“…Laser processing has also been employed for producing surfaces exhibiting dual-scale roughness, aiming at applications from microfluidics to self-cleaning devices [67][68][69][70]. For instance, Furstner et al [67] investigated the wetting and self-cleaning properties of three types of superhydrophobic surfaces.…”

“…The wettability of polyorganosiloxane films changed from hydrophobic to superhydrophobic, presenting water contact angles from 144.5 ± 0.7 • to 156.7 ± 1.1 • , while the hysteresis angle decreased from 6.5 ± 0.6 • to 2.5 ± 0.6 • . Wang et al [68] applied superhydrophobic sol-gel on canvas to promote self-cleaning ability. A solar cell device with nanoscale morphology was demonstrated by Zhu et al [69], which presented higher power efficiency than a flat film device and enabled self-cleaning due its topological features.…”

Abstract:The current demand for fabricating optical and photonic devices displaying high performance, using low-cost and time-saving methods, prompts femtosecond (fs)-laser processing as a promising methodology. High and low repetition femtosecond lasers enable surface and/or bulk modification of distinct materials, which can be used for applications ranging from optical waveguides to superhydrophobic surfaces. Herein, some fundamental aspects of fs-laser processing of materials, as well as the basics of their most common experimental apparatuses, are introduced. A survey of results on polymer fs-laser processing, resulting in 3D waveguides, electroluminescent structures and active hybrid-microstructures for luminescence or biological microenvironments is presented. Similarly, results of fs-laser processing on glasses, gold and silicon to produce waveguides containing metallic nanoparticles, analytical chemical sensors and surface with modified features, respectively, are also described. The complexity of fs-laser micromachining involves precise control of material properties, pushing ultrafast laser processing as an advanced technique for micro/nano devices.

“…V zadnjih letih je bilo veliko raziskav na področju doseganja superhidrofobnih lastnosti površine tekstilij [1][2][3][4]. Superhidrofobne površine so zbudile veliko znanstveno in industrijsko zanimanje zaradi svoje vodoodbojnosti in zmanjšanja trenja na površini substrata, lahko pa so tudi samočistilne [1].…”

IzvlečekV raziskavi je bil proučevan vpliv barvanja s tremi reaktivnimi barvili Avitera SE (rumeno, rdeče in modro) na funkcionalne lastnosti bombažnih tkanin, apretiranih z nanodelci SiO 2 , vodo-in oljeodbojno apreturo (FAS) ter kombinacijo obeh (SiO 2 + FAS). Hkrati je bil proučevan tudi vpliv nanesenih apretur na spremembo barve barvanih vzorcev. Prisotnost različnih apretur smo proučevali z vrstično elektronsko mikroskopijo (SEM) in infrardečo spektroskopijo s Fourierjevo transformacijo (FTIR). Vodo-in oljeodbojnost nebarvanih in barvanih apretiranih vzorcev pred pranjem in po njem smo določili z meritvami statičnih stičnih kotov vode in n-heksadekana, kotov zdrsa vode in z ocenami oljeodbojnosti (AATCC 118-1966 T). Barvne lastnosti vzorcev so bile proučevane pred nanosom apretur in po njem, po pranju in dvainsedemdeseturnem osvetljevanju. Prisotnost apreture je bila potrjena tako z rezultati FTIR kot SEM-analize. Superhidrofobne lastnosti so bile dosežene na vseh apretiranih vzorcih in se zaradi predhodnega barvanja niso poslabšale. Kljub nanosu nanodelcev SiO 2 vzorci niso izkazali samočistilnih lastnosti. Nanos vseh apretur je zagotovil oljeodbojnost vzorcev, ki se je na predhodno barvanih vzorcih celo rahlo povečala. Apreture so bile dobro pralno obstojne. Prisotnost apretur je močno vplivala na barvo vzorcev, ne glede na to, ali so bili barvani ali ne. Apretura FAS je povzročila potemnitev in porumenitev vzorcev, medtem ko je apretura SiO 2 vplivala na spremembo barve na modro, rumeno oziroma rdečo. Iz rezultatov barvnih sprememb smo opazili, da so imeli apretirani barvani vzorci zelo slabo barvno obstojnost na osvetljevanje.

At the same time, the influence of applied finishes on the colour change of dyed cotton fabrics was studied as well. The presence of different finishes on cotton was studied using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR

Cellulose possesses excellent properties, but its performance characteristics do not satisfy human requirements completely, which has soured a constant effort to improve its features. Currently, cellulose is combined with inorganics in a process called mineralization that results in a novel type of materials referred to as bio-nanocomposites. There are many examples of mineralized tissues with superior properties in living nature. This circumstance gives us a reason to biomimic them by compounding biopolymers with inorganics. Here, the main mineralization techniques, properties, structure, functionality, and application of mineralized cellulose are the focus. Cellulose can be combined with inorganics through the vapor phase or by the methods of wet chemistry. Much attention has been paid to sol-gel chemistry, which is of first importance in cellulose mineralization. Inorganics can protect polysaccharides, regulate hydrophilicity-hydrophobicity, and impart self-cleaning, antimicrobial and conducting properties, which not only improves them but results in bio-nanocomposites with novel functionalities and performance, not known before for cellulosic materials. Further calcination and carbonization of mineralized cellulose under mild conditions give nanosized metals, metal oxides, and their nanocomposites with carbon, which are often unavailable by conventional methods. Therefore, mineralization is used to develop innovative textiles, oil absorbent and oil/water separating membranes, catalysts and photocatalysts, solar cells, conductors, supercapacitors, transistors and batteries for flexible electronics, and energy storage devices. These nontraditional and highly promising areas for applications have caused an intense interest in cellulose that resembles its rediscovery.
