Low structure materials refer to those materials with little or no definite structure. These substances are usually composed of a large number of molecules or atoms, and the arrangement between them is not fixed or regular. Low-structure material is a kind of material with wide application and development trend in modern science and technology. These materials have high surface area, can adsorb and release molecules, and have some unique physical and chemical properties, such as high flexibility, low density and high strength. There are many kinds of low-structure materials, the most common ones are foam, gel and powder. Foam is composed of gas and liquid, with many pores and large surface area. Gel usually consists of a network structure of high molecular polymers or inorganic substances, and has a large surface area. Powder is composed of many fine particles and can withstand a large number of chemical reactions. These materials have loose and open structures and large surface areas, and are widely used in chemical reactions and physical adsorption.

Low-structure materials are characterized by very fragile structures and easy compression, so they must be effectively treated with very little force. These materials are widely used in mechanical engineering, aerospace, chemistry, biomedicine and environmental protection technology.

The diffusion and adsorption of low-structure materials make them effective catalysts. They can change the rate and selectivity of chemical reaction process by adsorbing reactants and carrying out chemical reaction on the surface. These materials can be used to control the size and shape of suspended particles and aerosols, and to adsorb and separate gases, liquids and solids. For example, powder materials are widely used for gas treatment, storage and separation.

Low-structure materials are the basis of building new nano-materials. Can control and assemble low-structure materials to make them have certain orientation and structure. These tissue materials are widely used in biomedicine, nanomaterials, energy storage and conversion, optoelectronics, sensors and information technology. For example, by assembling carbon nanotubes and metal oxide nanoparticles into a low-dimensional structure, efficient photovoltaic cells, energy-saving chemical catalysts and efficient sensors can be manufactured.

In a word, low-structure materials have a very broad application prospect. Their applications in materials science, nano-science and chemical engineering are constantly developing and improving, and will play an increasingly important role in daily life and industrial fields.
