Ultra-high space utilization of wood/phenolic resin-derived thick ...
2024年3月15日 · Herein, a series of wood/phenolic resin composite materials were successfully prepared in a high concentration potassium hydroxide solution. The three-dimensional structure of the phenolic resin material is effectively coupled with the wood, greatly enhancing the spatial utilization and loading of active materials in wood-derived thick electrodes.
Bonding wood with uncondensed lignins as adhesives | Nature
2023年8月8日 · Researchers in academia and industry have long aimed to synthesize lignin–phenol–formaldehyde resin adhesives using biomass-derived lignin, a phenolic polymer that can be used to substitute ...
A new strategy for the preparation of wood-epoxy resin …
2024年3月15日 · In this study, we proposed a simple strategy to directly convert wood into high-performance composites by controlling wood surface penetration through resin pre-curing. A slight amount of resin used was sufficient to penetrate the wood surfaces, and the weight percent gain (WPG) of 11.45 %.
A multifunctional lignin-based composite ultra-adhesive for wood ...
2023年11月9日 · Phenolic resin adhesives are usually synthesized using phenol and formaldehyde. Both of them are fossil-based and the resins are not biodegradable. Replacing them with whole biomass-based lignin and furfural is attractive.
Wood Composites and Their Polymer Binders - MDPI
2020年5月13日 · Particleboard: A flat hot-pressed wood composite panel composed of randomly oriented wood chips bonded by hot-pressing by using thermosetting adhesive resins, mainly urea–formaldehyde (UF), melamine–urea–formaldehyde (MUF), phenolic resins (PF and TF), and isocyanates (pMDI). The board is generally composed of three distinct layers, the ...
Improving the properties of phenol-lignin-glyoxal as a wood
2022年12月5日 · Phenol-formaldehyde (PF) resins are one of the most important types of wood adhesive for wood panel manufacturing. The advantages of PF resins as a wood adhesive have been reported by several researchers (e.g., Moubarik et al. 2009; Younesi-Kordkheili 2019; Pizzi and Mittal 2011).
Wood-Based Phenolic Composites - SpringerLink
2020年11月10日 · A wood-based phenolic composite can be defined as a composites material mainly composed of wood elements and phenolic resins as adhesives. More recently wood has also been combined with thermoplastic polymers to make wood-polymer composites (WPC) by using compression, extrusion and injection moulding methods.
Phenolic resin filled wood-derived hierarchically porous carbon ...
5 天之前 · Low space utilization of wood-based electrodes seriously restricts its practical applications. In this paper, a wood/phenolic resin composite was designed, which can effectively enhance the space utilization of wood and ensure a hierarchical porous structure.
Synthesis of Biobased Novolac Phenol–Formaldehyde Wood …
2021年8月10日 · This study provides a comparative approach for phenolic sources derived from biorefinery processes to produce biobased phenol−formaldehyde resin adhesive for wood bonding.
(PDF) Wood Composites and Their Polymer Binders
2020年5月13日 · This review presents first, rather succinctly, what are the important points to look out for when preparing good wood composites, the main types of wood composites manufactured industrially,...
