The properties of organic pigment encapsulated with nano-silica via layer-by-layer assembly technique

In this paper, an organic pigment was coated with nano-silica particles via layer-by-layer self-assembly technique and some properties were investigated. The results revealed that the coating of nano-silica on the surfaces of pigments could improve the thermal stability, wettability, acid and alkali resistance, and weatherability of the organic pigment.
