“…At present, a large number of works are devoted to the investigation of bactericidal properties of nanocrystalline titania under uninterrupted UV-radiation exposure [10,50,51]. In our experiments titania modified samples were continuously exposed to UV light for 10 minutes only.It is well known that bactericidal activity of the samples is closely related to its photocatalytic properties and crystalline structure of synthesized titania [52].…”

The titania hydrosol was successfully prepared using the titanium tetraisopropoxide as precursor and the nitric acid as peptizing agent via the low-temperature sol-gel synthesis in aqueous medium and applied to cotton fabric. For cross-linking of titania nanoparticles to cotton the 1,2,3,4-butanetetracarboxylic acid (BTCA) was used as a spacer. The morphology and composition of the surface pure and TiO 2 modified cotton fibers were investigated by the Scanning Electron Microscopy (SEM). The cotton/TiO 2 composite was characterized by the dielectric permittivity.For the estimation of total titania concentration, all samples were calcined at 650°C. The antimicrobial activity of the treated TiO 2 cotton fibers was investigated against Escherichia coli as a model Gram -negative bacteria after exposure to UV-irradiation for 10 minutes.

“…There are many kinds of rubbers, such as butadiene rubber (BR), ethylene-propylene-diene monomer rubber (EPDM), nitrile-butadiene rubber (NBR) [5], styrene-butadiene rubber (SBR), and natural rubber (NR) [5][6][7][8]. Natural rubber shows sufficient tensile strength; tear strength and abrasion resistance for many applications [4,8].…”

“…Natural rubber shows sufficient tensile strength; tear strength and abrasion resistance for many applications [4,8]. On the other hand, NR is an unsaturated polymer, sensitive to oxidation initiated by heat, ultraviolet or gamma radiation [8]. The properties of NR and its products can be enhanced by the addition of different types of antioxidants, such as benzophenone, benzotriazole, and amines [8,9].…”

“…Recently, it has been reported that TiO 2 nanoparticles prepared by ultrasonication, when used as filler in NR, could increase UV protection and antibacterial properties. 17 Both metal oxides represent the most cost effective inorganic reinforcing fillers for the rubber industry over the past decades. Recently, we have reported that the introduction of nanofillers within the NR matrix, with well dispersed particles, is a good choice to enhance the dielectric properties in NR technology 18 .…”

The novelty of the present study relies on the straightforward sonication of ZnO and TiO 2 and incorporation to a complex formulation of latex, with other several organic-inorganic additives that influences the cross-linking reactions. The new elastomer with particles carefully sonicated exhibit improved electrical and mechanical properties. Strong interaction among the nanoparticles and the polymer amorphous phase has been proved by means of FTIR, SEM and XRD analyses. The synergistic effect of hybrid fillers with nanometric dimensions can be used to design high-performance natural rubber nanocomposites with enhanced electrical resistance and good cross-linking degree.
