Engineered Hybrid Nanoclay-Infused Nano-Polymers for Multifunctional Anti-Corrosive Coatings
Abstract: Polymer nanocomposites reinforced with layered nanofillers have emerged as an effective route to enhance structural stability in protective coating applications. Polymer–clay nanocomposites also provide a promising route to enhance mechanical robustness and environmental durability in coating systems. In this study, a hybrid epoxy–polyurethane (EPU) coating was reinforced using organo-modified montmorillonite (o-MMT) and layered double hydroxide intercalated with 2-mercaptobenzothiazole (LDH–MBT). Uniform dispersion and interfacial anchoring between the nanoclays and polymer chains …

New Generation Waste Material as Sustainable Ingredient in Concrete: An Experimental Approach
Abstract: E-waste, including devices like phones and computers, poses serious environmental risks. To mitigate these, the construction industry is exploring e-waste as a material to enhance concrete strength and durability. Hence, the present study assesses the performance of M40-grade high-strength concrete by replacing coarse aggregates with 0% to 30% e-waste plastics at various intervals. As the e-waste replacement increased, fresh concrete's workability decreased gradually. The mix containing 30% e-waste experienced the …

Plant-Derived Fiber-Reinforced Polymer Composites: The Impact of Compatibilizer on the Fundamental Characteristics and Degradation Properties
Abstract: By using compression molding, unidirectional polypropylene (PP) composites reinforced with banana fiber were created both with and without the use of stearic acid (SA) as a coupling agent. Four filler loading levels (10%, 20%, 30%, and 40% by weight) were employed during the composite manufacturing process, using raw banana fiber. The resulting composites underwent mechanical testing (tensile, bending, and impact characteristics). The ideal combination of mechanical properties was found in …

Solar-Responsive Photo-Thermal Polymer Composites with Carbon Nanostructures for On-Demand Water Purification
Abstract: The development of solar-responsive polymer nanocomposites offers a sustainable pathway for water purification. In this work, polyvinyl alcohol (PVA) films reinforced with graphene nanoplatelets (GNPs) and multi-walled carbon nanotubes (MWCNTs) were fabricated and systematically investigated for their mechanical, thermal, viscoelastic, and thermal transport properties. Neat PVA displayed moderate tensile strength (~38 MPa) and high elongation (~165%), whereas 1.0 wt% nanofiller loading enhanced tensile strength to ~52 MPa and modulus to …
