“…According to the FTIR spectrum of lignin (marked L), before modification, the skeleton vibration of aromatic ring in the lignin appeared at 1573, 1414 cm −1 [ 33 ]. The absorption peak at 1215 cm −1 ( Figure 3 (a1)) was related to the stretching vibrations of the C–O bonds, and the absorption peaks (1130, 1050 cm −1 ) were mainly caused by the stretching vibrations of C–O–C bonds [ 34 ]. After modification, the phosphate groups were introduced to lignin to form PL by the substitution reaction of the –CH 2 Cl of the intermediate (3-chloro-2-hydroxypropyl phosphate) and the active sites of lignin.…”

Construction of CNC@SiO2@PL Based Superhydrophobic Wood with Excellent Abrasion Resistance Based on Nanoindentation Analysis and Good UV Resistance

Construction of superhydrophobic woods with high abrasion resistance is still a major challenge, and micro analysis for abrasion resistance is scarce. To improve these issues, cellulose nanocrystals (CNC)@SiO2@phosphorylated lignin (PL) rods were prepared by SiO2 in situ generated on CNC, and then the modified lignin attached to the CNC@SiO2 rods surface. Subsequently, the superhydrophobic coating was constructed using hydrophobic modified CNC@SiO2@PL rods as the main structural substance by simple spraying or rolling them onto wood surfaces, and both polydimethylsiloxane (PDMS) and epoxy resin were used as the adhesives. The resulting coating had excellent superhydrophobic properties with a water contact angle (WCA) of 157.4° and a slide angle (SA) of 6°. The introduced PL could enhance ultraviolet (UV) resistance of the coating due to the presence of these groups that absorbed UV light in lignin. In the abrasion resistance test, compared with the SiO2/PL coating, the abrasion resistance of the one with CNC was much higher, suggesting that CNC could improve the abrasion resistance of the coating due to its high crystallinity and excellent mechanical strength. The coating with PDMS performed better than the one with epoxy resin because the soft surface could offset part of the external impact by deformation in the abrasion process. This was also consistent with the results of the nanoindentation (NI) tests. In view of the simple preparation and good performance, this superhydrophobic wood will have broad application potential.

“…Meanwhile, petroleum-based epoxy resins are facing serious environmental and sustainability problems due to their nonrenewability. Biobased epoxy resins originating from renewable resources, such as vegetable oils, , lignin, − vanillin, − furan, , are beneficial for establishing a stainable low-carbon society. Currently, many biobased epoxy resins are reported with excellent performance, for instance, higher glass transition temperature ,, and better mechanical properties ,, compared to commercial bisphenol A epoxy resin (DGEBA), and intrinsic flame retardancy. ,,, The outstanding performances of biobased epoxy resins make sure to replace DGEBA in the conventional applied fields.…”

Biobased epoxy resins have received widespread attention due to their substitution for petroleum-based ones in conventional fields but are rarely reported in functional materials. Herein, a biobased epoxy resin with inherently deep-UV photodegradability was reported. The strategy was based on the [2 + 2] photocycloaddition of trans-cinnamic acid, a renewable resource, to generate a cyclobutane structure in the backbone, which was cleaved upon <280 nm light irradiation. The as-prepared epoxy resin showed high thermal stability and good thermomechanical properties. Meanwhile, owing to the ozonosphere blocking the UV light with a wavelength of <290 nm, the stability of this epoxy resin was guaranteed under a normal environment. When exposed to deep-UV light irradiation, degradation occurred. The degradation mechanism study demonstrated that molecular packing (crystalline/amorphism) was important in determining its degradability. Based on its photoresponsive features, the feasibility of this epoxy resin in the fields of a positive photoresist and anticounterfeiting was well explored. This work provides an attractive strategy for developing biobased epoxy resins to expand their potential application fields.

“…[12][13][14] In this regard, the biobased vanillin-derived epoxy coating was proposed to improve hydrophobicity, making them ideal for TENG applications. 15 This epoxy resin is an environmentally friendly substitute for commercial synthetic resins, which have alarming environmental threats associated with the increasing usage of petroleum-based components. Thus, the coating of CNF films with biobased epoxy results in a novel green composite with excellent TENG properties.…”

The petroleum-based derived materials are used in industrial applications due to their specific properties. However, they are increasing environmental concerns because they produce toxic gases when disposed of and burned [1, 2]. Thus, biomass-derived epoxy resins have gained significant attention due to their low-cost, easy synthetic route, and environmentally friendly. CNF can be a promising approach for the future generation to design all-green materials with bio-mass-derived resins for various applications [3, 4]. This research aims to explore the strategies for hydrophilic CNF film to make it useable for high-performance applications. In this regard, the bio-based vanillin-derived epoxy resin was proposed to improve hydrophobicity of CNF film, making them ideal for TENG applications.
