“…Measuring the surface hardness of any kind of coating polymer materials is of a great importance to determine its performances in various hazardous environments. Therefore, examining the ultimate microhardness properties of these materials are one of the compulsory step so that to judge their possible employments as coating materials . In our ongoing study, the microhardness test was performed to explore the variations of the microhardness properties of the CE/BOZ resin composites upon adding increasing the TBF concentrations and also to confirm the improvements seen in the flexural and IS properties.…”

This present article investigates the effect of silane-treated basalt fibers (TBFs) on the morphological, mechanical and thermal properties of cyanate ester/benzoxazine (CE/BOZ) resin composites. The characterization was made using a scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), flexural test, impact strength (IS) test, microhardness test, dynamic scanning calorimetry, and thermogravimetric analysis. The mechanical test results inferred the distinctive improvements in the values of the flexural strength and modulus, IS, and microhardness of the CE/BOZ composites. The thermal stabilities in terms of the T g , T 5% , T 10% , and T HRI were appreciably improved and were higher than those of the pure CE/BOZ resin. Data from the SEM and FTIR tests ascertained the good dispersion and adhesion between the TBFs and the resin matrix, which might be behind the significant enhancement in the ultimate performances of the composites, with respect to the distinguished properties of BFs.

“…Hence, varying these conditions will result in different values of modulus and T g , and therefore the comparison between different phthalonitrile‐based composites and nanocomposites will be difficult. It is within this view that we choose the same type and amount of curing agent as well as the same curing procedure than previous researches concerned with the preparation and characterization of silicon nitride, alumina, and titania‐based phthalonitrile nanocomposites . The choice of Apph as the curing agent is closely related to the great advantages that can be obtained, such as lowering the curing temperature as well as the participation in the polymerization reaction because the Apph is also a class of phthalonitrile monomers.…”

“…Thus, phthalonitrile resin filled with silicon carbide (SiC) particles exhibited a much more ameliorated mechanical and thermal properties . Silicon nitride (Si 3 N 4 ), alumina (Al 2 O 3 ), and titania (TiO 2 ) nanoparticles also highly improved the thermal and the thermomechanical properties of the typical bisphenol‐A‐based phthalonitrile resin . Moreover, nano‐SiO 2 improved the mechanical, thermal, and dielectric properties of polyarylene ether nitriles terminated with phthalonitrile, and graphene oxide (GO) induced fast curing of amino novolac phthalonitrile …”

In the present work, zinc oxide nanoparticles were treated with aminopropyl trimethoxy silane-coupling agent and used as a new kind of reinforcement for a typical high performance bisphenol-A-based phthalonitrile resin. The resulted nanocomposites were characterized for their mechanical, thermal, and optical properties. Results from the tensile test indicated that the tensile strength and modulus as well as the toughness state of the matrix were all enhanced with the increasing of the nanoparticles amount. Thermogravimetric analysis showed that the starting decomposition temperatures and the residual weight at 800°C were highly improved upon adding the nanofillers. At 6 wt% nanoloading, the glass transition temperature and the storage modulus were considerably enhanced reaching about 359°C and 3.7 GPa, respectively. The optical tests revealed that the neat resin possesses excellent UV-shielding properties, which were further enhanced by adding the nanofillers. Furthermore, the fractured surfaces of the nanocomposites analyzed by scanning electron microscope exhibited homogeneous and rougher surfaces compared with that of the pristine resin. Finally, the good dispersion of the reinforcing phase into the matrix was confirmed by a high resolution transmission electron microscope.

“…The most effective method of further enhancing properties of BPhN polymers is synthesis of nanocomposites. Only recently, the first publications on phthalonitrile nanocomposites appeared in literature [30][31][32][33][34][35][36]. Lei and coworkers [30,31] synthesized the nanocomposites with 5-10 wt% exfoliated graphite nano platelets and improved flexural strength, modulus and thermal stability.…”

The substantial effects of introducing nanoparticles for enchancing thermal and mechanical properties of BPhN-based matrix have been shown.…”

Hybrid nanocomposites based on heterocyclic network, obtained from bisphenol A based phthalonitrile (BAPhN) with different (0.03-5.0 wt%) contents of reactive amino-montmorillonite (MMT) nanolayers, were synthesized and studied for the first time. Their structure, dynamics, thermal, relaxation and elastic properties were characterized using transmission electron microscopy (TEM), mid-infrared (mid-IR), far-infrared (far-IR) and energy dispersive X-ray (EDX) spectroscopies, differential scanning calorimetry (DSC), and by dynamic mechanical analysis (DMA) and thermogravimetry (TGA) measurements performed in both air and nitrogen mediums at temperatures from 20 to 600-900°C. Depending on nanofiller content, different extents of MMT stacks exfoliation, from single nanolayers to MMT stacks with tens nanolayers-thickness, are observed in the nanocomposites. The pronounced dynamic heterogeneity in the glass transition and the 'constrained dynamics' effects are shown. For the pristine matrix, T g (DMA) = 446°С varying from 460 to 570°С for the nanocomposites. After high-temperature treatment in N 2 medium, the relaxation spectrum and glass transition disappear, and constant dynamic modulus E′ ≈ 3 GPa at 20-600°С is registered. A satisfactory thermal stability of the nanocomposites, with retaining the sample integrity is observed at temperatures up to ~500°C in air and up to 900°C in N 2 medium.
