A novel bio-epoxy resin, TPEU-EP, was developed. It possesses good intrinsic flame retardancy, low smoke production, and excellent mechanical properties, showing high promise for application.
Harvesting biobased epoxy resins with improved thermomechanical properties (e.g., glass transition temperature Tg and storage modulus), mechanical dielectric similar even superior to that of bisphenol A resin (DGEBA) is vital many applications, yet remains a substantial challenge. Here we develop novel eugenol-based monomer (TEU-EP) branched topology very rich retention (80 wt %). TEU-EP can be well cured by 3,3′-diaminodiphenyl sulfone (33DDS) the resultant TEU-EP/33DDS system considered as...
Recent years have witnessed significant advances in biobased epoxy resins to replace their petroleum-based counterparts, especially diglycidyl ether of bisphenol A type resin (DGEBA). However, for meeting a great variety the requirements, long-standing challenges include environmentally friendly preparation with few toxic byproducts and improving properties. Herein, we report facile method synthesize new silicone-bridged difunctional monomers high yield. They are derived from naturally...
Aiming to develop a multi-functional flame retardant for epoxy resins, novel bio-based eugenol derivative (SIEPDP) was synthesized, and used modify Mg–Al layered double hydroxide (SIEPDP-LDH). This modified SIEPDP-LDH as nanoflame-retardant bisphenol resins compared with unmodified pristine LDH.
Waterborne superhydrophobic coatings have attracted tremendous attention recently, but their practical applications are severely limited by hydrophobic instability and poor mechanical durability. Herein, a novel robust waterborne PTFE-CP&MgO-AOP coating was successfully fabricated reinforcing composite interfaces. Combined with the self-polymerization of dopamine in situ grown MgO, CNTs-polydopamine&MgO (CP&MgO) particles improved interfacial compatibility were obtained. Through...
Antibacterial materials are preferable for water treatment a medical applications. In the present study, to improve antimicrobial performance of flexible polyurethane (PU) foams, copper nanoparticles were in situ generated. The Cu formed on surface cell walls with sizes 100–130 nm, and exhibited high affinity PU matrix. Although structure nanocomposite foams was not greatly influenced, open content decreased slightly from 97.42 96.64%. bound metal could strengthen skeleton improved...
Abstract Leakage is one of the most serious challenges for safe production high‐pressure gas wells its high risks, including abnormal annular pressure, natural accumulation, and environment pollution, but available methods can hardly accurately measure leakage type depth, which are key parameters rigless repair risk assessment. Therefore, this paper proposes a method to based on characteristics, combines qualitative quantitative measurement together. Qualitative considers tubing liquid...
By using resin transfer molding (RTM) technology, carbon fiber (CF) reinforced epoxy composites (CF/Epoxy, CF/PES/Epoxy, and CF/PES-MWCNT/Epoxy) are prepared. CF is the fiber, Epoxy matrix, PES-MWCNT multiwall nanotubes doped polyethersulfone film. Their fire behavior systematically studied according to limiting oxygen index (LOI), vertical burning test (UL94), cone calorimeter (CCT). thermal degradation process, kinetics, flame retardant mechanism investigated from thermogravimetric...
With wide application of natural fibers in polymer composites, improvements their flame retardancy, water absorption, and electrical resistance become an urgent need. To this end, 4.5 wt % layered double hydroxide (LDH) is introduced into sisal fiber reinforced biobased silicone modified phenolic composites. The composites optimally shows 60% reduction total heat release (20.2 MJ/m2) compared to the without LDH. In addition, modifier TDS incorporated resins (SPF), further reduce absorption...
To develop biobased polyurethanes (PUs) via a less hazardous, nonisocyanate route, herein we synthesize series of polyhydroxyurethanes (PHUs) by reacting new cyclocarbonate (derived from renewable diphenolic acid and carbon dioxide) with ethylenediamine (EDA), diethylenetriamine (DETA), isophoronediamine (IPDA), corresponding to PHU-EDA, PHU-DETA, PHU-IPDA, respectively. Their molecular structures are identified 1H NMR FTIR analyses. Gel permeation chromatography (GPC) analysis shows that...
