“…A variety of new products and processes, including nanomaterials, has been developed to obtain superhydrophobic and oleophobic surfaces. The superhydrophobicity can be obtained by the use of hydrogels, nanocomposites and other nanostructures [15]. Among these additives, zinc oxide nanoparticles (ZnO NPs) are of particular interest, due to their low cost, biocompatibility and biodegradability for environmental applications and to their hexagonal prism shape, which allows an increase in the surface roughness [16,17].…”

In the present work, 100% cotton knitted fabrics were functionalized with ZnO nanoparticles, in order to enhance the hydrophobic properties of the fibers surface. The incorporation methods of ZnO NPs and different types of cotton samples (including polymer coated, and uncoated with and without a nonionic pretreatment) were evaluated, in order to understand the influence in the hydrophobicity values. Cotton fabrics with and without NPs were characterized by ground-state diffuse reflectance, field emission scanning electron microscopy and energy-dispersive spectroscopy, attenuated total reflectance-Fourier transform infrared spectroscopy and water contact angle (WCA). The best results were obtained when the polymer-coated fabric was functionalized using a precursor concentration of 0.2 M, exhibiting superhydrophobic behavior with static WACs of more than 150°. Although pretreated and untreated ZnO-functionalized cotton fabrics had a slightly lower wettability, they showed interesting results, with improvements in WCA from 116° to 143°. In summary, this work demonstrates that the ZnO NPs have a huge potential to be used as surface finishings for the development of easy cleaning fibrous structures.

“…The hemostatic mechanism of genipin/PVA/chitosan based‐buccal patch is described as follows: the protonated amine groups of chitosan interact with platelets and red blood cells (RBC) with negative charge and induce thrombus formation. In addition, the water absorption properties of chitosan improve hemostasis process by concentrating platelets and blood coagulation factors 63,64 . On the other hand, PVA can absorb a large amount of blood from the injured site due to its good water absorption properties.…”

Mucoadhesive buccal patch is a promising dosage form for a successful oral drug delivery, which provides unique advantages for various applications such as treatment of periodontal disease and postdental surgery disorders. The aim of this study is to synthesize a novel multifunctional mucoadhesive buccal patch in a multilayer reservoir design for therapeutic applications. The patches were fabricated through simultaneous electrospinning of chitosan/poly(vinylalcohol) (PVA)/ibuprofen and electrospraying of phenylalanine amino acid nanotubes (PhNTs) containing metronidazole into the electrospun mats through a layer‐by‐layer process. An electrospun poly(caprolactone) (PCL) was used as an impermeable backing layer to protect the mucoadhesive component from tongue movement and drug loss. Buccal patches were characterized using scanning electron microscopy (SEM) and field emission scanning electron microscopy (FESEM) and also evaluated in terms of physicomechanical parameters such as pH, weight, thickness, tensile strength, folding endurance, and mucoadhesive properties. The swelling index of the patches was examined with respect to the PVA/chitosan ratio. The effect of genipin addition to the electrospinning solution was also studied on mucoadhesive and swelling properties. The cell viability of buccal patches was assessed by methylthiazolydiphenyl‐tetrazolium bromide test on L929 fibroblast cell line. The patch with an optimal amount of mucoadhesive polymers (PVA/chitosan 80:20) and crosslinking agent (0.05 g) indicated an ideal hemostatic activity along with antibacterial properties against Streptococcus mutans bacteria. The synthesized multifunctional mucoadhesive patch with a novel composition and design has a great potential for oral therapeutic applications.

“…Generally, chemical finishing involves the addition of different chemicals based on the intended textile end-use [7]. Among the different finishing techniques, chemical finishing has been widely studied due to the current trends together with the customer requirements for high-tech or high-performance applications [9][10][11][12]. In the past two decades, sol-gel-assisted textile finishing has played a vital role in the development of novel applications to improve the basic properties of textiles.…”

The commercial availability of inorganic/organic precursors for sol-gel formulations is very high and increases day by day. In textile applications, the precursor-synthesized sol-gels along with functional chemicals can be deposited onto textile fabrics in one step by rolling, padding, dip-coating, spraying or spin coating. By using this technology, it is possible to provide fabrics with functional/multi-functional characteristics including flame retardant, anti-mosquito, water- repellent, oil-repellent, anti-bacterial, anti-wrinkle, ultraviolet (UV) protection and self-cleaning properties. These surface properties are discussed, describing the history, basic chemistry, factors affecting the sol-gel synthesis, progress in sol-gel technology along with various parameters controlling sol-gel technology. Additionally, this review deals with the recent progress of sol-gel technology in textiles in addressing fabric finishing, water repellent textiles, oil/water separation, flame retardant, UV protection and self-cleaning, self-sterilizing, wrinkle resistance, heat storage, photochromic and thermochromic color changes and the improvement of the durability and wear resistance properties.
