This review addresses the recent developments of processing cellulose nanocomposites, focusing on most used techniques, including solution casting, melt-processing thermoplastic nanocomposites and resin impregnation nanopapers using thermoset resins. Important such as partially dissolved nanocomposite foams reinforced with nanocellulose, well long continuous fibers or filaments, are also addressed. It is shown how research has rapidly increased during last 10 years, manufacturing techniques...
Using, urea, one of the cheapest chemicals and convenient deamination polycondensation (solvent-free, catalyst-free, one-pot, one-step) provides an industrially relevant environmentally benign synthesis branched polyurea. Inspired by structural analysis traditional resin adhesives, we hypothesized that higher cross-linking degree adhesive after curing, better bonding performance. Improving branching adhesives is key to improve their In this work, in order verify relationship between polymer...
We propose a new idea for facile and green synthesis of urea-based highly branched polymers (HBPs) using polyamines urea via deamination. More importantly, our strategy is to directly use the synthesized HBPs construct plywood. The would be further condensed solidified during hot pressing process, resulting in aldehyde-free wood adhesive with high bonding performance. In this work, water-soluble were by one-pot one-step polycondensations between (U) tris(2-aminoethyl)amine (TAEA), no...
The increasingly serious environmental problems make it urgent to develop a new type of sustainable green material which can degrade pollutants and monitor human health. However, the traditional preparation methods are frequently limited by tedious operations, high-energy consumption, massive pollution. Herein, we present facile method for MnO2 nanoflakes mediated macrocyclic molecule calix[8]arene. in situ grew on preformed gold nanoparticles, forming an impressive core–shell Au@MnO2...
Ambient temperature self-blowing mimosa tannin-based non-isocyanate polyurethane (NIPU) rigid foam was produced, based on a formulation of resin. A citric acid and glutaraldehyde mixture served as blowing agent used to provide foaming energy cross-link the tannin-derived products synthesize NIPU foams. Series foams containing different amount were prepared. The reaction mechanism investigated by Fourier Trasform InfraRed (FT-IR), Matrix Assisted Laser Desorption Ionization (MALDI-TOF) mass...
Application of epoxidized soybean oil (ESO) in the wood industry as an adhesive has been limited due to difficulty fast curing ESO. Due advantages urea-formaldehyde (UF) resin, like low cost, high molecular weight, rich functional groups, well self-curing property, cocuring ESO-UF adhesives were prepared by mixing UF with ESO different ratios (15–50%). Bonding performance tests indicated that balanced bonding strengths and formaldehyde emission level; especially, provided satisfactory water...
The structural changes during three-step synthesis of low-molar ratio urea–formaldehyde (UF) resin were tracked by quantitative 13C nuclear magnetic resonance (13C NMR) analysis and electrospray ionization-mass spectrometry (ESI–MS). Condensations that produced polymers found to be linked ether bonds in addition hydroxymethylation reactions at the first alkaline stage with a formaldehyde urea 2:1. Considerable formation branched methylene linkages, highest content among all condensed...
The compatibility issue between poly(lactic acid) (PLA) and tannin is a big challenge for preparing PLA/tannin biocomposites with enhanced properties. In this work, composites properties have been accomplished using an efficient one-step reactive extrusion method the help of methylene diphenyl diisocyanate (p-MDI) or 3-aminopropytriethoxysilane (APS). extent achieved via was evaluated by tensile, morphological, rheological, thermal obtained results indicated that adhesion promoters,...
