“…Improvement of adhesion between the nonwoven and the nanofibrous coatings was reported, which was attributed to the increased wettability of the supporting polypropylene fabric and polar functional groups introduced by plasma treatment allowing a stronger interaction between the treated fabric and coatings [33,35].…”

“…Introduction of functional groups at the fiber surface helps to form affinity or chemical bonds with a coating material leading to an adhesion improvement [33,34,35]. For instance, Šimor et al [36] used atmospheric-pressure nitrogen plasma as a pretreatment to render the surface of polyester nonwoven fabric hydrophilic for subsequent electroless nickel plating.…”

Plasma treatment has been used for surface activation and modification of textiles. The ionized, highly reactive species, such as ions, electrons, and radicals, in plasma modify the surface of the substrate material, and the composition of plasma depends on the gas used. Plasma technology is an environmentally friendly process and resource-efficient in nature. There is no solvent emission or wastewater in the process and drying processes with high energy and time consumption are not required. The textile applications of plasma include sterilization, wettability and hydrophobicity, dyeability enhancement, flame-retardant finishing, and antimicrobial properties. Plasma surface modification applied to fiber is a way to add value to a nonwoven fabric and enhance the functional performance of the final product. This chapter provides an overview of the plasma treatments of nonwovens that enhance their surface-related properties.

“…Specific surface area was calculated from Brunauer-Emmet-Teller equation. Phase compositions and contribution of ceramic phase in the modified filter were presented elsewhere (Colmenares et al, 2015). Zeta potentials for raw PP nonwoven and PP-ZnO filter were determined based on streaming potential measurements conducted using electrokinetic analyser Anton Paar SurPASS.…”

Hybrid filter material was obtained via modification of polypropylene (PP) nonwoven with nanosize zinc oxide particles of a high aspect ratio. Modification was conducted as a three-step process, a variant of hydrothermal method used for synthesis of nano-ZnO, adopted for coating three dimensional polymeric nonwoven filters. The process consisted of plasma treatment of nonwoven to increase its wettability, deposition of ZnO nanoparticles and low temperature hydrothermal growth of ZnO rods. The modified nonwovens were investigated by a high resolution scanning electron microscopy (HR-SEM). It has been found that the obtained hybrid filters offer a higher filtration efficiency, in particular for so called most penetrating particle sizes.

“…Hence, nanocomposites may exhibit properties that promise a wider or better performance and the ensued applications as compared to conventional composites. For example, nanocomposites comprising of polymer and nanosize fillers such as metal oxide or carbon has been shown to exhibit unique electrical [2 -4], thermal [5,6] and optical [7,8] properties.…”
