“…After the reaction, the product was naturally cooled to room temperature and cleaned for 3 times in ultrasonic cleaner with absolute ethanol and deionized water, and the product and impurities were then separated by suction ltration with Buchner funnel. Finally, the product was dehydrated and dried in vacuum oven at 65°C for 48 h to obtain traditional PF [40][41] .…”

The preparation of green bio-based phenolic resin with high performance has far-reaching significance for sustainable development and is an important research direction for researchers in recent years. In this study, a novel resveratrol-modified lignin-based phenolic phenolic resin (R-LPF) with ultra-high Tg and improved mechanical properties was synthesized with biomass phenol of resveratrol and lignin as raw materials. The curing behaviors of phenolic resin (PF), lignin phenolic resin (LPF) and R-LPF were investigated. The thermal mechanical properties, thermal stability, comprehensive mechanical properties, frictional properties and morphology were systematically tested and analyzed. The results show that the highest Tg of the modified R-LPF reaches 346.2°C, which is much higher than that of traditional PF, and the thermal and mechanical properties of the novel R-LPF are also significantly improved. The Ts reaches 231.5°C, and the residual carbon rate reaches 66.2% at 800°C. The improved tensile strength, bending strength and impact strength are 28.72 ± 1.10 MPa, 57.58 ± 1.95 MPa and 3.14 ± 0.19 MPa, respectively. Compared with PF and LPF, the wear resistance is also significantly improved. Due to the rigid structure and high crosslinking density, the modified resin has excellent properties and provides broad application prospects in resin-based friction materials for the bioresource of resveratrol.

“…It also has better wear resistance and can be used as potential high-performance friction composite matrix. Qin et al [41] used daidzein and naringenin as biomass phenols to partially replace phenol, and successfully prepared daidzein modi ed phenolic resin (D-PF) and naringenin modi ed phenolic resin (N-PF) through one-step polymerization. The thermal stability, ablative resistance and mechanical properties of phenolic resin can be greatly improved by D-PF and N-PF with appropriate substitution ratio.…”

“…In recent years, due to the limited and unsustainable petrochemical resources and environmental pollution, sustainable development and green environment have become essential principles in the design of damping materials [21], [22]. As a typical biomass material, lignin is one of the rare renewable resources among aromatic compounds, and lignin can be used as substitute for phenol to prepare ligninbased phenolic resins (LPF) [23].…”

It is of interest to develop wide-temperature domain damped hydrophobic materials. In this paper, we designed incorporating bio-based phenolic resin into the IIR matrix and introducing dibenzyl fork acetone (DBA) into the main chain structure with sodium hydroxide activation to construct three-dimensional network. The added bio-based phenolic resin has reticulated structure blended with butyl rubber, combined with sodium hydride activation-modified IIR. The results show that sodium hydride activated modification of DBA is introduced into the main chain structure of IIR by infrared and 1H NMR analysis. The material hydrophobic is realized by the introduction of DBA with static water contact angle of 103.5°. The addition of 10phr lignin-based phenolic resin (LPF) is compatible with IIR, and the torque can reach 7.0N-m. The tensile elongation of the modified butyl rubber composite can reach 2400% with tensile strength up to 11.43 MPa, while the damping factor can reach 0.37 even at 70°C. The thermal stability of the composites is enhanced with mass retention rate of 28%. The bio-based PF/NaH activation-modified butyl rubber damping material has potential applications in damping hydrophobicity with wide temperature range.
