“…In addition, the robes and coats have an elegant air, which makes the actor's own image more tall and grand and helps to highlight his important position in the family. Therefore, in this drama, robes and coats become one of the main visual elements, often appearing in various occasions, such as rituals and weddings [12]. In addition to ISSN 2618-1568 Vol.…”

With the development of the times and social progress, people begin to focus on the pursuit of spirituality after their material life is satisfied. As a popular art form, film and television dramas are favored by the audience, especially the younger generation. Among them, it has become one of the important ways to spread cultural information because of its audio-visual combination and strong intuitiveness. As a result, more and more directors are focusing on the distinctive characters in film and television dramas. How to express the status, character traits and emotional changes of the characters in the drama through costume modeling has become a key research topic for many scholars. This paper analyzes the positive effects and problems of the interdependence between costume design and film and television performance, in the hope that more scholars and practitioners will explore this field in greater depth.

“…Thus, their functionalization is necessary [32]. Moreover, nano-TiO 2 can improve the physicochemical ( Figure 2) and functional properties of polysaccharide-based materials like starch, sodium alginate, carboxymethyl cellulose, chitosan, pullulan, agar, k-Carrageenan, xanthan gum, and gellan gum-based materials [1,5,17,[20][21][22]33]. .…”

“…The potential biomedical applications of nonconventional polysaccharide-based materials functionalized with TiO 2 have been investigated (Table 5). Razali et al [33] informed that the addition of TiO 2 in gellan gum films improved their thermal stability and antimicrobial activity (by agar test diffusion assay) against S. aureus (inhibition of 10 mm), Streptococcus sp. (inhibition of 12 mm), E. coli (inhibition of 11 mm), and Pseudomonas aeruginosa (inhibition of 10 mm) without significant changes in transparency (transmittance of 94%) compared with the gellan gum-based film (without antimicrobial activity and transmittance of 100%).…”

In recent years, a strong interest has emerged in polysaccharide-hybrid composites and their potential applications, which have interesting functional and technological properties. This review summarizes and discusses the reported advantages and limitations of the functionalization of conventional and nonconventional polysaccharides by adding TiO2 nanoparticles as a reinforcement agent. Their effects on the mechanical, thermal, and UV-barrier properties as well as their water-resistance are discussed. In general, the polysaccharide–TiO2 hybrid materials showed improved physicochemical properties in a TiO2 content-dependent response. It showed antimicrobial activity against bacteria (gram-negative and gram-positive), yeasts, and molds with enhanced UV-protective effects for food and non-food packaging purposes. The reported applications of functionalized polysaccharide–TiO2 composites include photocatalysts (dye removal from aqueous media and water purification), biomedical (wound-healing material, drug delivery systems, biosensor, and tissue engineering), food preservation (fruits and meat), cosmetics (sunscreen and bleaching tooth treatment), textile (cotton fabric self-cleaning), and dye-sensitized solar cells. Furthermore, the polysaccharide–TiO2 showed high biocompatibility without adverse effects on different cell lines, indicating that their use in food, pharmaceutical, and biomedical applications is safe. However, it is necessary to evaluate the structural changes promoted by the storage conditions (time and temperature) on the physicochemical properties of polysaccharide–TiO2 hybrid composites to guarantee their stability during a determined time.

Iodine‐loaded poly(silicic acid) gellan nanocomposite film was fabricated and evaluated for antibacterial properties. Poly(silicic acid) nanoparticles were synthesized by condensation of silicic acid under alkaline conditions in the presence of polyvinyl pyrrolidone, phosphate ions, and molecular iodine. The nanoparticles were incorporated into gellan dispersion to prepare gellan nanocomposite film using the solvent casting method. The nanocomposite films were characterized by Fourier transformed infrared spectroscopy, thermogravimetric analysis, and X‐ray diffraction studies. The results of characterization studies indicated improved thermal stability and an increase in the degree of crystallinity. The scanning electron micrographs and energy dispersive X‐ray spectrum confirmed the uniform dispersion of silica and iodine in the nanocomposite films. The analysis of physical and mechanical properties revealed the enhanced tensile strength, moisture resistance, and higher folding endurance of poly(silicic acid) gellan nanocomposite films as compared to gellan film. Further, the iodine‐loaded poly(silicic acid) gellan nanocomposite films showed good antibacterial activity against Staphylococcus aureus and Escherichia coli and effective mucoadhesive strength. The results indicate that iodine‐loaded poly(silicic acid) gellan nanocomposite mucoadhesive film can be used for potential antibacterial applications in pharmaceuticals.
