Abstract
Dispersion of sol-derived nano-alumina in an organic solvent mixture containing a 1,2-diol with simple agitation. A thixotropic solution is obtained at 20% alumina in ethylene glycol, while a low viscosity (<100 cps) solution is possible for a 20% alumina in (1:1, N-methylpyrrolidone-ethylene glycol) solution. Alumina particles are de-agglomerated with minimal agitation. The resulting solution or resin solution is stable to settling and re-agglomeration. The nano-alumina dispersion solution can then be mixed with an imide coating to provide for a wire coating to give the wire improved abrasion, COF, and corona resistance.
