Abstract

This study investigates the effect of SiO₂–TiO₂ nanocomposite coating with polyaniline (PANI) addition on the wettability properties of textile fabrics. The research was conducted through a laboratory-scale experimental approach by applying nanocomposite coatings onto textile substrates using the dip-coating method. Calcination temperatures of 600°C, 700°C, 800°C, and 900°C were employed to evaluate the influence of thermal treatment on surface characteristics. Wettability performance was assessed by measuring water contact angles before and after twenty washing cycles to determine coating durability. The results indicate that all coated fabrics exhibited hydrophilic behavior, characterized by contact angles below 90°, demonstrating enhanced surface affinity toward water. Variations in calcination temperature significantly affected the contact angle values, reflecting changes in surface structure and chemical properties of the nanocomposite layer. After repeated washing, a decrease in hydrophilic performance was observed, suggesting partial degradation or detachment of the coating layer. The presence of PANI, which contains polar functional groups, is considered to contribute to improved surface wettability. Overall, the SiO₂–TiO₂/PANI nanocomposite coating shows potential for functional textile applications requiring controlled hydrophilic properties, although further optimization is necessary to improve long-term stability.

Abstract

This study investigates the effect of SiO2–TiO2/PANI nanocomposite concentration on the surface morphology of cotton fabrics relevant to self-cleaning performance. A controlled laboratory experiment was conducted using four compositional ratios, while TiO2 content was fixed to isolate the structural role of SiO2 and PANI. Nanocomposites were synthesized via a sol–gel route, deposited by dip coating, and characterized using SEM combined with quantitative image analysis. The results demonstrate a systematic morphological evolution from relatively homogeneous, fine particle distributions to coarser and more agglomerated structures as PANI concentration decreased. Particle size distributions ranged predominantly between 40–90 nm, with higher PANI fractions promoting dispersion uniformity and reduced surface roughness. Increasing SiO2 dominance intensified particle growth and agglomeration, indicating altered interfacial interactions within the composite layer. Comparative analysis with prior studies confirms that oxide–polymer balance governs micro–nano architecture on textile substrates. These findings elucidate composition–structure relationships critical for optimizing functional textile coatings

Abstract

This study examines the influence of compaction temperature on Marshall stability in hydrophobic self-healing hybrid asphalt using a quantitative laboratory experimental approach. The asphalt mixture was formulated with penetration grade 60/70 binder and standard aggregates, modified by nanosilica to enhance hydrophobic characteristics and Escherichia coli as a biological self-healing agent. Compaction temperatures of 180°C, 185°C, and 190°C were evaluated alongside a 150°C control sample without modification. The results indicate a non-linear relationship between temperature and mechanical performance, with stability increasing to an optimum condition at 185°C before declining at higher temperatures. This trend reflects improved densification and aggregate interlocking at moderate temperatures, while excessive heat reduces binder effectiveness due to softening. Volumetric parameters further demonstrate that optimal temperature conditions contribute to balanced void distribution and improved binder efficiency. Additionally, the hybrid system exhibits multi-scale interactions between nano-modification and microbial healing mechanisms, enhancing durability and resistance to environmental factors. These findings emphasize the importance of precise thermal control in optimizing both structural integrity and functional performance of advanced asphalt materials.
