“…The products can meet the requirements of low formaldehyde emission in much application area. 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 ].…”

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.

“…Metal–organic frameworks (MOFs) are a new class of porous coordination polymers ,, with a large surface area, adjustable pore size, and ordered crystal structure. ,, They have been widely employed for the supercapacitor electrode materials. − Besides, MOFs are also used as precursors or templates to prepare metal oxides/sulfides, − porous carbon, − and composite materials − with excellent electrochemical performance. As we know, the Ni-based MOFs, which are composed of metal ions and one kind of organic ligand, have been widely studied as electrode materials for supercapacitors and show excellent electrochemical performance.…”

A Cu 2+ and Zn 2+ bimetallic doped metal−organic framework Ni 2 (bdc) 2 (dabco) (CuZnNi−MOF, where bdc is 1,4benzenedicarboxylic acid and dabco is 1,4-diazabicyclo[2.2.2]-octane), has been successfully synthesized by the solvothermal method. The carbon-held metal compound nanoparticles (MCN@C) and metal oxide composite (CuOZnONiO) were subsequently obtained by using the CuZnNi−MOF as the precursor. The electrochemical performance of the prepared samples was evaluated in an electrolyte with and without a redox additive (K 4 Fe(CN) 6 ). The specific capacity of the samples tested in the electrolyte with Fe(CN) 6 4− /Fe(CN) 6 3− has a high value of 112.5 mA h g −1 at 1 A g −1 , which is much higher than that measured in the electrolyte without the redox additive, indicating that the Fe(CN) 6 4− /Fe(CN) 6 3− redox couple can effectively enhance the electrochemical performance of electrode materials. An asymmetric supercapacitor (ASC) CuZnNi−MOF//PEDOT-AC (poly(3,4ethylenedioxythiophene)-activated carbon) was further assembled and tested in 3 M KOH + 0.05 MK 4 Fe(CN) 6 electrolyte. The ASC shows a high energy density of 25.2 W h kg −1 , a maximum power density of 8 808 W kg −1 , and also superb cycling performance. Moreover, two assembled ASCs in series connection are found to be able to light up a red light-emitting diode for at least 20 min.

“…For example, at 50 A g −1 , there is only about 5% decline after 100 000 cycles in the charge-discharge tests. 29 In addition, as compared with the other porous carbon materials obtained from diverse MOFs, [30][31][32][33][34][35][36][37] SPC shows far superior capacitance retention to others in a long cycling test as shown in Fig. 6d.…”
