“…The prevailing environmentally friendly and halogen‐free flame retardant was able to improve EP fire retardancy. [ 7–10 ] Recently, inorganic materials, especially one‐dimensional ones, exhibited unique advantages in the field of flame retardant due to form special network structure after burning. [ 11–13 ]…”

Aiming to endow the efficient fire safety to epoxy resin (EP), magnesium hydroxide micro‐whiskers (mw‐MH) as super‐reinforcement were incorporated into EP. The thermal kinetics of EP/mw‐MH micro‐composites were investigated. The limited oxygen index (LOI) of EP with the incorporation of mw‐MH reached up to 33.7% greatly improved comparing to 26.3% of pristine EP. The cone calorimeter test (CCT) showed the heat release rate (HRR), smoke production rate (SPR) of the EP/3mw‐MH with the addition of 3 wt% mw‐MH obviously reduced, as evidenced by the reduction of peak of HRR and SPR for the micro‐composites to 58% and 48%, respectively. Moreover, improvements were also observed in total heat release (THR) and total smoke production (TSP) of EP/3mw‐MH, which were decreased by 29% and 34% at 300 s. Compared with common used industrial magnesium hydroxide (ind‐MH), EP/mw‐MH micro‐composites possessed excellent fire safety performance at the same loading, which was attributed to the jammed network structure. Furthermore, the Young's modulus and tensile strength of EP/mw‐MH micro‐composites maintained. Finally, further investigation was proposed to explain the flame retardant mechanism, which involved the jammed network structures at internal and compact protective char. The magnesium hydroxide with one‐dimensional structure offered an effective method to improve the fire retardancy of polymers.

“…However, they are inherently brittle and possess the low fracture toughness due to the highly cross‐linked structure after curing, restricting their applications as structural and functional materials in many fields 2 . Many efforts have been explored to enhance the mechanical properties of epoxy resins by adding nanofillers (e.g., silica, carbon nanotube, clay, graphene oxide, graphene, layered double hydroxide, boron nitride, and molybdenum disulfide) into epoxy matrix 3–13 . Although the tensile strength of epoxy nanocomposites could be improved because of the high stiffness of these nanofillers, the enhancement in toughness is unsatisfactory.…”

The unique structure and property of K+‐modified graphitic carbon nitride (K‐CN) nanosheets would be beneficial for developing advanced epoxy nanocomposites. However, the compatibility between K‐CN nanosheets and epoxy matrix is a big challenge. In this study, we demonstrate a new and effective method to improve the compatibility of K‐CN nanosheets and epoxy by using 1‐(oxiran‐2‐ylmethyl)‐1H‐indole (IN) as surface modifier through the cation‐π interaction between K+ on the surface of K‐CN nanosheets and indole group of IN. In addition, the covalent bond between epoxy group of IN and amino group of curing agent could be used to participate in the formation of the epoxy network. When the content of K‐CN nanosheets is 0.5 wt%, the tensile strength of prepared epoxy nanocomposites increases by 60.7% and extensibility of prepared epoxy nanocomposites increases by 53.4% compared to neat epoxy resin. In addition, the prepared epoxy nanocomposites are used as efficient reusable photocatalysts for degradation of methylene blue (MB). The efficiency of MB degradation is 98% within 60 min. This work opens up a new avenue to fabricate high‐performance epoxy nanocomposites with multifunctional properties for advanced engineering applications.

“…Silica particles were produced from the rice husk, and they were of very fine dimensions enabling good prospective material for future use in composites [37,38]. The use of the co-precipitated Fe/Al-LDH as the surface modifier on silica obtained from bioresources was a challenge for producing a new composite material having improved properties [39]. The silica particles are a very wellestablished reinforcement used in particle reinforced polymer composites.…”

Silica particles were obtained from rice husk to which layered double hydroxide particles were deposited (weight ratio 1 : 1). Fe 2+ -Al 3+ layered double hydroxides (FeAl-LDH) were synthesized by co-precipitation with ratios Fe : Al of 3 : 1 in the presence of SiO 2 particles from the rice husk. Characterization of the synthesized FeAl-LDH@SiO 2 particles was performed by X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS. Prepared FeAl-LDH@SiO 2 particles were used as reinforcing agents in 1, 3 and 5 wt% quantity in poly (methyl) methacrylate matrix. The aim of this study was to examine whether FeAl-LDH@SiO 2 particles affect the mechanical properties of polymer composite materials. The morphology of the composites was examined using a field emission scanning electron microscope. Microindentation, tensile and impact testing determined the mechanical properties of the obtained composites.
