Application of stearic acid in surface modification of nanometer calcium carbonate

there are two major shortcomings in the application of nano-calcium carbonate in organic media: first, nano-calcium carbonate is an inorganic material with a hydrophilic and oleophobic surface. it has poor dispersion in polymers and poor affinity with organisms, and it is easy to form agglomerates. the direct application effect is not good, resulting in a…
