“…The remained water-soluble vinyl monomers in the treated d -cellobiose and EHL have been removed before analysis. The signals in the NMR spectra of the samples were assigned according to previous articles. − The 1 H NMR spectra of untreated and treated d -cellobiose are shown in Figure a, d, respectively. The peak at 4.97 ppm was corresponded to −OH (C 2′ ) in d -cellobiose.…”

The accomplishment of lightweight reinforcement of wood through an environmentally friendly approach has been seen as a tough nut to crack for a long time. In this study, a novel method inserting water-soluble vinyl monomers into wood cell walls followed by in situ polymerization was proposed. The distributions of the modifiers in the wood cell walls and the graft mechanism between water-soluble vinyl monomers and wood cell wall components were thoroughly investigated. Results indicated that the water-soluble vinyl monomers could effectively permeate into the wood cell walls and connected with the hydroxyl groups of the lignin and polysaccharides via covalent bonds. The lumen of the wood remained unfilled during the modification process, and just a 40% weight gain was achieved. However, a 68.37% antiswelling efficiency was achieved after a water-soluble vinyl monomer treatment under the optimized condition (when 20 wt % of NMA was coadded). The modulus of rupture and modulus of elasticity of the corresponding material increased 20.2% and 38.0%, respectively, compared with those of the untreated one.

As the only renewable resource among the four basic materials (steel, cement, plastic, wood), wood itself and wood products have a “low carbon” value and play an important role in storing carbon. The moisture absorption and expansion properties of wood limit its application scope and shorten its service life. To enhance the mechanical and physical properties of fast-growing poplars, an eco-friendly modification procedure has been used. This was accomplished by the in situ modification of wood cell walls by vacuum pressure impregnation with a reaction of water-soluble 2-hydroxyethyl methacrylate (HEMA) and N,N’-methylenebis(acrylamide) (MBA). The anti-swelling efficiency of HEMA/MBA-treated wood was improved (up to 61.13%), whereas HEMA/MBA-treated wood presented a lower weight-gain rate (WG) and water-absorption rate (WAR). It was observed that the modulus of elasticity, hardness, density, and other properties of modified wood had improved significantly, as indicated by XRD analysis. Modifiers diffuse primarily within cell walls and cell interstices of wood, causing crosslinks between the modifiers and the cell walls, reducing its hydroxyl content and blocking the channels for water movement, thereby enhancing its physical properties. This result can be obtained by scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDX), Nitrogen adsorption test imaging ATR-FTIR (Attenuated total reflection-Fourier-Transform Infrared) Spectroscopy, and nuclear magnetic resonance (NMR) and Nitrogen adsorption test. Overall, this straightforward, high-performance modification method is crucial for maximizing wood’s efficiency and the sustainable development of human society.

“…At present, the conventional acrylamide polymer under the condition of high temperature and high salt, easy hydrolysis and occur thermal degradation reaction, lead to the solution viscosity decreased with increasing temperature and salt concentration, thereby limiting its applications. However, n ‐methylol acrylamide (HAM), which is a water‐soluble bifunctional nonionic monomer with polymerizable vinyl and crosslinkable methylol groups, has first introduced as FLA monomer . As we can see, the HAM has a similar structure to acrylamide (AM), which has a widespread application in FLAs.…”

A terpolymer comprising of sodium styrene sulfonate (SSS), n-methylol acrylamide (HAM), and acrylic acid (AA) was synthesized by aqueous free radical copolymerization and evaluated as fluid loss additive (FLA) in oil well cement. In this article, HAM is first introduced in the preparation of FLA as an environment-friendly monomer, which effectively improves the adhesion and fluid loss control of the terpolymer. The experimental synthesis conditions were optimized by orthogonal experiments. The molecule weight of the terpolymer was determined by gel permeation chromatography. The molecule structure of the synthesized terpolymer was verified by Xray photoelectron spectroscopy and Fourier transformer infrared spectrum. The thermal stability of the synthesized terpolymer was tested by thermogravimetry (TG). The structure of the terpolymer aqueous solution was observed by scanning electron microscope. The results show that SSS/HAM/AA has an excellent thermal resistant. The thermal degradation is not obvious before 295.2 8C. Furthermore, the microstructure of SSS/HAM/AA in water conducive to good fluid loss control ability. When the dosage of SSS/HAM/AA is up to 2.0% in fresh water cement slurry, the filtration loss [FL (HTHP) ] can be controlled within 50 mL at 90-150 8C. SSS/HAM/AA has an excellent property of reducing filtration loss.
