“…This outcome is the production of a close compact system; hence, these laminates' enhanced mechanical characteristics can be described (Deshmukh et al, 2021). The hydroxyl-stretch vibration of the CISE composite was lower than that of the CFIPE, CTIPE, and CFTIPE due to inorganic llers' presence (Wu et al, 2020). Further, it can produce a new hydrogen bond with the polymer as an essential constituent of y ash, TiC, and Innegra fabric may also offer some hydroxyl functional groups to create hydrogen bonds with the polymer.…”

“…The llers enhanced the water-resistance and can almost attain the in uence of waterproo ng TiC and y ash (Sun et al, 2019). The surface energy of the laminates improved with the incorporation of llers;furthermore, the appearance of certain hydrophilic inorganic components in epoxy polymer reduced the surface energy(Wu et al, 2020). In this context, the dense architecture affected by the increment of crosslinking and the capillary action of various diameters of pores also outcome in distinct water contact angles(Deshmukh et al, 2021;Ajdary et al, 2020).…”

The present investigation is concentrated on the results of different fillers over the physical, mechanical, and thermal characteristics of the epoxy polymer. These epoxy hybrid composites were produced using mechanical-stirring assisted wet layup method with coir micro-particles, fly ash, Titanium Carbide (TiC) nanoparticles, and Innegra fabrics contains simultaneous considering mechanical stirring with a stirring rod. The tensile, flexural, and inter-laminar shear characteristics of fabricated epoxy hybrid composites were determined using a universal testing machine. After the reinforcement of fly ash and TiC nanoparticles offers the most remarkable improvement in tensile, flexural, and impact strength, about 2.84, 1.65, and 9.19 times compared with pure epoxy polymer. The differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA) showed the epoxy hybrid composites' enhanced thermal stability. The homogeneity of fillers dispersion in the epoxy polymer was observed from a scanning electron microscope (SEM).

“…In addition, polyvinyl alcohol has been incorporated with eggshell powder using the method of solution blending and casting. The FTIR and SEM results have shown that the eggshell particles are well dispersed in the PVOH matrix due to hydrogen bonding interactions, showing that eggshell powder is an excellent biological filler [ 18 ]. Furthermore, acrylamide hydrogels have been modified with the addition of montmorillonite and kaolinite clay.…”

Investigation of Calcination of Sepia officinalis Cuttlefish Bone for Reinforcement of Polyvinyl Alcohol Added Nano-Size Montmorillonite

This study aims to investigate the effects on calcination of Sepia officinalis cuttlefish bone (cuttlebone) to enhance reinforcement of polyvinyl alcohol (PVOH) added with nano-size montmorillonite (MMT) blends as potential bio-compatible materials. The polyvinyl alcohol-cuttlebone-montmorillonite nanocomposites were prepared using the solution casting method. Calcined cuttlebone particles were added to the PVOH matrix at different amount of 2 and 5 parts per hundred resin (phr) along with MMT ranging from 1 to 3 phr. Results showed that the tensile strength of cuttlebone-added PVOH-MMT composites at fixed 1 phr MMT was observed to be marginally lower when the cuttlebone increased from 2 phr to 5 phr due to the poor distribution of agglomerated particles. Nevertheless, at higher loading level of MMT, it was found that the addition of cuttlebone at 5 phr exhibited a reinforcing effect in PVOH-MMT blends. This is consistent with the scanning electron microscopy observation, where dispersion of a higher amount of cuttlebone in PVOH-MMT blends was observed to be more homogeneous than a lower amount of cuttlebone. Moreover, based on the X-ray diffraction analysis, the addition of cuttlebone significantly enhanced the intercalation effect of MMT particles in the PVOH matrix. Furthermore, the observation from infrared spectroscopy shows the amount of hydroxyl group for all composites reduced gradually with the increasing amount of cuttlebone. The addition of cuttlebone showed a “red shift” effect, indicating the formation of hydrogen bonds induced by cuttlebone. Lastly, lower enthalpy of melting was detected in relation to higher loading level of cuttlebone embedded in PVOH-MMT blends through differential scanning calorimetry. In conclusion, the blending of cuttlebone in PVOH-MMT is favorable to obtain better properties of composites.

“…Yew et al used eggshell waste as a new environmentally friendly bio-filler to prepare intumescent fire-retardant coatings, forming a more stable and dense structure of char layer and enhancing the fire retardancy, water resistibility, and adhesion of the coatings [ 12 ]. Wu et al successfully prepared poly (vinyl alcohol) (PVA)/eggshell powder (ESP) bio-composites by the solution-blending method, which can significantly improve the mechanical property and thermostability of the composites [ 13 ]. Xu et al obtained a bio-filler with eggshells for intumescent fire-retardant coatings that effectively promoted the flame retardancy and smoke-suppression performance of intumescent fire-retardant coatings [ 14 ].…”

Comparative Study of Fire Resistance and Anti-Ageing Properties of Intumescent Fire-Retardant Coatings Reinforced with Conch Shell Bio-Filler

et al. 2021

View full text Add to dashboard Cite

Conch shell bio-filler (CSBF) was prepared by washing, ultrasonicating, and pulverizing of conch shells and then was applied in waterborne intumescent fire-retardant coatings. The influence of CSBF on fire resistance and anti-ageing properties of intumescent fire-retardant coatings were studied by using different analytical methods. The fire protection and smoke density tests showed that when the mass fraction of CSBF was 3%, the resulting FRC3 coating had the optimum synergistic flame-retardant and smoke-suppression effects concomitant with a flame-spread rating of 10.7, equilibrium backside temperature of 152.4 °C at 900 s, and smoke-density rating value of 10.4%, which were attributed to the establishment of a more dense and stable intumescent char layer against heat and mass transfer. Thermogravimetric analysis indicated that the presence of CSBF increased the thermal stability and char-forming performance of the coatings, and the char residue of FRC3 rose to 34.6% at 800 °C from 28.6% of FRC0 without CSBF. The accelerated ageing test suggested that the incorporation of CSBF reduced the migration and decomposition of the flame retardants and the yellowing, blistering, and powdering phenomenon, thus improving the structural stability of the coating, resulting in better durability of flame retardancy and smoke-suppression performance.
