Textiles incorporating phase change material have attracted increasing attention due to their temperature regulating function. Although a great progress has been made in the development of phase change material textiles, it has been found that the loading amount of phase change materials is limited by other final properties. Recently, we have propo...

The demand for stretchable strain sensors is increasing due to their potential applications in emerging fields such as human motion detection, wearable electronics, and electronic skins. This review paper provides an overview of the latest developments and advanced applications of flexible carbonous conductive polymer composite strain sensors. Vari...

Textile-based electromagnetic interference (EMI) shielding materials with good flexibility and high EMI shielding effectiveness (SE) are highly desirable. Still, the poor mechanical properties of textile-based EMI shielding materials limit their application. The carbon filaments (CF) combine superior mechanical properties and conductivity. Therefor...

In this study, we investigated how the chemical structural properties, mechanical properties, and morphology of large‐size graphene platelets (LGPs) doped glass fabric (GF)/epoxy composites are affected by varying loading amounts of LGPs. Scanning electron microscope results revealed that the dispersion and filling effect of LGPs can improve the fl...

Durable and stable superhydrophobic surfaces have attracted a great deal of attention, where simplification of their preparation procedures is being explored. Fluorine-containing superhydrophobic surfaces typically exhibit excellent durability, but their use has been constrained by environmental hazards. The presented study reported the facile and...

The Joule heating behavior of carbon-based materials obtained by the process of carbonization of industrial para-aramid fabric wastes are investigated in the present work. Carbonization involves a process of thermally decomposing organic material, thereby altering its physical and chemical properties to obtain carbon-rich materials that are electri...

The stretchable conductive polymers were fabricated by adding conductive activated carbon fillers to the silicon elastomers and subsequently silver electroplating was performed. To solve the ecological and economical footprint issues the waste of Kevlar fibers were converted into activated carbon particles. The microstructure and porous activated c...

Incorporating phase change materials (PCMs) into textiles is one facial method to realize personal thermal management (PTM). Despite the significant progress of PCM-incorporated textiles, the incorporation of PCMs into textiles remains an outstanding challenge. In this work, we described a sandwich-like multi-layer PCM fabric, which consisted of na...

The presented work reported a facile and low-cost approach for creating multifunctional cotton fabrics with hydrophobic, self-cleaning and UV protection properties. The facile dip-pad-dry-cure coating technique was employed to modify the cotton fabric surfaces with 1–3 wt% concentration of ZnO nanoparticles. The characterizations of surface morphol...

Electromagnetic radiation is emitted by most of the electric and electronic devices and shielding from radiation is important. In this study, the Cu/Ni coated ultrathin nonwoven fabric sample was taken to form two-layer of strips and test for electromagnetic shielding effectiveness. The two layered strips were prepared with 3-, 6-, & 9-mm strip thi...

In this research, orthogonal structure carbon fiber reinforced composite was developed and its properties were compared with those of laminated structure composite. To solve the problem of yarn damage caused by friction during the weaving process, a custom‐built weaving device was build up. Compression and vacuum‐assisted resin infusion molding (VA...

The main aim of this work is to develop TiO2 nanoflowers coated polyester (PET) fabric for antibacterial and UV protection applications. The TiO2 nanoflowers were grown on PET fabric by a two-step method. In first step, the polyester fabric was seeded using sol-gel method and in second step the nanoflowers were grown on the seeded PET fabric by hyd...

The introduction of metal particles (MP) in the phase change materials (PCM) realizes the highly efficient thermal energy storage. However, a suitable carrier is necessary for PCM/MP composites for various applications. In this work, the polyethylene glycol (PEG) was used as PCM, five MPs including copper (Cu), aluminum (Al), silver (Ag), iron (Fe)...

In the present study, the embedding ZnO nano‐whiskers (NWs) on carbon fiber (CF) surface was carried out to study the changes in Ohmic heating and mechanical stability of carbon fabric reinforced green epoxy composite laminates. The ZnO NWs were grown onto the CF surface by hydrothermal method and subsequently the laminate composites with different...

Some structural parameters, such as tortuosity, viscous and thermal characteristic lengths, are difficult to obtain through direct measurements. Existing indirect methods, i.e. acoustical method, make it possible to estimate these parameters. This paper presents an application of acoustical inversion methods for estimating structural parameters of...

Fly ash (FA) is a particulate waste generated from the combustion of coal in thermal power plants. The reuse of fly ash as filler in the epoxy matrix has been studied by many researchers. In this review article, the impact of fly ash morphology and content of fly ash filler on the epoxy matrix‘s mechanical property has been discussed from several a...

Embedding of the functional materials into aerogel powders was realized via the filtration method. In this work, the effect of aerogel on the molecule structure of the embedded polyethylene glycol (PEG) was investigated by dispersing aerogel powders in 20wt% PEG aqueous solution with subsequent filtration method. The encapsulation of the PEG in the...

COVID-19 is a pandemic, as such developing a type of material that can inhibit the spread of the novel coronavirus is vital. In this article, copper as metallization material for textiles is discussed for developing disinfection mouth masks or other protective textiles. Copper has been proved to have significant effect against certain bacteria or v...

The objective of present research was to study the Ohmic heating and mechanical stability of carbon fabric/green epoxy laminated composites after incorporation of 0.5, 1 and 3 wt % unmilled and milled fly ash particles. The Ohmic heating behavior was analyzed by estimating temperature response rapidity, maximum temperature, and electric power effic...
