“…Self-cleaning and bactericide coatings provide other examples of highly irregular surfaces exploited to obtain specific properties (see, e.g., Refs. [303][304][305][306][307][308][309][310][311][312][313]).…”

In Mechanics, material properties are most often regarded as being given, and based on this, many technical solutions are usually conceived and constructed. However, nowadays manufacturing processes have advanced to the point that metamaterials having selected properties can be designed and fabricated. Three-dimensional printing, electrospinning, self-assembly, and many other advanced manufacturing techniques are raising a number of scientific questions which must be addressed if the potential of these new technologies is to be fully realized. In this work, we report on the status of modeling and analysis of metamaterials exhibiting a rich and varied macroscopic response conferred by complex microstructures and particularly focus on strongly interacting inextensible or nearly inextensible fibers. The principal aim is to furnish a framework in which the mechanics of 3D rapid prototyping of microstructured lattices and fabrics can be clearly understood and exploited. Moreover, several-related open questions will be identified and discussed, and some methodological considerations of general interest are provided.

“…Additionally, when applied to everyday life, superhydrophobic surfaces can be damaged by photo-(solar UV irradiation) or thermal degradation of hydrophobic chemicals. Depending on the field of application, most published works focused their attention on improving mechanical robustness [126,127], antibacterial and anti-biofouling stability [126,128], long-term chemical stability [129][130][131], adhesion strength [132], and resistance to high-speed drop/jet impact of liquid [133]. Indeed, these properties are of primary importance for many applications, such as in surgical instruments, naval construction steel, marine coatings, wind turbine coatings, industrial equipment, fabric coatings, etc.…”

The development of innovative materials is one of the most important focus areas in heritage conservation research. Eligible materials can not only protect the physical and chemical integrity of artworks but also preserve their artistic and aesthetic features. Recently, as one of the hot research topics in materials science, biomimetic superhydrophobic materials have gradually attracted the attention of conservation scientists due to their unique properties. In fact, ultra-repellent materials are particularly suitable for hydrophobization treatments on outdoor artworks. Owing to their excellent hydrophobicity, superhydrophobic materials can effectively prevent the absorption and penetration of liquid water as well as the condensation of water vapor, thus greatly relieving water-induced decay phenomena. Moreover, in the presence of liquid water, the superhydrophobic surfaces equipped with a self-cleaning property can clean the dirt and dust deposited spontaneously, thereby restoring the artistic features simultaneously. In the present paper, besides the basic principles of wetting on solid surfaces, materials, and methods reported for preparing bioinspired ultra-repellent materials, the recently proposed materials for art conservation are also introduced and critically reviewed, along with a discussion on the droplet impact and durability of the artificial superhydrophobic surfaces. Lastly, the current status and the problems encountered in practical application are also pointed out, and the focus of future research is presented as well.

“…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
