The Hangzhou Asian Games are in full swing, and recently, the scene of the main torch being ignited by the integration of digital and physical elements at the opening ceremony of the Asian Games is impressive. It is worth mentioning that this Asian Games torch not only adopts a solemn and atmospheric shape with a fusion of square and circle, as well as a gradient color matching of Dangui gold and Hongyun purple, but also uses exquisite materials - the metal part of the torch body is formed by spinning 1070 aluminum alloy, and the surface has undergone two processes of laser engraving and anodizing quenching; The grip part is made of recyclable biomass material, which is environmentally friendly, lightweight, and easy to hold. From the Asian Games ritual vessels to venue construction, from consumables to sports equipment, various new materials were applied at the Hangzhou Asian Games around the concept of "green, intelligent, frugal, and civilized" competition organizing. The outer wall of the venue is covered with self-cleaning film, overlooking the Shaoxing Baseball (Baseball) Sports and Cultural Center located in Yuecheng District, Shaoxing City. A huge white canopy can be seen, like overlapping wings shading the venue. From a ground perspective, the unique design and color scheme make it look like floating above the venue. This canopy is called 'Cloud Wing' and covers an area of 21000 square meters. The bottom of the canopy is covered with curved white perforated aluminum plates, and light can shine through the canopy to the entrance hall. "A staff member of the operation team of the Shaoxing Baseball (Softball) Sports Culture Center introduced that the feathers of birds have waterproof and anti fouling grease, which can to some extent keep their feathers clean. Similarly, the "Cloud Wing" also has a protective coating, and the surface of the canopy is covered with PTFE film with titanium dioxide coating, which also gives the venue self purification capability. In addition to the "Cloud Wing", the exterior curtain walls of the Hangzhou Olympic Center Stadium and Hangzhou Olympic Center Tennis Center are covered with a layer of nanoscale titanium dioxide photocatalytic protective film to maintain the venue's usual freshness and reduce maintenance costs. Titanium dioxide can catalyze the decomposition of bacteria and pollutants using natural light, with high catalytic activity and good chemical stability. It is widely used in cosmetics, antibacterial and decontaminating agents, and chemical catalysts. The nanoscale titanium dioxide photocatalytic protective film applied to three Asian Games venues this time can quickly decompose the dirt on the building surface under the irradiation of sunlight. When it rains, the decomposed dirt will be washed away by the rainwater, thereby achieving self-cleaning of the building and maintaining the color of the exterior wall. Chen Naxin, Chairman of Zhejiang Harmony Photocatalytic Technology Co., Ltd., said that it is the first time in the world that photocatalytic materials have been applied on a large scale in international large-scale event venues. In the future, this material can also be applied in industries such as green transportation and photovoltaic power generation, with good application prospects. With the rapid development of materials science, many new materials have been used for the processing and manufacturing of sports equipment and equipment. They have a promoting effect on protecting athlete safety, improving sports experience, and improving competitive performance. As the official supplier of the Hangzhou Asian Games, Mount Taishan Sports Industry Group Co., Ltd., Jiangsu Jinling Sports Equipment Co., Ltd., Hangzhou Flying Eagle Yacht Co., Ltd., Hangzhou Kanghua Yacht Co., Ltd. and other enterprises have provided sports equipment and service guarantee for the event. There are many innovative applications of new materials in these sports equipment. Carbon fiber is a general term for a type of fiber with a carbon content exceeding 95%, which has very high specific modulus and strength
