How can bio d materials become the main force of new materials?
To speed up technological progress and industrial development
Bio d material is a kind of polymer material which can be obtained by biotransformation of renewable materials and then further polymerized. Bio d materials include bio d platform compounds, bio plastics, functional sugar products, wood plastic composite materials, etc. it has the characteristics of green, environment-friendly, renewable raw materials and biodegradability that traditional polymer materials do not have. Its products not only include daily necessities, such as packaging materials and disposable daily necessities, but also biomedical materials such as high-tech and high added value drug control release materials, bone fixation materials and human tissue repair materials.
The research and promotion of bio d composite materials have gradually spread from European and American countries to the world. According to the latest report released in 2014 by Freedonia, a famous market research institution in the world, the market value of WPC in the United States will reach 5.5 billion US dollars in 2018.
It is understood that many colleges and universities, scientific research institutes and key enterprises in China have made distinctive research results or industrial technology achievements in bio d materials.
Previously, Chen Xingliang, vice president and Secretary General of China forestry society, said at the Symposium on bio d composite materials sponsored by China forestry society that the main development direction of international new material industry is to develop environmentally friendly bio d composite materials by using abundant biomass resources and to replace plastics, steel, cement and other materials to the maximum extent.
However, Tan Tianwei, academician of the Chinese Academy of engineering, once pointed out in his research that although great progress has been made in the research and industrialization of bio d materials in China, there is still a certain gap compared with developed countries such as the United States, Europe, Japan, etc., mainly because the technology is not mature enough, the product performance cannot fully meet various consumer needs, and the cost is too high to be compared with oil-d products. Product competition, etc.
"On the basis of learning from foreign experience, China should deepen the research and development of key technologies for industrialization and accelerate technological progress, so as to have all kinds of innovative products with independent intellectual property rights, so as to promote the overall level of China's bio d material industry forward." Tan said.
At present, China has become the world's largest producer and exporter of wood plastic composite materials, with a large number of manufacturing enterprises. However, compared with the large-scale production of European and American enterprises, they still do not have competitive advantages, and enterprises need to be further bigger and stronger.
