Latest Patents

One of Zhu's latest patents is for "Strong and tough structural wood materials, and methods for fabricating and use thereof." This invention involves a super strong and tough densified wood structure created by chemically treating cellulose-based natural wood material to partially remove lignin. The treated wood retains the lumina of the natural wood, with aligned cellulose nanofibers in the cell walls. The wood is then pressed in a direction that crosses the lumina, collapsing them and removing any residual fluid. This process results in entangled cell walls and hydrogen bonds between adjacent cellulose nanofibers, significantly improving the wood's strength and toughness. The densified wood can be further modified for various applications.

Another notable patent is for "Transparent wood composite, systems and method of fabrication." This innovation has led to the development of highly transparent wood composites with up to 92% light transmittance. The fabrication process includes lignin removal followed by index-matching polymer infiltration, preserving the naturally aligned nanoscale fibers. The thickness and optical transmittance of the composite can be tailored by controlling the initial wood substrate and selecting infiltrating polymers with different refractive indices. These transparent wood composites have applications in biodegradable electronics, optoelectronics, and energy-efficient building materials. Notably, coating the transparent wood composite layer on GaAs thin film solar cells has resulted in an 18% enhancement in energy conversion efficiency.
