Structure of hexagonal boron nitride (h-BN) is similar to that graphite before functionalization and exfoliation.
Polyurethane (PU) composites reinforced with graphene nanosheets (GNSs) were prepared by in situpolymerization. Graphene nanosheets, which derived from chemically reduced graphite oxide (GO) characterized solid-state 13C MAS NMR, XRD and FTIR. A morphological study showed that, due to the formation of chemical bonds, GNS was dispersed well PU matrix. With incorporation 2.0 wt% GNSs, tensile strength storage modulus increased 239% 202%, respectively. The nanocomposites displayed high...
Abstract Graphene‐based sheets that possess a unique nanostructure and variety of fascinating properties are appealing as promising nanoscale building blocks new composites. Herein, graphene oxide used the substrates for formation silver‐nanoparticle films. These films assembled on flexible can form stable suspensions in aqueous solutions. They also be easily processed, forming macroscopic with high reflectivity. Raman signals such hybrid increased by attached silver nanoparticles,...
Ni–Fe layered double hydroxide/graphene hybrids were synthesized by a one-pot in situ solvothermal route. X-ray diffraction and photoelectron spectroscopy analyses showed that the formation of hydroxide (Ni–Fe LDH) reduction graphene oxide occurred simultaneously during process. TGA results incorporation LDH significantly improved thermal stability graphene. Subsequently, LDH/graphene introduced into epoxy resins for reducing their fire hazard. With 2.0 wt% LDH/graphene, onset degradation...
Simultaneous reduction and surface functionalization of graphene oxide (GO) was realized by simple refluxing GO with octa-aminophenyl polyhedral oligomeric silsesquioxanes (OapPOSS) without the use any reducing agents. The presence OapPOSS made hydrophilic hydrophobic, as evidenced good dispersion OapPOSS-reduced (OapPOSS-rGO) in tetrahydrofuran solvent. structure OapPOSS-rGO confirmed XPS, FTIR TEM. A morphological study showed that, due to interfacial interaction between functionalized...
Aiming at developing highly efficient nano fire retardants and retarding epoxy resins, a series of functionalized layered double hydroxides (LDHs) based on multi-modifier system have been developed. These LDHs were used as novel flame-retardants for bisphenol resins compared with unmodified LDHs.
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.
A novel strategy based on functionalized graphene oxide (FGO)/phosphoramide oligomer flame retardant was developed to overcome the challenges of dispersion sheets in polymer matrix and ease burn-out under air atmosphere. Graphene (GO) modified by 4,4-diaminodiphenyl methane (DDM) then situ incorporated into phosphoramide oligomer, resulting a nanocomposite (FRs-FGO) containing exfoliated graphene. Subsequently, polypropylene (PP) simultaneously compatilized with PP-grafted maleic anhydride....
A biobased flame retardant toughening agent, phosphaphenanthrene groups-containing triscardanyl phosphate (PTCP), was successfully synthesized via debydrochlorination, epoxidation and ring opening reaction from renewable resource cardanol. The chemical structure of PTCP confirmed by the proton phosphorus nuclear magnetic resonance. Epoxy resins (EPs) with different contents were prepared through a simple mixing method. Thermogravimetric analysis results indicated that earlier degradation...
A polyphosphamide (PPA) was synthesized and covalently grafted onto the surface of graphene nanosheets (GNSs) to obtain a novel flame retardant, PPA-g-GNS, subsequently PPA-g-GNS incorporated into epoxy resins (EPs) enhance fire resistance. The chemical structures morphology precursors target product were confirmed using 1H-NMR spectroscopy, Fourier transform infrared spectroscopy atomic force microscopy. tensile results showed that mechanical strength modulus PPA-g-GNS/EP composite higher...
Abstract Two‐dimensional (2D) materials exhibit massive potential for research and development in the scientific world due to unique electrical, optical, thermal, mechanical properties. Particularly, they have received intensive attentions microwave absorption (MA) electromagnetic interference (EMI) shielding.

A biobased modifier (cardanol-BS) was successfully synthesized from renewable resource cardanol via the ring-opening of 1, 4-butane sultone (BS). Cardanol-BS modified layered double hydroxide (m-LDH) developed through a one-step coprecipitation method and subsequently incorporated into epoxy resins (EPs) with different loadings using combined technique three-roll mill ultrasonication. As comparison, pristine LDH/EP composite also prepared same procedure. The XRD result indicated that...
