Abstract
The present invention relates to ceramer compositions capable of being cured to form antistatic, abrasion resistant ceramers. The ceramer compositons comprise a plurality of colloidal silica particles, a binder precursor, and an electrically conductive organic polymer, for example, polythiophene. The present invention also relates to ceramer articles, for example, ceramer coatings and shaped ceramer particles made from the ceramer compositions and to methods of making the ceramer compositions and ceramer articles.
