“…The peak at 1753 cm − 1 was belonged to –CONH– vibration, which was often called amide I band. A broad absorption around 3170 cm −1 was attributable to stretching modes of primary and secondary amines at the defect sites and their intermolecular hydrogen bonding interactions [ 2 ]. Fig.…”

“…Moreover, the spacers between the g-C 3 N 4 nanosheets, which interact with each other through weak van der Waals forces, also provide nanochannels for water transport while bigger molecules are retained [ 1 ]. Due to this unique nanosheet structure, g-C 3 N 4 exhibited many useful properties with applications in many fields, such as membrane separation materials [ 2 , 3 ], photocatalysis [ 4 – 6 ], and electronic devices [ 7 – 9 ]. Up to now, the main method to prepare g-C 3 N 4 was high-temperature calcination.…”

“…Up to now, the main method to prepare g-C 3 N 4 was high-temperature calcination. However, the specific BET surfaces of these g-C 3 N 4 materials were only 5–35 m 2 /g [ 2 , 4 , 10 ], which seriously limits the displaying of their unique properties in applications [ 4 ]. Then, the enhancement of specific BET surface for g-C 3 N 4 was very important.…”
TMC-incorporated carbon nitride (CN) with hexagonal and quadrangle honeycomb-like structure and having periodic lattice defects linked by –CONH– bond was synthesized through combining the high calcination with the chemical condensation of melamine and 1,3,5-benzenetricarbonyl trichloride. The obtained CN has a tri-s-triazine ring and benzene ring skeleton, which makes it have excellent mechanical and thermal stability. The BET specific surface area was enhanced to about 125.6 m2/g, and the mean pore size is about 3.43 nm. This CN exhibited an excellent adsorption-enhanced photocatalytic performance.Graphical abstract

“…To solve the problem, various modication techniques such as blending, graing, and crosslinking are employed. Among them, doping inorganic nanomaterials have become an important research direction, polymer nanocomposites membranes were prepared by PVA with nano-SiO 2 , 17,18 NaA zeolite, 19 nano-TiO 2 , 20 carbon nitride, 21,22 Ag, 23,24 and other inorganic nanomaterials. Arif et al 17 synthesized PVA/silica membranes by sol-gel derived route for application in pervaporation of isopropanol-water mixture.…”
“…There was a noticeable improvement in the mechanical properties of 2 wt % g‐C 3 N 4 filled PI composites in comparison to pure PI composite. Wang et al . reported the preparation and properties of poly(vinyl alcohol) (PVA)/g‐C 3 N 4 nanocomposite hybrid membranes.…”
A new type of elastomeric composite containing natural rubber (NR) and graphitic carbon nitride (g-C 3 N 4 ) has been successfully prepared with the reinforced property. The reinforcing effect of g-C 3 N 4 in NR composites was examined by cure, mechanical, morphological, and swelling studies. Besides, epoxidized NR with 50-mol % epoxy level (ENR-50) was used as a compatibilizer to enhance the hydrophilic g-C 3 N 4 filler capacity for hydrophobic NR composites. At the same filler load level, the mechanical properties of NR/g-C 3 N 4 composites, such as tensile strength and tensile modulus, were consistently increased with increased ENR-50 content. To note, the ENR compatibilized composites have shown better-reinforced performance, which has been attributed to the hydrogen bonding interactions between the uncondensed amine groups in g-C 3 N 4 and the polar groups in ENR. We believe that these newly prepared NR composites based on g-C 3 N 4 as nonblack filler and ENR-50 as compatibilizer can find potential applications in modern day rubber research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
