Diffuser is a common chemical material used to improve the dispersion of dyes and pigments, making them more soluble in solvents. And the dispersants NNO and CNF are two common dispersants, which have some differences in properties and applications

From a chemical structure perspective, NNO is a naphthalene based compound, which contains nitrogen atoms in its chemical structure. CNF is nanocellulose, a fibrous biomass material. The difference in chemical structure between these two leads to their different properties in certain aspects

From the perspective of usage scope, NNO is mainly used for the dispersion of dyes and pigments. It can evenly disperse dyes and pigments in solvents, improving the dyeing performance of dyes and the coloring effect of pigments. CNF, on the other hand, is more widely used in the fields of paper, coatings, and fillers. It can enhance the strength and conductivity of materials, improve the glossiness of paper, and enhance the coating performance of coatings

In addition, there are differences in the production processes of dispersants NNO and CNF. The preparation of NNO is usually achieved through chemical synthesis, which requires the use of a series of chemical reagents and reaction conditions. The preparation of CNF relies more on biomass resources, using technologies such as enzymatic hydrolysis and nanoprocessing. This gives CNF certain advantages in terms of environmental friendliness and sustainability

In terms of application, NNO and CNF also have some similarities. They can all serve as dispersants to improve the dispersibility of pigments and dyes. In addition, they all have good stability and solubility, can effectively dissolve in various solvents, and disperse dyes and pigments evenly

In summary, there are some differences between the dispersants NNO and CNF in terms of chemical structure, application scope, and preparation process. NNO is mainly used for the dispersion of dyes and pigments, while CNF is more commonly used in fields such as paper and coatings. In addition, their preparation processes are also different, and CNF has advantages in environmental friendliness and sustainability. But in some aspects, they also have some similarities. I believe that through the introduction in this article, readers can better understand the characteristics and applications of dispersants NNO and CNF.
