Nanocellulose is a microfiber material extracted from plant fibers, with unique physical and chemical properties such as high strength, light weight, transparency and biocompatibility. These characteristics make their application in fine art pigments very potential. Application of nanocellulose in art pigments 1. Pigment dispersant: Nanocellulose can be used as an excellent dispersant to help the pigment particles disperse evenly in solution. Due to its surfactivity, it can effectively prevent the aggregation of pigment particles, thereby improving the color saturation and stability of the pigment. 2. Thickener and film forming agent: Nanocellulose can be used as a thickener in pigments to adjust the rheology of the pigments and increase the viscosity of the coating. This helps to have better control over brushstrokes and levels when painting. At the same time, nanocellulose can also form a transparent film, enhancing the adhesion and wear resistance of the pigment. 3. Environmentally friendly pigments: Nanocellulose, as a natural biological material, is renewable.
