The following study describes the preparation of pectin aerogels and coated with an external layer chitosan. For chitosan-coated aerogels, a modified coating procedure was employed. Since as well are highly water soluble, function chitosan is to slow down dissolution consequently release active substances. Textural properties, surface morphologies, thermal functional groups prepared were determined. Results indicated that affected textural properties resulting in smaller specific areas 276...
Supercritical fluid technology and supercritical carbon dioxide were used for the preparation of hybrid materials – scaffolds from PCL foams chitosan aerogel beads. In a simple straightforward processing method, advanced biomaterials potential tissue engineering applications fabricated, loaded with indomethacin as model drug. The obtained aerogels, foams, evaluated through various characterization techniques: N2 adsorption-desorption analysis, TGA/DSC, microscope/SEM, FTIR. results revealed...
Wound-dressing materials often include other stimulating wound healing. This research describes the first formulation of biodegradable hybrid aerogels composed polylactic acid and pectin. The prepared material showed a highly porous structure with surface area 166 ± 22.6 m2·g−1. addition may have decreased pure pectin aerogel, but it improved stability in simulated body fluid (SBF). aerogel high swelling degradation ratio after 3 h. prolonged its from 24 h to more than one week, depending on...
Hybrid aerogels based on polysaccharides - silica were prepared and characterized. Tetramethylorthosilicate (TMOS) was used as inorganic precursor various (alginate, pectin, xanthan guar) organic precursors. TMOS added to polysaccharide aqueous solutions, resulting in stable wet gels. There no additional chemicals or cross-linkers the process. Produced gels dried under supercritical conditions with CO2 order preserve their structure. The nitrogen adsorption results compared pure aerogels,...
In this research, ethyl cellulose films were prepared by a simple, easy, controlled one-pot method using either ethanol or lactate as solvents, the being formed at 6 °C. Titanium dioxide nanoparticles incorporated to improve oxygen transmission and water vapour rates of obtained films. This used no plasticizers, flexible materials with good mechanical properties obtained. The resulting solvent-free transparent exhibited unique free-shapable properties. had similar those reported in...
Abstract Developing double porous biodegradable and biocompatible scaffolds that can incorporate release drugs in a controlled manner holds immense potential regenerative medicine. This study presents synthesis method for preparing macro-mesoporous scaffold, where poly(lactic acid) adds to the macroporous region mechanical properties, ethyl cellulose surface area (182 m 2 /g). High enables incorporation of model drug indomethacin with an entrapment efficiency 17.0% its later profile. The...
The mechanisms of formation modified thin-film structures based on Ge-Se(S) systems with different Al, Bi, Pb, Te, In modifiers evaporated in vacuum have been determined.The process their growth and the structure is greatly influenced by vapor composition, energetic state its particles, velocity condensation, temperature lining that evaporator.The 〈Ge 0.4 S 0.6 :Х〉 (Bi,Pb,In), Se :In〉 characterized mechanism condensation which realized according to type: vapor-liquid-solid phase...
The ability to design hybrid materials with a hierarchical architecture on multiple-length-scales that simultaneously integrates different chemistries is an emerging trend in engineering. In this article, we report system featuring Si-aerogel network continuously fills the open-cell macroporous structure of polymer network, creating material architectural hierarchy. main thrust manuscript innovative one-pot synthesis strategy that, for first time, uses hydrosol-in-oil HIPEs (high internal...
