Heat treatment induces chemical changes and silica sol penetration in wood for properties improvement: hydrophobicity, thermal stability, and surface hardness

Jun Jiang et al.

Summary: Thermal modification can be used as a pretreatment method to promote the impregnation of silica sol in wood, improving its resistance to moisture, hydrophobicity, and dimensional stability. This is achieved through the creation of additional channels and spaces due to the presence of micro-cracks and enlarged pore size, allowing for better silica transportation and deposition in the wood matrix.

In Situ Construction of Thermotropic Shape Memory Polymer in Wood for Enhancing Its Dimensional Stability

Wenhao Zhang et al.

Summary: This study proposes a novel strategy to stabilize wood by constructing a thermotropic shape memory polymer (SMP) inside wood. The presence of the SMP significantly enhances the dimensional stability of wood and reduces cracks. The desirable shape recovery abilities of the SMP under heating-cooling cycles are considered to be the main reasons for wood dimensional stabilization.

Performance improvement of poplar wood based on the synergies of furfurylation and polyethylene glycol impregnation

Tiantian Yang et al.

Summary: This study successfully improved the dimensional stability and mechanical strength of wood by vacuum impregnation of biomass-derived furfuryl alcohol and polyethylene glycol. The furfural resin and PEG were distributed in the wood and could reduce wood porosity, improve wood hydrophobicity and dimensional stability. The furfural resin helped to fix PEG in wood and reduced PEG leaching. These findings are of great significance for enhancing the application value of fast-growing wood.

Thermally resistant, mechanically stable, and processable triphenylamine-based hyperbranched copolyimides

Naila Khalid et al.

Summary: A new trifunctional, triamine compound was successfully synthesized through N-arylation in the presence of cesium fluoride and catalytic reduction, leading to the synthesis of a series of aromatic tree-shaped hyperbranched copolyimides (HBPIs) with good thermal stability and mechanical properties. These HBPIs are suggested for future use as thermally resistant, protective coatings for various devices and outdoor environments.

Experimental study on the penetration characteristics of leaking molten salt in the thermal insulation layer of aluminum silicate fiber

Yun Wang et al.

Summary: The study investigates the penetration and diffusion of leaking molten salt in an aluminum silicate fiber thermal insulation layer. Results show that a higher flow rate of molten salt leads to less penetration time and leaked mass, and as temperature and thickness increase, penetration time becomes longer and leaked mass becomes greater at a lower flow rate.
