The Individual

Nanowire-mesoporous network structured fluorocarbon polymer films were prepared by radio-frequency (RF) magnetron sputtering of a polytetrafluoroethylene (PTFE) target on a poly(ethylene terephthalate) (PET) substrate. The fluorocarbon films were used as precursor materials to prepare fluorocarbon/ZnO double-layered hybrid films by reaction sputtering of a Zn target on the fluorocarbon films. The hybrid films had strong UV absorption that was far larger than the sum of the individual absorptions of fluorocarbon film and ZnO film because of a synergistic effect. The hybrid films exhibited multi-enhanced ultraviolet absorption due to the π-conjugated molecular structure, the nanoparticle-mesoporous reflection of fluorocarbon polymer films, and the absorption effect of nanosized ZnO particles.

In this paper, the possibility to design flexible humidity sensors by spin-coating ofmoisture-sensitive polymer on three types of substrates—poly(ethylene terephthalate) (PET),polylactide (PLA) and composite polysiloxane is investigated. The optical properties, surfacemorphology and roughness of the substrates covered with polymer are studied by transmittancemeasurements and surface profiling, respectively. Thin polymer films of amphiphilic copolymerobtained by partial acetalization of poly(vinyl alcohol) are used as humidity sensitive media. Thesensing properties are probed through transmittance measurements at different levels of relativehumidity (RH). The influence of substrate type is studied by comparing the hysteresis of flexiblesensors with those that are deposited on glass substrates.

In this study, copper films were deposited by magnetron sputtering on poly(ethylene terephthalate) knitted textile to fabricate multi-functional, antimicrobial composite material. The modified knitted textile composites were subjected to microbial activity tests against colonies of Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria and antifungal tests against Chaetomium globosum fungal molds species. The prepared samples were characterized by UV/VIS transmittance, scanning electron microscopy (SEM), tensile and filtration parameters and the ability to block UV radiation. The performed works proved the possibility of manufacturing a new generation of antimicrobial textile composites with barrier properties against UV radiation, produced by a simple, zero-waste method. The specific advantages of using new poly(ethylene terephthalate)-copper composites are in biomedical applications areas.

Fluorocarbon Films

Radio frequency (rf) magnetron sputtering of polytetrafluoroethylene (PTFE) using argon as the working gas was used to prepare hydrophobic fluorocarbon films on a polypropylene substrate. The morphology, structure and hydrophobicity of the fluorocarbon films were analyzed by means of SEM, AFM, XPS and contact angle determination. The growth pattern in this system was a typical one-dimensional (1-D) Volmer-Weber growth mode. The films demonstrated dependence of structure and hydrophobicity on the conditions of preparation. The contact angle decreased with increasing discharge power and increased with increasing pressure. Those trends are attributed to the presence of differing proportions of -CF3, -CF2-, -CF-, and -C- in fluorocarbon thin films prepared with different energy.

Surface Morphologies

Silicon oxide (SiOx) were deposited on many substrates such as silicon, glass, and poly (ethylene terephthalate) (PET) and widely used in industry due to their excellent impressive barrier, electrical, optical and eco-friendly properties. However, few publications that focus on paper as substrate in sputtering have been found. SiOx films were deposited on papers by radio frequency (RF) magnetron sputtering. The influences of process parameters, RF power density and deposition time on deposition rate, surface roughness, mechanical properties and humidity barrier of the films were investigated. The result from atomic force microscopy (AFM) applied to investigate the surface morphologies showed that papers being deposited SiOx (SiOx/Paper) films with the average roughness were much more homogenous and smoother than raw papers. Horizontal, vertical elastic modulus and yield strength of SiOx/Pap clearly increased. The water vapor transmission rate of SiOx/Paper films, which prepared at RF density of 2.78 W/cm2, argon (Ar) flux of 40 sccm and deposition time of 36 min decreased 15times, and the oxygen transmission rate did 10 times. Additional investigations regarding printability focusing on the color reproduction properties were also carried out.
