CONDUCTIVE POLYMERIC MATERIALS, PREPARATION AND USE THEREOF
Polymeric materials, particularly in the form of films, sheets or coatings, having electrical conductivity e.g. suitable for static dispersion. Conductivity is conferred by dispersed carbon nanoparticles such as CNTs. Particular embodiments are materials or articles for use on spacecraft, made from temperature-resistant polymers such as aromatic polyimides. Embodiments include optical solar reflectors having a reflective backing. Conductivity may be supplemented by an additional network conductor material which may be printed onto or embedded in the film.
Methods of processing particulate carbon material, such as graphic particles or agglomerates of carbon nanoparticles such as CNTs are provided. The starting material is agitated in a treatment vessel in the presence of low-pressure (glow) plasma generated between electrodes. The material is agitated in the presence of conductive contact bodies such as metal balls, on the surface of which plasma glow is present and amongst which the material to be treated moves. The methods effectively deagglomerate nanoparticles, and exfoliate graphitic material to produce very thin graphitic sheets showing graphene-type characteristics. The resulting nanomaterials used by dispersal in composite materials, e.g. conductive polymeric composites for electric or electronic articles and devices. The particle surfaces can be functionalized by choosing appropriate gas in which to form the plasma.

The application discloses methods of processing particulate carbon material, such as graphitic particles or agglomerates of carbon nanoparticles such as CNTs. The starting material is agitated in a treatment vessel in the presence of low-pressure (glow) plasma generated between electrodes, e.g. between a central electrode and an outer rotating conductive drum containing the material for treatment. Preferably the material is agitated in the presence of conductive contact bodies such as metal balls, or other contact formations with relatively high specific surface area, on the surface of which plasma glow is present and amongst which the material to be treated moves. The methods are found to effectively deagglomerate nanoparticles, and to exfoliate graphitic material to produce very thin (few- layer or monolayer) graphitic sheets showing graphene-type characteristics. The resulting deaggregated or exfoliated carbon nanomaterials are an aspect of the disclosure, as is their use dispersed in composite materials, e.g. conductive polymeric composites for electric or electronic articles and devices. The particle surfaces can be functionalised by choosing appropriate gas in which to form the plasma. The invention is advantageous in using safe, dry and moderate conditions to achieve a high degree of deaggregation or exfoliation compared with previous aggressive chemical methods such as acid treatment.
The application describes methods and apparatus for recovering materials from waste carpet and of the like products. The carpet material is initially shredded into coarse pieces. These are optionally dried and then subjected to cooling to embrittle at least one components, such as a polymer backing material, while leaving other component e.g. tuff fibres, flexible. In the cooled condition, the pieces are subjected to mechanical action such as hammering or rolling to break up the embrittled material, and these fragments are separated from the other material and recovered. Preferably a drying stage is applied after the mechanical fragmentation, before separation. The procedure may be repeated, optionally with different temperatures to selectively embrittle and fragment different components and facilitate their separation.
The application discloses methods for recycling polymeric materials, particularly cured rubber e.g. derived from tyres and the like. The polymer material is reduced to particulate form, and subjected to a surface activation treatment, preferably a cold gas plasma treatment. The resulting particles show excellent properties when blended with matrix or binder materials which are then cured or set to form new articles. In particular, the activated surfaces make intimate bonding contact with the surrounding matrix or binder, so that large proportions of particulate material can be recycled into new products which exhibit good performance, e.g. elastomeric performance.
