“…Depending on the alkaline or acidic conditions employed, the reaction occurs between the deprotonated phenol structure and the N , N -dialkylaminomethanol or between the phenolic lignin and the N , N -dialkyl(methylene) ammonium ion, respectively, both leading to the same final product . Qiu et al prepared diethylamine grafted lignin (DL) through a facile Mannich modification of soda lignin. FTIR, 1 H NMR, and 2D-HSQC measurements confirm the formation of aminated lignin.…”

“…Xue et al 63 and Barana et al 64 reported similar routes for the preparation of lignin−silica hybrids, which used rice husk as the raw material due to the abundance of both lignin and silica within the rice husk; however, a prior acid pretreatment is needed to remove the polysaccharide components. Qiu et al 44 prepared lignin−SiO 2 hybrids (DLSi) via a one-pot in situ assembly of diethylamine grafted lignin (DL) and SiO 2 . The resultant hybrids present as homogeneous nanospheres with well-integrated DL and SiO 2 components and significantly reduced polarity.…”

“…SBR/ENR composites with aldehyde-modified lignin show a superior wet skid resistance as well as low rolling resistance. Qiu et al 44 prepared NR composites filled with DLSi/CB of 10/40 phr, which showed excellent mechanical properties and reduced rolling resistance. These results are directly related to the moderate filler−filler interaction between CB and DLSi particles and the shielding effect of DLSi on the CB filler−filler networks, similar to the classic CB and silica dual-filler system for radical tires.…”

The biomass lignin is the only large-volume renewable feedstock that is composed of aromatics but has been largely underutilized and is sought for valorization as a value-added material. Recent research has highlighted lignin as a promising alternative to traditional petrol-based reinforcements and functional additives for rubber composites. This review summarized the recent advances in the functionalization of lignin for a variety of rubber composites, as well as the compounding techniques for effectively dispersing lignin within the rubber matrix. Significant progress has been achieved in the development of high-performance and advanced functional rubber/lignin composites through carefully designing the structure of lignin-based additives and the optimization of interfacial morphologies. This Review discussed the effect of lignin on composite properties, including mechanical reinforcement, dynamic properties, antiaging performance, and oil resistance, and also the advanced stimuli-responsive performance in detail. A critical analysis for the future development of rubber/lignin composites is presented as concluding remarks.

“…Results demonstrated that the phosphate adsorption mechanism of Fe(III)-complexed lignin (Fe-CL) followed the complexation mechanism between Fe and phosphate on Fe-CL. Qiu et al [72] showed the reinforcing effect of lignin-based polymer on natural rubber (NR). They first prepared diethylamine grafted lignin (DL) through Mannich modification, and then well assembled the SIO 2 and DL to the hybrid (DLSi) as homogeneous nanospheres.…”

As a major component of lignocellulosic biomass, lignin has lots of fascinating properties, such as regeneration, biocompatibility, antioxidant, hydrophilicity, unique aromatic structure, and various functional groups, which make them become interesting natural polymer raw material, and attracted more and more attention. In particular, the rich functional groups of lignin can be easily functionalized through various synthesis methods, which can endow lignin‐based polymers with new structure and function. These functional lignin‐based polymers are widely used in environmental remediation, smart hydrogel materials, catalysis, biomedical, etc. However, its various sources and types, the complex structure, relatively weak chemical reactivity, the unstable processing property, and few high value‐added products limited their practical applications. With the development of lignin varieties, modified reagent, synthesis methods, and polymerization process, many works had been published for the synthesis and application of lignin‐based polymers. In this review, the lignin isolation, modification strategies, polymerization method and process, and the promising applications were summarized and analyzed in recent years. Specially, the recent advances in the preparation of high excellent adsorbents from deconstructed lignin products are highlighted from the synthesis methods and adsorption mechanism perspective. Finally, we discussed these challenges in the green and controllable synthesis of lignin‐based polymers, and prospected their functional applications.

With the rapid development of transportation system, the safety, reliability, and durability of green tires play an important role in modern transportation. While for the material preparation, the poor dispersion ability of reinforced filler and the weak interfacial interactions with polymer matrix seriously restricted the further application in the green tire field. Meanwhile, avoiding the use of organic solvents is also an environmental issue that needs to be considered in the preparation process. Herein, water‐soluble 2‐mercapto‐1‐methylimidazole (MMI) functionalized graphene oxide (GO‐MMI) was obtained through a simple, green and one‐step hydrothermal method. Additionally, the modified graphene oxide/natural rubber composites (GO‐MMI/NR) with different GO‐MMI content were prepared by the latex coprecipitation approach. As a result, the modified GO‐MMI could be evenly dispersed in the NR matrix through the mechanical blending and the obtained GO‐MMI/NR composites possessed the good comprehensive properties after vulcanization. Specifically, the tensile strength (26.8 MPa), elongation at break (801%), low heat build‐up (6.2°C), Deutsches Institute for Normung (DIN) abrasion loss volume (71.31 mm3) and heat resistance index (162.1°C) were synchronic‐lifting when compared with the GO/NR composites. The results demonstrated that obtained GO‐MMI/NR composites owned the promising application for the industrial‐scale green tires.
