- ItemA poly(3-hydroxybutyrate)-chitosan polymer conjugate for the synthesis of safer gold nanoparticles and their applications(Royal Society of Chemistry, 2018-01-01) Silvestri Daniele; Waclawek Stanislaw Witold; Sobel Bartłomiej; Torres Mendieta Rafael Omar; Novotný Vít; Nguyen Nhung Anh Huynh; Ševců Alena; Vellora Thekkae Padil Vinod; Müllerová Jana; Stuchlík Martin; Petrangeli Papini Marco; Černík Miroslav; Varma RajendraA facile and eco-friendly approach is developed for the synthesis of a poly(3-hydroxybutyrate)–chitosan (PHB–chit) polymer conjugate, which is an ideal material for the synthesis of safer gold nanoparticles (nAu). The synthesized products are characterized by various electron-based, optical and spectroscopic techniques including the catalytic activity and the stability/toxicity of nAu. In contrast to the conventional synthesis approaches, the use of PHB–chit results in generation of a highly stable and size-controlled nAu material that exhibits important catalytic activity towards the reduction of 4-nitrophenol (4-NP) to 4-aminophenol, and at the same time shows no toxicity against living bacterial systems such as Escherichia coli or Staphylococcus aureus. The synthesis route reported herein would inspire future developments that circumvent toxicity issues of relevance to living systems while performing common catalytic experimentation.

- ItemEffective poly(ethylene glycol) methyl ether grafting technique onto Nylon 6 surface to achieve resistance against pathogenic bacteria Staphylococcus aureus and Pseudomonas aeruginosa.(Kluwer Academic Publishers, 2018-01-01) Swar Sumita; Máková Veronika; Müllerová Jana; Horáková Jana; Dolenský Bohumil; Řezanka Michal; Stibor Ivan; Šubrtová PetraOur study is focused on an efficient reduction of amide functional groups to secondary amine on Nylon 6 surface with borane–tetrahydrofuran (BH3–THF) complex, followed by N-alkylation with benzyl chloride (C6H5CH2Cl) which has been successfully used as a model system for further grafting of the reduced Nylon 6 surface by poly(ethylene glycol) methyl ether tosylate (Me-PEG-OTs). The amine-activated surface has been obtained by treatment of reduced Nylon 6 with n-butyllithium or tert-butyllithium in THF. Modified Nylon 6 has been found to be antibacterial particularly due to the presence of hydrophilic poly(ethylene glycol) methyl ether (H3C-PEG) chains. The surface modifications were successfully characterized by various techniques. Water contact angle and free surface energy analyses indicated a significant change in the surface morphology. It was further supported by scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy and Raman spectroscopy. Finally, antibacterial tests were performed against two pathogenic bacterial strains Pseudomonas aeruginosa (CCM 3955) and Staphylococcus aureus (CCM 3953).

- ItemLaser surface modification of electrically conductive fabrics: Material performance improvement and design effects(ELSEVIER SCI LTD, 2018-01-01) Tunáková Veronika; Hrubošová Zuzana; Tunák Maroš; Kašparová Marie; Müllerová JanaDevelopment of lightweight flexible materials for electromagnetic interference shielding has obtained increased attention in recent years particularly for clothing, textiles in-house use and technical applications especially in areas of aircraft, aerospace, automobiles and flexible electronics such as portable electronics and wearable devices. There are many references in the literature concerning development and investigation of electromagnetic shielding lightweight flexible materials especially textile based with different electrically conductive additives. However, only little attention is paid to designing and enhancing the properties of these special fabrics by textile finishing processes. Laser technology applied as a physical treatment method is becoming very popular and can be used in different applications to make improvement and even overcome drawbacks of some of the traditional processes. The main purpose of this study is firstly to analyze the possibilities of transferring design onto the surface of electrically conductive fabrics by laser beam and secondly to study of effect of surface modification degree on performance of conductive fabric including electromagnetic shielding ability and mechanical properties. Woven fabric made of yarns containing 10% of extremely thin stainless steel fiber was used as a conductive substrate.
- ItemMaterial, structure, chosen mechanical and comfort properties of kinesiology tape(Taylor and Francis Ltd., 2017-01-01) Tunáková Veronika; Tunák Maroš; Müllerová Jana; Kolínová Marcela; Bittner VáclavThe main objective of this paper is to determine material composition, structure, and chosen mechanical and thermo-physiological comfort properties of selected kinesiology tape. The results of experiments show that kinesiology tape is a non-linear elastic and porous composite material. Warp yarns are corespun elastic yarns, while weft yarns are 100% cotton yarns. Fabric has a plain weave and its back side is equipped with an adhesive. Tensile strength of kinesiology tape ranges from 80 to 180 N depending on the tape width. In a relaxed state, porosity together with air permeability and other heat and mass transfer characteristics are mainly affected by the compact layer of adhesive on the surface of woven fabric. During tensioning, pores are expanding and therefore transfer of air and water vapor is significantly increased and at the same time heat transfer is reduced which can positively affect wearer comfort.
