Nanohybrid fibers play an important role in the medical field and the industry has good development prospects

Nanohybrid fiber is a product of the combination of nanofibers and composite materials. It has the characteristics of large specific surface area of ​​nanofibers and excellent mechanical and chemical properties of composite materials. It is a new material with excellent comprehensive properties. According to the “2021-2025 Nano Hybrid Fiber Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center, Nanohybrid fibers can be used in biosensing, bioimaging, medical protection, tissue repair and other fields, and are of great significance to improving medical technology.

Nanohybrid fibers include three categories: inorganic nanohybrid fibers, organic nanohybrid fibers, and organic-inorganic nanohybrid fibers. Polypeptide nanofibers and high molecular polymers (such as polyethylene, polyimide, etc.) can be used , metal nanoparticles, graphene, carbon nanotubes, quantum dots and other materials. Among them, bio-based nano-hybrid fibers and nano-hybrid fibers with good biocompatibility can be used in the medical field, and usually require It has excellent antibacterial and antiviral functions.

From the perspective of nanohybrid fiber research, Donghua University is a university with rapid research progress in the field of nanohybrid fibers in my country. In 2018, a team from the School of Materials Science and Engineering of Donghua University introduced NH2-MWCNTs (aminated multi-walled carbon nanotubes) into a PI (polyimide) matrix using an in-situ polymerization method and prepared it using a two-step wet spinning process. A series of NH2-MWCNTs/PI composite fibers (carbon nanotube/polyimide composite fibers) were developed. This new material can improve the mechanical, thermal and other properties of traditional PI to meet the needs of high-tech industries.

From the perspective of the industrialization development of nano-hybrid fibers, Meida’s “Nano-Hybrid Technology and Application in Functional Polyamide 6 Fiber” project won the first prize of the Guangdong Provincial Science and Technology Award. This technology focuses on realizing the full realization of The company has achieved industrialized production in 2018 for the production and industrial application of single-functional and composite-functional fibers such as matting, cooling, and antibacterial fibers.

From the perspective of nanohybrid fiber policy, in the “Nano Frontier” key project of my country’s “14th Five-Year Plan” national key research and development plan, nanohybrid fibers for diagnosis and treatment, organ repair, and in vitro protection are included. It is proposed to be based on human tissue and Material interaction mechanism to construct multi-level, multi-component and multi-structure nano-hybrid fiber materials; research through functional integrated bionic design to obtain fiber aggregates with functions such as enhanced diagnosis and treatment, tissue repair, and in vitro protection.

Industry analysts said that my country’s medical technology continues to advance, residents’ medical expenditures continue to rise, and the market continues to demand high-performance medical materials. Growth; from the perspective of policies, scientific research progress, and industrialization development, the technical strength of my country’s nanohybrid fiber industry continues to improve, and the policy environment continues to optimize.
