The present invention relates to an emeraldine base composite, its preparation, and use as an effective anticorrosive pigment additive for corrosion inhibition. The emeraldine base composite comprises an insulating form of polyaniline or its derivatives adhered to an inorganic or organic material substrate such that the emeraldine base covers from about 1-100% surface of the material. Inter alia, the emeraldine base composite can be added to a coating as an anticorrosive pigment additive that inhibits corrosion and as a filler material that increases strength and barrier properties of coating.

A waterborne heat-insulation coating uses a silicon dioxide dispersion with silicon dioxide evenly dispersed in resin through a sol-gel method as a heat-insulation agent; since the silicon dioxide dispersion has great fineness and large specific surface area of between 30.1 and 100 m.sup.2/g, the waterborne heat-insulation coating when applied to building surfaces forms a coating layer that features a packed structure, a smooth surface, and a high surface reflectivity of 85% or more; resulted in that the coating layer can effectively block infrared rays and provide excellent thermal shielding effects, stain resistance, and durability.
