“…The morphology was examined using field-emission scanning electron microscopy (SEM) (S-4800, Hitachi, Japan) in which the fracture surfaces were coated with thin gold layer. Differential scanning calorimetry (DSC, PerkinElmer, USA) was used to examine the curing reaction of the uncured EP system at various heating rates (5,10,15, and 20°C/min) in a nitrogen environment. Approximately 6.5 g of the epoxy sample was sealed in an aluminum cup before heating from 25°C to 180°C.…”

The combined effects of phosphorous-jointed epoxidized soybean oil and rice husk–based silica on the flammability and mechanical properties of epoxy resin were examined in detail. The chemical structures of the epoxidized soybean oil, phosphorous-jointed epoxidized soybean oil, and rice husk–based silica were confirmed using Fourier transform infrared spectroscopy and proton nuclear magnetic resonance. Many characteristics of the obtained composite materials were examined, such as the tensile properties, impact strength, flexural strength, critical stress intensity factor (KIC), dynamic mechanical analysis, and flammability. The incorporation of both 10 phr phosphorous-jointed epoxidized soybean oil and 20 phr rice husk–based silica into the epoxy resin yielded the optimum values of the flexural strength, tensile strength, impact strength, and KIC, with increases of 87.78%, 67.23%, 109.34%, and 111.32%, respectively, compared with pristine samples. The limiting oxygen index increased from 23.1% to 29.3%, the peak heat-release rate decreased by up to 37.2%, and the sample satisfied the UL94 V-0 rating.

“…The improvement of the fracture toughness of EPs has attracted the attention of many researchers. [13][14][15][16][17][18][19][20] In addition, the high flammability of EP is the main drawback limiting its application in high-performance areas. 21,22 For this reason, improvement of the flame retardancy of EP is needed.…”

“…Epoxy resins have excellent mechanical properties and electrical insulation properties and other advantages, which possess a wide range of applications. [1][2][3][4][5][6][7] Due to the rising cost and high depletion rates of petrochemical stocks, there is a clear need to reduce the use of fossil fuel-derived monomers in polymer production. This requires research and utilization of natural and renewable resources as monomer alternatives in the polymer industry.…”

The biomass-based chemicals from renewable resources are countermeasures to ease the problem of fossil fuel shortage. This work is to develop a biobased functional reactive modifier for thermosetting epoxy resins appropriate for excellent overall performance. The novel maleimide-cardanol modifiers (CA-HPM) is synthesized from natural extract cardanol (CA) and N-(4-hydroxyphenyl) maleimide (HPM), which is then mixed with phenolic epoxy resin and linear phenolic novolac resin systems. CA-HPM plays a versatile role in tuning the comprehensive properties of epoxy such as thermal property, adhesive property, and thermo-mechanical property. Systems with CA-HPM show slightly lower curing activity and distinct decreased single glass transition temperature (T g ). Besides, the crosslinking density of the cured resin increases, meanwhile the thermal stability keeps at high level, which is due to the rigid five-membered ring structure of maleimide. Metal lap shear test results manifest that the adhesion between epoxy resin and metal interface augments. With 10% CA-1HPM, the cured resin exhibits lower equilibrium water sorption (1.88%) and diffusion coefficient (2.94 Â 10 À8 s À1 cm 2 ). This biobased functional reactive modifier has provided balanced overall performance and would pave the way to a wide range of possible "eco-friendly" applications.

“…Nowadays, nanomaterials attract strong research and application interest. The addition of nanoscale additives to the polymer matrix significantly enhanced the properties of the material [5][6][7][8][9][10][11][12]. Enhancing the properties of coatings with antibacterial function has become a social demand; thus, there is an attempt to mix inorganic nanoparticles (like Ag, ZnO, and TiO 2 ) as antibiotics into paint [13][14][15][16][17][18][19].…”

In this article, ZnO-Ag nanohybrids were chemically synthesized in the aqueous medium by reducing silver nitrate with sodium borohydride NaBH4. These nanohybrids were then homogeneously dispersed into the diacrylate urethane/1,6-hexanediol diacrylate resin system at a content of 2 wt%. The structural morphology, mechanical resistances, and crosslinking of the as-prepared nanocomposite coating (nanocoating) were evaluated. The antimicrobial characteristic was tested by keeping track of the lag-log growth phase of E. coli bacteria in the coating existence among cell cultures. The obtained data indicated that the nanohybrids added into the UV curing diacrylate urethane matrices had significantly increased the abrasion resistance, relative hardness, and conversion of the acrylate groups of the nanocoating. In addition, the antibacterial test revealed that the nanocoating had good antibacterial property against E. coli, whereas for the pure coating (without ZnO-Ag nanoparticles), there was no antibacterial activity observed.
