Eco-environmental materials

Developing eco-friendly materials is one of the important research contents of polymer materials in the future, but comprehensive research should be carried out according to their uses and whether they have a far-reaching impact on the environment. By prolonging the service life of polymer materials, the utilization rate of resources is improved and the speed of resource development is reduced. At present, Japan is in a leading position in the research of long-life polymer materials. The long-life blue and green organic luminescent materials were developed by Japan Chuxingguang Science Co., Ltd., and the molecular structure of the blue organic luminescent materials was improved, so that the current luminous efficiency of 9 CD/a and the half-life of 223000h were obtained, which not only improved the color purity of the green organic luminescent materials, but also prolonged their life. Wei Lan et al. studied fumed silica and composite insulating materials for long-life thermal batteries. When the temperature of thermal simulation material is 500℃ and the density is 0.265 g/em, the thermal conductivity is 0.0629 w/( 1 1k), which is close to the level of similar materials in the United States.
