Silica aerogel is a kind of gel material with dispersed medium as gas. It is a nanoporous fixed material with network structure composed of colloidal particles or polymer molecules, and its solid phase and pore structure are nanometer scale.

Graphene is a two-dimensional hexagonal lattice structure consisting of carbon atoms with a single atomic layer or atomic layer thickness.

3D printing technology has basically formed a system in technology, and the same applicable industries are gradually expanding.

The requirements of metal 3D printing for powder are mainly in chemical composition, particle shape, particle size, particle size distribution, fluidity, recycling and so on.

A wide variety of functional nanoscale materials and functional nanoscale surfaces are in use in consumer products, including cosmetics and sunscreens, fibers and textiles, dyes, fillers, paints, emulsions and colloids.

Nanomaterials and nanoparticles are used in a broad spectrum of applications. Today they are contained in many products and used in various technologies.

Nano-particle materials: When used directly, the morphology of nano-particles is called nano-particle materials. Ultra-fine particle catalysts, known as the fourth generation catalysts, can significantly improve the catalytic efficiency by using very high

Nanotechnology is the general term for designing and making anything whose use depends on specific structure at the nanoscale-generally taken as being 100 nanometres (100 millionths of a millimetre or 100 billionths of a metre) or less.

Sustainable development of energy and environment is two important development strategies of human society in the world today.

The pore size can be adjusted according to the actual application, and the chemical properties are stable and thermally conductive. High rate, good insulation performance and hydrophobic properties.
