“…Telah banyak dilakukan penelitian terkait modifikasi teksil menjadi bahan yang bersifat hidrofobik menggunakan komposit dari polimer organik seperti kitosan dan material anorganik ZnO. Contohnya, penelitian Sulaeman dkk [11] membahas pemanfaatan kitosan/TiO2 sebagai agen self-cleaning pada kain karpet dan agen hidrofobik untuk kain katun [12]. Penelitian lain dari Pradipta dkk [13] menjelaskan pembuatan kitosan-SiO2 dengan metode sol-gel sebagai agen hidrofobik pada kain rayon.…”

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

“…The antibacterial superhydrophobic Ti coatings were important for reducing the occurrence of bacterial infections, reducing device failure and improving patients’ quality of life. Raeisi et al [ 102 ] fabricated antibacterial superhydrophobic chitosan/TiO 2 coatings on cotton fabrics. The antibacterial rate against E. coli and S. aureus bacteria were further increased to 99.8% and 97.3% combining with the superhydrophobicity and the antibacterial properties of coatings.…”

Microorganisms have existed for hundreds of millions of years and they have adapted to colonize on surfaces. [1] Bacteria are ubiquitous in the human living environment. Most bacteria spread through medical equipments and contacting with each other. [2] All over the world, the diseases caused by bacterial infections have brought terrible catastrophe to human beings. [3][4][5][6][7] Generally, people infected with infectious diseases are directly or indirectly related to contact with pathogenic microorganisms. The main stages of the attachment of bacteria at the interface include the migration of bacteria to the surface, the reversible and irreversible interactions between bacteria and the interface, the specific adsorption of bacteria on the substrate, and the proliferation of bacteria, thus forming a bacterial biofilm on the surface (Figure 1). [8] The bacteria can multiply quickly under suitable conditions, which induce various diseases and cause invalidation of apparatus. The colonization of bacteria on surfaces can result in chronic infections, [9] the failure of medical implants, [10] the biological corrosion of industrial equipments, [11] reducing various surface properties, such as petroleum and other pipelines systems, clothes, and other harmful phenomena. [12] Currently, antibiotics are mainly used to inhibit or kill bacteria to maintain surface hygiene and prevent infections. However, as bacteria develop resistance to antibiotics, it is suggested that antibiotics should be much more cautiously used. It is estimated that antimicrobial resistance infections will kill as many as 10 million people every year by 2050. [13] Antimicrobial resistance is now an urgent international issue that requires imperative solutions, more effective antibacterial techniques are needed to fight bacterial infections. Inspired by the superwetting properties of plants and marine life, Li et al. [14] reviewed the research progresses of the preparation of superwetting materials including of superhydrophobic/superoleophilic and superhydrophilic/underwater superoleophobic materials and their applications for removal of organic pollutants, which provided a basis for the design of a new type of superwetting materials that efficiently remove organic pollutants in the water. Similarly, Tian et al. [15] developed a superwetting thin-film nanofibrous composite membrane with antifouling, self-cleaning, and oil-in-water emulsions separation properties. The as-prepared carbon nanotubes (CNTs) layer with superhydrophilic and underwater superoleophobic properties could absorb water as a selective layer to remove oil droplets from oil-in-water emulsions to present antifouling. The self-cleaning properties were promised by the continuously up-flowed permeate water. They claimed that the work provided a new insight for developing oil/water separation membranes which suffer from fouling and clogging. Also, Li et al. [16] summarized the recent progresses in smart polymeric materials for fabricating switchable superwettability surfaces and their oi...

“…titanium dioxide (TiO2) silicon dioxide (SiO2), zinc oxide (ZnO) and silver, have been extensively studied for various textile functionalization. Textile functionalities created by titanium dioxide nano particles (nano TiO2) are mainly in the fields of easy-care and protection finishing, including photocatalytic self-cleaning, antimicrobial activity, ultraviolet (UV) protection and flame retardancy [1,2]. Apart from application on textiles, nano TiO2 has also been researched in use for wastewater treatment.…”

In this work, the influence of nano titanium dioxide (TiO2) finishing on colorimetric properties of polyester fabrics dyed with mono-azo disperse dyes was examined in terms of the degree of shade change, color strength reduction and the percentage of dye lost from the fabrics and color fastness to washing. A self-cleaning effect imparted by nano TiO2 not only removes unwanted stains from polyester fabrics but also the dye molecules situated in the area nearby the fiber surface. Changes in colorimetric properties of the fabrics dyed with Disperse Violet 33, Disperse Red 167.1 and Disperse Blue 79.1 dyes were, therefore, examined. Shade change and reduction in color strength were observed, in addition, the dye quantity within the fiber decreased as a result of nano TiO2 treatment. Higher amount of nano TiO2 brought about a stronger effect on changes in colorimetric values, quantity of lost dye and color fastness to washing of the dyed polyester fabrics. A similar tendency was observed on these 3 mono-azo dyes. A way to achieve optimal functional performance of nano TiO2 finishing with minimal effect on colorimetric properties of the disperse dyes on polyester is by employing low nano TiO2 content and 0.05 % nano TiO2 is recommended in this work. Under such conditions, the color properties of the dyed fabrics were less influenced and in acceptable level, moreover, the resulting color fastness to washing was not affected and comparable to those exposed to reduction clearing process. HIGHLIGHTS Nano TiO2 has been widely known to offer self-cleaning effect to textiles, especially polyester, at the same time, it may also affect the color and fastness properties of disperse dye on polyester Disperse dyes can be destroyed by nano TiO2 present on polyester fibers. This causes a change in shade, color strength, dye loss and fastness to washing of the disperse-dyed polyester An appropriate amount of applied nano TiO2 onto polyester fabric is considered to maintain self-cleaning function performance with minimal effect on colorimetric properties of the disperse dyes on polyester GRAPHICAL ABSTRACT
