This work reports our recent efforts on the preparation of functionalized multi‐walled carbon nanotubes (f‐CNTs) and its application in improving the fire, conductive, and mechanical performance of epoxy resin (EP) composites in combination with graphite sheets (GSs). The addition of hybrid carbon nanomaterials can effectively improve the mechanical properties of epoxy. Consequently, when the mass fraction of f‐CNTs/GSs is 3.9 wt%, the limiting oxygen index (LOI) value is increased to 27.4%, and the tensile strength and notched impact strength of epoxy are increased by 33.5% and 44.8%, respectively. Increasing the content of carbon nanomaterials can further improve the flame retardancy and electrical conductivity of EP composites. For the sample containing 11.0 wt% f‐CNTs/GSs, the electrical conductivity is further increased to 1.7 × 10−3 S/cm, which can be regarded as conductive materials. The LOI value is reached to 28.6%, with peak heat release and total heat release reduced by 26.4% and 16.4%, respectively.

“…With a loading of 0.2% of MWCNTs, the water contact angle at 0 s was 88.7 • , and the lack of increase in hydrophobicity could be due to the low loading of MWCNTs in the polymer matrix. A similar study with MWCNTs incorporated in acrylic resin showed that contact angles only showed a significant increase at 6 wt% [78]. Due to the high viscosity of polyurea, the addition of a higher loading of MWCNTs resulted in the solution being difficult to work on.…”

This study, for the first time, focused on the fabrication of nonporous polyurea thin films (~200 microns) using the electrospinning method as a novel approach for coating applications. Multi-walled carbon nanotubes (MWCNTs) and hydrophilic-fumed nanosilica (HFNS) were added separately into electrospun polyurea films as nano-reinforcing fillers for the enhancement of properties. Neat polyurea films demonstrated a tensile strength of 14 MPa with an elongation of 360%. At a loading of 0.2% of MWCNTs, the highest tensile strength of 21 MPa and elongation of 402% were obtained, while the water contact angle remained almost unchanged (89°). Surface morphology analysis indicated that the production of polyurea fibers during electrospinning bonded together upon curing, leading to a nonporous film. Neat polyurea exhibited high thermal resistance with a degradation temperature of 380 °C. Upon reinforcement with 0.2% of MWCNTs and 0.4% of HFNS, it increased by ~7 °C. The storage modulus increased by 42 MPa with the addition of 0.2% of MWCNTs, implying a superior viscoelasticity of polyurea nanocomposite films. The results were benchmarked with anti-corrosive polymer coatings from the literature, revealing that the production of nonporous polyurea coatings with robust strength, elasticity, and thermal properties was achieved. Electrospun polyurea coatings are promising candidates as flexible anti-corrosive coatings for heat exchanges and electrical wires.

“…[114] While excellent compatibility of ILs with plenty of nanoparticles makes the ionogel nanocomposites show amazing potentials in the field of materials science. There has been a lot of ionogel nanocomposites developed, nanoparticles including SiO 2 , functionalized SiO 2 , halloysite nanotubes (HNTs), metal oxide (such Fe 3 O 4 ), carbon nanomaterials [115][116][117][118][119][120][121][122] and so on have been applied in ionogels to date. [123][124][125][126][127] It's worth noting that nanometal materials such as silver nanowires (AgNWs) or silver nanoparticles (AgNPs) have been serving as conductive filler in hydrogels for a long time.…”

Ionogels have aroused wide interests in the field of flexible electronics. The combination of solid‐state networks and ionic liquids opens up thousands of possibilities for ionogels. The unique structures of ionogels endow them excellent mechanical properties, conductivity and thermal stability to approach the challenge of flexible electronic. A large number of new ionogels have been developed by different methods including the exchange of solution, polymeric ionic liquid and in‐situ reactions in ionic liquids (gelation of low molecular weight gelators, self‐assembly of block polymers, formation of double‐network structure, ionogel nanocomposites and direct polymerization of polymerizable monomers). The aim of this review is to discuss different preparation methods of ionogels and the comparison of their advantages.
