Publish Time: 2024-10-31
As an important functional inorganic filler, Nano Calcium Carbonate has been widely used in the field of composite materials due to its unique physical and chemical properties. However, Nano Calcium Carbonate particles are very easy to agglomerate and have poor compatibility with matrix materials, which limits its performance in composite materials. Therefore, surface modification of Nano Calcium Carbonate and improvement of its interfacial effect with matrix materials have become the key to improving the performance of composite materials.Surface modification mainly changes the properties of Nano Calcium Carbonate surface by chemical or physical methods, such as introducing functional groups, coating polymers, etc., to enhance its compatibility and bonding with matrix materials. The modified Nano Calcium Carbonate particles can be better dispersed in composite materials, reduce agglomeration, and thus improve the mechanical properties and processing properties of composite materials.In composite materials, the interfacial effect between Nano Calcium Carbonate and matrix materials is crucial. Good interfacial bonding can ensure the effective transfer of stress in the material and avoid stress concentration and crack propagation at the interface. The surface functional groups or polymer layers of the surface modified Nano Calcium Carbonate can form chemical bonds or physical entanglements with the matrix material, thereby enhancing the interfacial bonding force and improving the overall performance of the composite material.In summary, the surface modification of Nano Calcium Carbonate and its interfacial effect in composite materials are of great significance for improving the performance of composite materials. Through reasonable surface modification methods, the compatibility and bonding force between Nano Calcium Carbonate and the matrix material can be significantly improved, thereby preparing a composite material with excellent performance. In the future, with the continuous development and improvement of surface modification technology, the application prospects of Nano Calcium Carbonate in the field of composite materials will be broader.
