“…Our research group has also made some good progresses in the modi cation and preparation of biobased phenolic resin, and the modi ed phenolic resin has been signi cantly improved in mechanical properties and thermal properties. By step-by-step polymerization method, with tung oil, linseed oil and lignin as modi ers, xu et al [40] successfully prepared tung oil-modi ed lignin-based phenolic resin (T-LPF) and linseed oil modi ed lignin-based phenolic resin (L-LPF). The introduction of tung oil and linseed oil can reduce the vulcanization activity and increase the vulcanization peak temperature.…”

“…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.

“…9 The ester bond and conjugated triple bond of tung oil provide numerous active sites for further modification and polymerization. A variety of polymeric materials have been prepared from tung oil, especially in the field of thermosetting resins, such as acrylic resins, 10 phenolic resin, 11 and epoxy resin. 12 Traditional thermosetting resins exhibit excellent mechanical properties, corrosion resistance, and heat resistance.…”

In order to reduce the overdependence on petroleum-based products, the preparation of functional polymers with renewable resources has become a research hotspot. In this study, tung oil, extracted from tung tree seeds, was introduced to the synthesis of tung maleic anhydride (TOMA) and epoxidized tung oil ethanolamides (ETOE) via a simple modification of the conjugated double bonds and ester bonds of tung oil, and then tung oil-based vitrimers (PETVs) based on a dynamic hydroxyl ester exchange reaction were prepared with different ratios of ETOE to TOMA. Due to the presence of abundant hydroxyl esters and flexible aliphatic long chains, PETVs showed a fast and excellent self-healing performance, and their repair efficiency reached 94.7% at 160 °C for 10 min without any catalyst. In addition, PETVs exhibited excellent mechanical properties, alkali degradability, shape memory properties, and recyclability. Degradation experiments indicated that PETVs could be completely hydrolyzed to small-molecule substances in alkaline solutions. PETV/MWCNT composites (PMs) with excellent electrical and thermal conductivity exhibited rapid self-healing ability under the conditions of electrical, infrared radiation, and heating. Compared to conventional petroleum-based thermoset polymers, PETVs with the advantages of environmental friendliness and sustainability could provide a practical strategy to prepare high-performance vitrimers from renewable materials.
