Abstract
Nitrogen doped polymeric carbon is prepared by reacting stannic chloride with a primary amine at an elevated temperature. The process is useful for coating glass to make reduced solar energy transmittance automotive and architectural glazings.
Claims12
A process for preparing nitrogen doped polymeric carbon, comprising contacting stannic chloride with a primary amine at a temperature sufficient to form nitrogen doped polymeric carbon comprising at least about 40 mole percent carbon.
A process for depositing a nitrogen doped polymeric carbon film onto a surface of a substrate, comprising contacting stannic cholride with a primary amine adjacent the surface of the substrate at a temperature sufficient to form a film of nitrogen doped polymeric carbon, comprising at least about 40 mole percent carbon, on said surface.
