Frontier new materials such as "Chang'e Steel" for deep space exploration, glass that continues to generate electricity in low light, and bio-based new materials made from straw...New materials are both strategic and fundamental industries, and they also serve as an important support for green development. At the Third International New Materials Industry Conference held in Bengbu, Anhui Province, a variety of new materials and new technologies were showcased, presenting new scenarios, new tracks, and new trends in the new materials industry from multiple dimensions, sketching out a green and low-carbon new prospect.
At the exhibition venue, a "miniature" model of the Chang'e 4 lunar probe attracted quite a crowd of onlookers.

When the Chang'e-4 probe landed on the moon, its 'legs' faced immense instantaneous impact forces, demanding high strength and toughness from the materials. Overcoming numerous challenges, the team independently developed 'Chang'e Steel', a material that boasts both high strength and high plasticity, thus solving the 'choke point' problem of landing materials for China's deep space probes. A member of the Special Aerospace Metal Materials Team from the Solid Physics Institute of the Hefei Institute of Physical Science of the Chinese Academy of Sciences proudly told reporters that, as an efficient energy-absorbing alloy material, the "most rigid yet most flexible" Chang'e Steel has significant advantages in many fields. It not only serves the "great power's heavy equipment" but will also play a huge role in the green transformation of living and production methods in the future.
Under the "Dual Carbon" goals, it is imperative to reduce over-reliance on fossil resources and develop low-carbon and environmentally friendly biobased new materials.
At the exhibition, Anhui Fengyuan Group Co., Ltd. showcased a range of products made from corn and straw, including beautiful apparel, innovative children's tableware, and PLA eco-friendly wall panels, which revolutionized attendees' perceptions of biobased new materials.
"We continue to enhance technological innovation, having mastered the core preparation process of polylactic acid derived from straw, and have established the entire technological chain from 'straw—sugar production—polylactic acid—product application.' An annual 15,000-ton straw sugar industrial demonstration plant has been put into operation," said Chen Liping, Deputy General Manager of Anhui Fengyuan Group Co., Ltd. "Through cooperation in industry, academia, and research, the company is continuously expanding the application scenarios of its products and extending the industrial chain."
As the new generation of information technology, new energy, and intelligent manufacturing industries rapidly develop, new materials and new technologies are accelerating their integration and innovation, unleashing a powerful new momentum from the green new engine.
"This engine blade utilizes a new ceramic-aluminum material. Compared to titanium alloy blades, it boasts high strength, toughness, and fatigue resistance, capable of accommodating greater altitudes and speeds. It holds vast potential applications in aerospace, automotive lightweighting, and other fields," said a relevant official from the Shanghai Jiao Tong University Anhui (Huaibei) Ceramic-Aluminum New Material Research Institute. In the future, as ceramic-aluminum materials evolve and production technologies improve, more new avenues for green development will be expanded.
On the brand-new photovoltaic carport, sheets of copper indium gallium selenide solar glass shimmer in the early winter sun, continuously providing the participants, new energy vehicle owners, with a "green energy" supply. Wu Zhongchao, Assistant General Manager of the Bengbu Power Supply Company under the Anhui Power Grid Co., Ltd., told the reporter that relying on new materials and technologies, the entire conference used low-carbon and environmentally friendly clean "green electricity."
"New material iterations and innovations are advancing rapidly, offering vast imaginative space for the green transformation of the energy and power systems." Wu Zhongchao told the reporter, "They are closely collaborating with the China National Building Materials Group Corporation's Glass New Material Research Institute to jointly promote the innovative application of new materials and technologies such as copper indium gallium selenide photovoltaic glass in more scenarios like the integrated energy demonstration projects for source-grid-load-storage charging, and green buildings."
Academician Gan Yong of the Chinese Academy of Engineering said, with the rapid development of the global high-tech industry, the continuous upgrading of manufacturing, and the growing demand for sustainable development, the need for new materials will be increasingly intense. The products, technologies, and models of new materials will continuously evolve, guiding the technological and industrial transformation of the world.
