    Multi-Walled Carbon Nanotubes and Graphene Oxide-Based Epoxy Hybrid Nanocomposites: Investigation of Nanofiller Modification Effect
    (Elsevier, 2025-09-01) Ahmetli, Gulnare; Kocaman, Suheyla; Musayev, Nijat; Ozmeral, Nimet; Isik, Murat
    Multi-walled carbon nanotubes (MWCNTs) are important nanomaterials utilized in various research and technological applications. Graphene oxide (GO) is another fascinating material that can be effectively applied in various fields, including nanocomposite materials, energy storage, biomedical applications, and catalysis. This study first examined the effect of hybridizing a 1:1 wt ratio mixture of modified carboxyl-functionalized MWCNTs (MWCNTCOOH) and graphene oxide (GO) nanofillers on the properties of novel epoxy resin (ER)based composites. GO was synthesized from graphite. The surface modification of both nanoparticles was performed using polyaniline (PANI) and/or ionic liquid 1-butyl-3-methylimidazolium bromide (IL). The hybrid reinforcement ratio in ER ranged from 0.5 % to 2 % by weight. At the reinforcement ratio of 1.5 wt%, the increase in tensile strength of all nanocomposites compared to ER varied between 22.2 % and 62.8 %. Modification with PANI showed improved mechanical, thermal, and electrical conductivity, as well as enhanced durability in hot water compared to IL. Additionally, PANI and IL further increased the chemical resistance of the hybrid nanocomposites. The highest and lowest glass transition temperatures (Tg) correspond to the 1.5 wt% PANIMWCNTCOOH/ GO (108.60 degrees C) and the IL-MWCNTCOOH/ GO (97.99 degrees C) hybrid nanocomposites, respectively. The electrical conductivity ranges in value from 6.9 x 10-8 to 1.22 x 10-4 S/cm, depending on the hybrid nanocomposite type. The nanocomposites demonstrated superior UV resistance compared to ER, showing an absorbance range of 0.305 to 1.391 a.u. Furthermore, the ANOVA test demonstrated the impact of the hybrid filler type and ratio on the nanocomposite's mechanical properties.

    New Biobased Chitosan-Modified Peach Kernel Shell Composites and Examining Their Behavior in Different Environmental Conditions
    (Elsevier B.V., 2024-11-01) Ahmetli G.; Soydal U.; Kocaman S.; Özmeral N.; Musayev N.; Ozmeral, Nimet; Musayev, Nijat; Soydal, Ulku; Ahmetli, Gulnare; Kocaman, Suheyla
    Bisphenol A-type epoxy (ER) is a versatile synthetic polymer preferred for composite materials but non-biodegradability raises challenges for composites recycling in particular. The present study first investigated the potential usability of peach kernel shells (PKSh) waste as fillers in ER to decrease the cost of composite materials and increase their bio-based content. Different chemical modifications were performed to increase the poor compatibility between the hydrophilic lignocellulosic filler and the hydrophobic polymer matrix. The modified PKShs were obtained by alkali treatment (NaOH-PKSh), coating with biopolymer chitosan (CTS-PKSh), and cross-linking of CTS with glutaraldehyde (GA@CTS-PKSh). The aging of composites is a highly topical subject given the increasing use of composites in structural applications in many industries. The composites' thermal stability and dynamic-mechanical properties in different aging environments (water, seawater, and hydrothermal) were examined. The order of the aging conditions in terms of their effects on the composite properties was: hydrothermal > water > seawater. The ER/GA@CTS-PKSh composite was the most resistant to all environmental conditions. The tensile strength of epoxy matrix (ER) increased max. by 7.78 %, 21.11 %, 42.22 %, and 45.46 % in the case of raw, NaOH-PKSh, CTS-PKSh, and GA@CTS-PKSh fillers, respectively. Composites showed higher absorption in both UV and visible regions. © 2024
