Chemical modification and dispersion is to use the surface groups of nanoparticles to form chemical bonds with reactive organic compounds. The nanoparticles are soluble in organic media due to the branched chains or groups of organic compounds on the surface. dispersion in. There are usually two ways of chemical modification: one is to use the end groups of macromolecules to chemically react with ...

Nanomaterials exhibit many exotic properties that traditional materials do not have. The first thing we need to know is that the nanometer (mainly refers to less than 100nm) of the composition of nanomaterials has four major effects: 1. Small size effect The boundary conditions of the crystal periodicity are destroyed; the atomic density near the surface layer of the amorphous nanoparticle decreas...

Manganese dioxide (chemical formula: MnO2) is a black or brown solid, the most stable oxide of manganese, and is often found in pyrolusite and manganese nodules. Pylusite is the main mineral containing manganese; manganese nodules (submarine rock solids) also contain manganese. Manganese dioxide is mainly used to make dry batteries, such as carbon-zinc batteries and alkaline batteries; it is also ...

In building energy conservation, the light transmission and heat insulation of glass is a very critical issue. In buildings with transparent ceilings and large-area exterior windows, the thermal radiation of sunlight will lead to an increase in the energy consumption of air conditioners, resulting in a large energy waste. In order to improve this phenomenon, nano-scale antimony doped tin oxide ATO...

In summer, the sun is strong, and the sunlight enters the room through the glass, causing the temperature in the car to rise sharply, which seriously affects the comfort of living and vehicle riding. Among them, the energy in the infrared band accounts for the largest proportion, and it is also the main source of energy for the temperature increase in the place where the sunlight is irradiated. By...
