“…Bentz et al [35] stated that both quartz and limestone powders were capable of diminishing the initial setting times and facilitating cement early-age hydration. The quartz particles at the macro scale, i.e., the quartz sand, have been applied for the bond enhancement between CF multifilaments and cement-based matrices [9,36], whereas the use of micro-scaled quartz in this regard is very scarce [37]. Furthermore, quartz exhibited negative zeta potentials in an aqueous solution owing to deprotonation on its surface, thus, indicating electrophoretic mobility [38,39].…”

An electrophoretic deposition (EPD) process of micro-quartz (MQ) powder is applied to carbon fibers (CFs) with the aim to enhance their interfacial bond to cementitious matrices and to investigate its influence on the microstructural and mechanical properties of the CFs itself. The electrophoretic mobility of the MQ particles with negative charge in aqueous media was confirmed by potential sweep experiments and zeta-potential measurements. High amounts of MQ were successfully deposited onto the fiber surface, as proven by scanning electron microscopy. Single-fiber tension tests and thermogravimetric analysis showed that EPD treatment had little impact on the tensile properties and thermal stability of the modified fibers. However, storing the CFs in cement pore solution impaired temperature stability of untreated and modified fibers. X-ray diffraction and Raman spectroscopy reveal specific changes of CF's microstructure upon EPD treatment and immersion in pore solution. Single-fiber pullout tests showed that the pullout resistance of MQ-modified CFs was enhanced, relative to untreated CFs. This augmentation can be explained by an enhanced interlocking mechanisms between CF and matrix due to the deposited quartz particles on the CF surface.

“…Nearly all previous works focus on the interfacial modification of surfaces with respect to cementitious matrices. However, according to Li et al, 64 the existing literature on cementitious matrices can be correlated with other alternative binders such as geopolymers. In 2005, Li et al 65 reported that CNT with carboxyl acid groups can react with calcium silicate hydrate (C-S-H) to form strong covalent bonds.…”

Geopolymer nanocomposites incorporating carbon nanotube (CNT)/graphene-based nanomaterials have become an exciting area of research because of their exceptional interface compatibility, providing improved mechanical, electrical, and thermal properties for next-generation construction materials. Accordingly, geopolymers are superior candidates for the implementation of graphene-based nanocomposites. In this paper, a comprehensive examination through equilibrium density functional theory (DFT) with and without the contribution of van der Waals (vdW) dispersion interaction, along with ReaxFF molecular dynamics (ReaxFF-MD) computational modeling approaches, was carried out to comprehend the interaction mechanisms and adsorption energies between graphene-based nanosheets and primary aqueous species of geopolymer structure. Results showed that the interaction of Si(OH)4 aqueous species with the pristine graphene substrate has the weakest physical binding adsorption. The adsorption energy of silicate species on the pristine graphene substrate increased when involving interactions with sodium or potassium cations. Graphene-based nanomaterial surface functionalization with hydroxyl or carboxyl groups led to the higher adsorption energies of silicate and aluminate species due to the stronger electrostatic interaction. Computations also revealed that Na+, compared to K+, mostly increased the interfacial binding between the geopolymer and CNT/graphene-based nanomaterials. The computed MD results exhibited some qualitative agreement with ab initio calculations (at 0 K), with an overestimation tendency as expected due to the contribution of kinetic energy at 300 K. DFT results refute literature assumptions of a covalent oxo-bridging bond between silicon and carbon atoms, confirming electrostatic interactions (Coulomb interaction), with van der Waals (vdW) dispersion forces also playing a significant role in adsorption energy. Our study provides a systematic quantification of missing binding energy parameters and their implications for upscaling interface effects to the nanocomposite level.

“…Jute fibers have been demonstrated to be one of the most popular choices owing to the lower cost, better mechanical properties, and longer individual fiber length than other natural fibers. , Taking advantage of the lower density arising from cell cavities in jute fibers, lightweight composites can be fabricated when jute fibers are used as reinforcing materials. , Nevertheless, the addition of organic fiber components in the polymeric matrix would aggravate the burden on fire hazard, usually leading to more smoke production and increased heat release . Additionally, the mechanical properties of jute fiber-reinforced composites still need to be improved.…”

In this study, aminated halloysite nanotubes (HNTs-NH2) were anchored on the surface of alkali-treated jute fibers to afford HNTs-NH2@Jute as an organic–inorganic composite fiber. The surface modification was evidenced by characterizations including thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). When used as reinforcement in phenolic resins, the obtained HNTs-NH2@Jute can effectively enhance the mechanical properties, improve the lightweight character, and lower fire hazards. HNTs-NH2@Jute can achieve good dispersibility in a phenolic matrix, in which the tensile strength and impact toughness were increased by 93.9 and 88.3%, respectively. The cone calorimetry tests showed that the obtained composite (HNTs-NH2@Jute@PF) exhibited reduced heat release, lowered smoke production, and suppressed carbon dioxide production. Our study afforded a facile approach to construct different kinds of organic–inorganic composite fibers as desirable reinforcements as well as possessing other potential desirable applications.
