Phenolic resin filled wood-derived hierarchically porous carbon ...
5 天之前 · 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. The prepared balsa wood/phenolic resin composite-derived electrode obtained a high areal capacitance (8169 mF cm –2 ), which is 954 % of pure balsa wood-based electrode.
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.
Rapid increase in growth and productivity can aid invasions by a …
2016年8月2日 · To test the association between mean annual growth rates and chemical defences, we built three linear models for each naturalized population using non-volatile wood resin content, needle total phenolic content or wood total phenolic content as a dependent variable and MAG as an independent variable.
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.

Phenolation to Improve Hardwood Kraft Lignin for Wood …
2024年7月5日 · Resole-type phenol formaldehyde (PF) adhesive is commonly used in wood composites requiring durability and weather-proofness. However, PF adhesive is a petroleum-based product. The objective of this study is to transform the low-reactivity hardwood kraft lignin (KL) as the phenol substitute in the PF adhesive formulation by acidic phenolation.
Structure and basic properties of woodceramics made from phenolic …
2004年3月15日 · Woodceramics, a new kind of porous carbon materials, is usually fabricated by carbonizing wood or woody materials impregnated with phenolic resin or liquefied wood under vacuum at elevated temperatures of 300–2800 °C [1].
Effects of molecular weight and some other properties of resins on …
Biological resistance of PF (phenol formaldehyde)-resin treated woods were investigated in relation to the Mw (number-average molecular weight) and some other properties of resins. Seven resins, of which three (Mw: 369, 621, and 1, 143) and others (Mw: 383, 545, 791, and 991) supplied by two different manufacturers, were used for the treatments.
Phenolic resin-wood interaction - EurekaMag
Resin surface properties, wood wetting, and wood surface property alterations were examined with reference to the resin formulations and resin characteristics. The study found that the surface tension of phenol-formaldehyde resole resins varied with sodium hydroxide level, formaldehyde level, and molecular weight.
Biological resistance of phenolic resin-treated wood …
Decay resistance of resin-treated wood was better against Coriolus versicolor than against Tyromyces palustris, and was better for cedar and pine than for beech. Enhancement of termite resistance by boric acid was clearly shown in cedar and beech, particularly when the acid was mixed with PF resin.
