of the Photocatalytic Properties of Textile Fabrics Modifed with Titanium Dioxide of Anatase Structute

Te efect of surface modifcation with selected alkoxysilanes on the photocatalytic properties of TiO2 used in the reaction of formaldehyde photodegradation to UV radiation was investigated. Titanium dioxide - TytanpolŽ A-11, a pigment of anatase structure of the untreated surface, was used. Silane coupling agents were hydrolysed and then deposited directly on the surface of the TiO2. Te alkoxysilanes - 3-ethacryloxypropyltrimethoxysilane, vinyltrimethoxysilane or N-2-(aminoethyl)-3-aminopropyltrimethoxysilane were applied in the amounts of 0.5, 1 or 3 wt. parts per 100 wt. parts of TiO2. Te unmodifed and modifed titanium dioxide were used for the dip-coating of textile fabrics, and their photocatalytic properties were tested using UV radiation with TiO2 as a photocatalyst. Te results proved the very good photooxidative activity of TiO2 introduced into the structure of polyester fabric.
