“…ZnO can be identi ed as n-type semiconductor with a wide band gap (3.37) eV. Owing to the electron transitions from the valence band to the conduction band, ZnO NPs reveals signi cant absorption peak between the range of 350-380 nm wavelength [40]. It is interesting to note that the CZ nanocomposites sample demonstrates a sharp absorption peak appeared at around 378, the change in the characteristics of absorption peak can be corresponded to the interactions of ZnO-NPs and CS polymer chains lead to the absorption peak of CS-ZnO to be increased in the visible light region with high intensity compared to CS-Z and ZnO, NPs which indicates the decrease in band gap [41].…”

This study investigates the creation and analysis of chitosan-zinc oxide (CS-ZnO) nanocomposites, exploring their effectiveness in inhibiting bacteria. Two synthesis approaches, physical and chemical, were utilized. The CS-ZnO nanocomposites demonstrated strong antibacterial properties, especially against Staphylococcus aureus, a Gram-positive bacterium. Chemically synthesized nanocomposites (CZ10 and CZ100) exhibited larger inhibition zones (16.4 mm and 18.7 mm) compared to physically prepared CS-Z5 and CS-Z20 (12.2 mm and 13.8 mm) against Staphylococcus aureus. Moreover, CZ nanocomposites displayed enhanced thermal stability, with decomposition temperatures of 281°C and 290°C, surpassing CS-Z5 and CS-Z20 (260°C and 258°C). The residual mass percentages at 800°C were significantly higher for CZ10 and CZ100 (58% and 61%) than for CS-Z5 and CS-Z20 (36% and 34%). UV-Visible spectroscopy revealed reduced band gaps in the CS-ZnO nanocomposites, indicating improved light absorption. Transmission electron microscopy (TEM) confirmed uniform dispersion of ZnO nanoparticles within the chitosan matrix. In conclusion, this research underscores the impressive antimicrobial potential of CS-ZnO nanocomposites, especially against Gram-positive bacteria, and highlights their enhanced thermal stability. These findings hold promise for diverse applications in industries such as medicine, pharmaceuticals, and materials science, contributing to the development of sustainable materials with robust antimicrobial properties.

“…Material tekstil self-cleaning hidrofobik memiliki keuntungan menjadi tetap bersih karena memiliki sifat dapat menolak air, kotoran, bau [2], mengurangi kelembapan dan dikenal lebih efektif dalam menghilangkan pengotor [1]. Tekstil hidrofobik dapat didefinisikan sebagai tekstil dengan sudut kontak air ≥ 90º [3].…”

“…ZnO juga memiliki kemampuan membentuk spesies oksigen reaktif dengan adanya sumber cahaya yang sesuai dapat diaplikasikan dalam industri tekstil multifungsi. Nanopartikel oksida logam ZnO banyak digunakan sebagai coating agent pada kain untuk menambah fungsi kain seperti UV-blocking [1], antibakteri [7], retardasi api dan self-cleaning [2]. ZnO dapat menjadi kandidat agen self-cleaning pada kain katun karena ZnO memiliki sifat fotokatalitik [8], hidrofobik [9] dan juga hidrofilik [10].…”

Penelitian ini bertujuan untuk membuat material komposit dari kitosan dan ZnO juga pengaplikasiannya sebagai agen hirofobik kain katun melalui proses pelapisan komposit kitosan-ZnO pada kain katun. Pembuatan komposit kitosan-ZnO menggunakan metode sol-gel dengan variasi perbandingan volume kitosan terhadap ZnO yaitu 7:3, 6:4, 5:5, 4:6 dan 3:7. Kain katun terlapisi komposit kitosan-ZnO diukur hidrofobisitasnya menggunakan metode water contact angle (WCA) dan dihasilkan sudut kontak air tertinggi 131º pada variasi kitosan: ZnO sebesar 7:3. Karakterisasi komposit kitosan-ZnO menggunakan instrument FTIR dan XRD. Hasil FTIR menunjukkan adanya interaksi kitosan dengan ZnO, hal ini didukung adanya gugus C=O yang teramati pada bilangan gelombang 1556 cm-1, gugus C-N tampak pada 1397 cm-1 dan 1338 cm-1, gugus –OH dan –NH terdeteksi pada 3242 cm-1, ikatan O-Zn-O teridentifikasi pada 425 cm-1 dan juga ikatan -C-O-C- antara gugus kitosan dengan ZnO terlihat pada 1019 cm-1 dan 1052 cm-1. Hasil XRD menunjukkan puncak pada 2θ 37,1º, 246,82º dan 68,31º enunjukkan adanya fasa kristalin nanopartikel ZnO serta puncak karakteristik kitosan pada 2θ 10,6º dan 21,8º. Hasil karakterisasi FTIR dan XRD menunjukkan bahwa komposit kitosan-ZnO telah berhasil disintesis. Kata kunci : Hidrofobik, Komposit Kitosan-ZnO

“…During their study, some authors successfully prepared binary chitosan–ZnO nanocomposite by using the precipitation method. 11 Cotton fabrics were treated with the respective bio-nano-composite using pad-dry-cure 12 and sol-gel 13 methods to increase their washing resilience at multiple cycles. (3-Glycidyloxypropyl) trimethoxysilane was used to improve the washing sturdiness of the coatings.…”

This minireview presents recent developments in surface nano-structured textiles and their biomedical applications by up-to-date achievements, summarizing the coatings made of biopolymer films and nanoparticles on different textile substrates for enhanced medical applications, diminishing the incidence of the multiple range of hospital-acquired infections in the past 10 years. The combination of metal and metal oxide nanoparticles with biopolymers is an efficient technique to generate enhanced antibacterial, virucidal and antifungal properties to textiles. Only a few review articles offer a comprehensive insight into the surface tailoring of textiles by nanoparticles–biopolymers use as an alternative for surface modification of textiles, granting them biocidal performance. The overview points out the compelling reasons for scientists and experts to enhance the already existing results in the biomedical textiles domain, with an emphasis on antimicrobial responsivity, highlighting: (a) the benefit of the simultaneous nanoparticles–biopolymers deposition on textiles by various deposition techniques, meaning the wash fastness of the antibacterial attributes and the biocompatibility of the material in comparison with only nanoparticle coating; (b) the use of biopolymers to stabilize colloidal dispersions of nanoparticles, granting the nanoparticles functionalities for covalent immobilization on textiles with long-lasting antibacterial effect; (c) the most usual metal and metal oxide nanoparticles and biopolymers for antibacterial textile applications.
