Recently, a research team led by Prof. YU Shuhong from the University of Science and Technology of China (USTC) demonstrate a novel strategy for large-scale fabrication of a family of bioinspired polymeric woods with similar polyphenol matrix materials, wood-like cellular microstructures, and outstanding comprehensive performance by a self-assembly and thermocuring process of traditional resins (phenolic resin and melamine resin). This work was published on Science Advances entitled as Bioinspired polymeric woods on August 10th (Science Advances 2018, 4, eaat7223).
It illustrates how artificial woods are formed in molecular scale and details.
The liquid thermoset resins were firstly unidirectionally frozen to prepare a green body with the cellular structure, followed by the subsequent thermocuring to get the artificial polymeric woods. The artificial woods bear a close resemblance to natural woods in the mesoscale cellular structures, and exhibit well controllability in the pore size and wall thickness. Benefiting from the starting aqueous solution, it also represents a green approach to prepare multifunctional artificial woods by compositing various nanomaterials, such as cellulose nanofibers and graphene oxide.
This novel strategy provides a new and powerful route to fabricate and engineer a wide range of high-performance biomimetic engineering composite materials with desirable multifunctionality and advantages over the traditional counterparts, which will have broad applications in many technical fields.
On May 11, the Nature Publishing Group released Nature Publishing Index 2010 China, remarking “a dramatic rise in the quality of research being published by China”. University of Science and Technology of China is ranked 3rd of TOP 10 Institutions in Index 2010 China.
