This article reports the electrospinning technique for manufacturing of multilayered scaffolds bile duct tissue engineering based on an inner layer polycaprolactone (PCL) and outer either a copolymer D,L-lactide glycolide (PLGA) or L-lactide ε-caprolactone (PLCL). A study degradation properties separate polymers showed that flat PCL samples exhibited highest resistance to hydrolysis in comparison with PLGA PLCL. Irrespective liquid-phase nature, no significant mass loss was found 140 days...
Abstract The review presents modern advances in the synthesis of biodegradable polymers based on lactide various topologies and also analyzes main methods for preparation nanoparticles that show promise creation targeted drug delivery systems.
Development of modern medical technologies would be impossible without the application various materials with special properties. Over last decade there has been a marked increase in interest biodegradable for use medicine and other areas national economy. In medicine, polymers offer great potential controlled drug delivery wound management (e.g., adhesives, sutures surgical meshes), orthopedic devices (screws, pins rods), nonwoven scaffolds tissue engineering. Among family polyesters most...
Linear-hyperbranched co(polylactides) containing hyperbranched polyglycerol (PG) block were synthesized and characterized. An estimate of critical micelle concentration as well aggregative stability droplet sizes in the emulsion stabilized by obtained polymers was made. It shown that an architecture linear-branched defines its surface-active properties characteristics dispersion systems from it. With increase PG content copolymers, emulsions increase. Polylactide microparticles organic...
Abstract This article describes the fabrication of non-woven fibrous materials based on sodium alginate by electrospinning and their modification with RGD peptides. The rheological properties solutions are investigated. A defect-free material an average fiber diameter 180 nm was obtained. Ionic covalent crosslinking carried out.
Synthetic surfactants have a wide application in various areas from medicine to agriculture, with biodegradable holding the greatest promise. Promising compounds for synthesis of such are polyethylene oxide and polymers poly(α-hydroxyacid)s: polylactide (i.e. PLA), polyglycolide PGA), poly-ε-caprolactone (PCL), polyhydroxybutyrate (PHB) their copolymers. Because biodegradation polymeric yields natural metabolites, medical biotechnological applications most attractive. A number studies shows...
Objects . To synthesize monodisperse biodegradable hyperbranched polymers based on D,L-lactide in the presence of Boltorn™ H30 polyester polyol as a macroinitiator. Methods 1H and 13C nuclear magnetic resonance (NMR) spectroscopy was used to study chemical structure (Boltorn™ H30)-PDLA copolymers. The molecular weight distribution studied by gel permeation chromatography (GPC). In order thermal stability polyol, thermogravimetric analysis (TGA) used. Polymerization carried out block polyol....
The possibility of synthesizing silatrane-containing polymers was investigated using three different synthetic methods: the formation silatrane fragments from with trialkoxysilyl groups, copolymerization monomers, and reaction silatranes functional copolymers. obtained polymethacrylate copolymers were characterized gel permeation chromatography, IR NMR spectroscopy. It shown that depending on synthesis scheme used, in form three-dimensional structures or soluble products. established...
Objectives. Biologically active polymeric surfactants are a new promising class of macromolecules that can find application in medicine, cosmetology, and agriculture. In this study, number biologically amphiphilic polymers based on branched silatrane-containing polyesters polyethers were obtained, their surface-active properties investigated. Methods. The represented by polyesters, obtained respectively via the anionic polymerization 1,2-epoxypropanol or combination equilibrium...
The colloid-chemical properties of organosilicon surfactants with different solubility in water were studied. behavior various structures model systems - Langmuir films at the water-air interface has been results obtained showed that high stability polymer suspensions is observed only presence insoluble surfactants.
The paper shows the similarity of kinetic regularities vinyl monomers polymerization in presence Laprol 6003, regardless degree solubility water. It is assumed that this feature due to same mechanism formation polymer-monomer particles (PMP) – from monomer microdroplets. interfacial adsorption layer PMPs, main site polymerization, formed a surfactant adsorbed bulk phase and polymer upon initiation polymerization. complex structures particles, incompatibility resulting polymer, high viscosity...
