“…However, melamine, phenol, and other copolymerization modifiers are petrochemical products, which could cause serious environmental pollution and overload the resource burden as they are widely used [ 18 , 19 , 20 ]. The seriously environmental problems are against green and sustainable development [ 21 , 22 , 23 ]. The second problem is that: much flour or starch was used to adjust the initial viscosity and rheological behavior of the resin.…”

Low-cost urea formaldehyde resin (UF)/reactive halloysite nanotubes (HNTs) nanocomposite adhesive was prepared successfully via in situ polymerization. The HNTs were modified to improve its compatibility with polymer. The XRD and FTIR results showed that physical and chemical interaction between the HNTs and polymer resin influenced the structure of UF owing to the functional groups on the HNTs. It is found from SEM images that the modified HNTs could be dispersed uniformly in the resin and the nanocomposite particles were spherical. The performance experiment confirmed that thermal stability of nanocomposite increased largely, formaldehyde emission of UF wood adhesive reduced 62%, and water resistance of UF wood adhesive improved by 84%. Meanwhile, the content of HNTs on the nanocomposites could be up to 60 wt %. The mechanism of the nanocomposites based on the reactive HNTs was proposed. The approach of the preparation could supply an idea to prepare other polymer/clay nanocomposites.

“…As shown in Figure a, the high-resolution N 1s spectrum for NPC-0 was deconvoluted into five major peaks. The peaks at 398.4, 399.3, 400.1, 400.9, and 403.3 eV corresponded to pyridinic-N, metallic-N, pyrrolic-N, graphitic-N, and oxides-N, respectively. , Among them, pyridinic-N contributed to additional pseudocapacitance, and the graphitic-N could improve the conductivity. , Figure b shows the high-resolution C 1s spectrum of NPC-0, which could be mainly deconvoluted into five peaks. , The peak at 284.6 eV was assigned to the C–C bonds of sp 3 -hybridized carbon. The peak at 285.1 eV corresponded to the sp 2 -carbon containing nitrogen atoms (CN bond).…”

A novel self-assembling reduced graphene oxide-/ N-doped porous carbon (rGO/NPC) hydrogel electrode was successfully synthesized by in situ growth of zeolitic imidazolate framework (ZIF-67) nanoparticles on sodium carboxymethylcellulose (CMC) and a subsequent carbonization, followed by selfassembly with rGO through a simple hydrothermal process. The CMC serving as the biotemplate of ZIF-67 nanoparticles could effectively prevent their serious aggregation for fabricating NPC, which is efficiently doped with abundant nitrogen content that originates in ZIF-67. The introduction of rGO could improve the conductivity of the composite and directly used as a binder-free electrode for supercapacitors. The results show that the hydrogel electrode exhibited excellent electrochemical performance; it presented an improved capacitance of 190 F/g at 0.5 A/g. Further, a symmetric supercapacitor based on the hydrogel electrode was constructed, which possessed a superior energy density of 17.4 W h/ kg at a power density of 338 W/kg and 12 W h/kg at 3375 W/kg and long cycling stability (a retention of 87.1% after 10 000 cycles). This facile and effective preparation method of rGO/NPC electrodes possesses great potential in the fabrication of next-generation electrochemical capacitors with excellent capacitance performance.

“…In addition, the electrochemical performance of N-NTC-900 was investigated in 1 M LiClO 4 /acetonitrile organic solution. The corresponding capacitance current is almost three times lower than that in 6 M KOH electrolyte (Figure S14), which may be due to the low conductivity of organic solution and/or the micropore-dominated structure of N-NTC-900 . Therefore, it is suggested to be applied in the aqueous solution for energy storage.…”

A nitrogen-doped nanotubular carbon (N-NTC) aerogel with high porosity was synthesized via a simple in situ template-growth approach using melamine-cyanuric acid (MCA) supramolecular aggregates as the template-forming agent and nitrogen source for high-performance supercapacitors (SCs). MCA/carbon (MCA/C) aerogel was first synthesized through in situ reassembly of MCA to form a rodlike template and polymerization of glucose at the periphery of the MCA template under hydrothermal conditions, and then, the N-NTC aerogel with high N-doping and high porosity was obtained by subsequent pyrolysis of MCA/C and decomposition of MCA. The as-prepared N-NTC aerogel presented a unique one-dimensional structure with a high N content, superhigh specific surface area, large internal diameter, and uniform wall thickness. The formation mechanism of the N-NTC aerogel was analyzed systematically, and the morphology, structure, and chemical properties of the resultant N-NTC aerogel were fully investigated at different carbonization temperatures. As the electrode material of SCs, the N-NTC aerogel obtained at 900 °C carbonization and delivered a superior specific capacitance of 563 F g −1 at 1 A g −1 . The corresponding symmetric SC device exhibited a high energy density of 21 Wh kg −1 at a power density of 1217 W kg −1 . This method is also applicable to the synthesis of many other carbohydrate-based N-NTC aerogels.
