a new strategy for large-scale fabrication of bio-inspired artificial
wood that manifested lightweight and high-strength properties with the
mechanical strength comparable to that of natural wood.
A study published on Friday in the journal Science Advances
described the high-performance polymeric materials with wood-like
A research team led by Yu Shuhong from the University of Science
and Technology of China (USTC) transformed traditional phenolic resin
and melamine resin into the artificial wood-like materials by
self-assembly and the thermocuring process.
Their strategy provided a new route to fabricate and engineer a
wide range of high-performance biomimetic engineering composite
materials with desirable multiple functions and advantages over the
traditional counterparts, having broad potential applications in many
The liquid thermoset resins were first "unidirectionally" frozen
to prepare a "green body" with the cellular structure, followed by the
subsequent thermocuring to get the artificial polymeric woods. They are
highly controllable in pore size and wall thickness.
Starting from aqueous solution, the strategy also represented a
green approach to prepare multifunctional artificial woods by
compositing various nanomaterials, such as cellulose nanofibers and
graphene oxide, according to the study.
Compared with natural woods, the artificial woods have better
corrosion resistance to water and acid with no decrease in mechanical
properties. They also have better thermal insulation and fire retardancy.
The artificial polymeric woods stand out from other engineering
materials such as cellular ceramic materials and aerogels in terms of
specific strength and thermal insulation properties.
As a kind of biomimetic engineering material, this new family of
bio-inspired polymeric woods is supposed to replace the natural wood
when used in harsh environments, Yu told Xinhua.
