β-Chitinous scaffolds isolated from the skeleton of marine cephalopod Sepia officinalis were used as a template for in vitro formation ZnO under conditions (70 °C) which are extreme biological materials. Novel β-chitin/ZnO film-like composites prepared first time by hydrothermal synthesis, and thoroughly characterized using numerous analytical methods including Raman spectroscopy, HR-TEM XRD. We demonstrate growth hexagonal nanocrystals on β-chitin substrate. Our chitin/ZnO presented this...
Hydrophobic powders were obtained via surface modification of silica or magnesium silicate with selected silanes. A modified precipitation method, carried out in an emulsion system, was used for monodisperse synthesis, while precipitated a traditional water system. Functionalization the inorganic supports performed alkylsilanes: one newly synthesized, 3‐(2,2,3,3,4,4,5,5‐octafluoropentyloxy)propyltriethoxysilane (OPF), and two commercial, octadecylsilane (ODS) octyltriethoxysilane C 14 H 32 O...
The results of studies involving the innovative TiO 2 ‐SiO /Ph‐POSS hybrid were presented. An inorganic oxide composite was precipitated from an emulsion media. functionalisation surface for obtained carried out with use TriSilanolPhenyl POSS (Ph‐POSS) and a silane coupling agent—phenyltrimethoxysilane (PTMS). Electrokinetic physicochemical as well structural characteristics hybrids evaluated. zeta potential value has been determined, which provides relevant information regarding...
Abstract New organic/inorganic hybrid fillers were obtained by mechanical modification of magnesium silicate with selected polyhedral oligomeric silsesquioxane and characterized afterwards. MgO ∙ SiO 2 was precipitated in a water system. The effect chemical surface on their physicochemical properties determined. Functionalization carried out the use different amount (1-(3-hydroxypropyl)dimethylsiloxy- 3,5,7,9,11,13,15-hepta(isobutyl)pentacyclo-[9.5.1.13, 9.15, 15.17, 13]octasiloxane)....
The aim of this work was to specify thermal properties polyolefin composites with copper silicate. Low density polyethylene (LDPE) and polypropylene (PP) 2, 4 8 wt % the filler (CuO·SiO2) were analyzed. Characteristic temperatures polymer compositions, i.e. melting (Tm) crystallization (Tc), obtained by means Differential Scanning Calorimetry (DSC), determined. impact applied additives on stability established using thermogravimetry measurements (TGA). Afterwards, flammability test...
The paper presents preliminary application studies of the innovative TiO2-SiO2/ POSS filler as a potential low-density polyethylene modifier. It was found that addition increases stiffness and hardness composite slightly changes intensity its color.
