UV Curable Self-Healing Structural Epoxy Composite Materials Interfacial Polycondensation Microencapsulation of Healing Agent and Photo-Initiator

The ability of polymeric coatings to self-heal itself from mechanical damage is explored in this paper. Polymeric coatings with self-healing property is one of the important aspects in modern science. It can be used in industries such as oil industry (protection against corrosion), mechanical engineering, aircraft, etc. The polyurethane (PU) microparticles were synthesized on the basis of polypropyleneglycol (PPG) and toluene diisocyanate (TDI) with a method of interfacial polycondensation at the interface water-benzene. Further to study the surface morphology of the microcapsules with healing agent (trimethylolpropanetriacrylate– TMPTA) obtained PU was applied the method of scanning electron and atomic force microscopy. The PU microparticles hollow inside have regular spherical shape with a diameter of 5-10 µm with a dense and smooth polymerics shell. The resulting polyimide–polyurethane (PI–PU) composites have high potential to regenerate damaged surfaces not only on the surface and also in the volume of composite within several minutes

Use of the modified technique of an antrotomy at treatment of patients with dontogenous maxillary sinuitis

More than 100 sick dontogenous maxillary sinuitis were studied. To all patients surgical treatment with use of a method of a osteo-plastic antrotomy of a genyantrum is lead. All patients have been taken on a dispensary observation. According to the lead postoperative computer tomography of additional sinuses of a nose in two projections, and also ortopantomography, rentgenographies of a facial skull in direct and lateral projections, endoscopic research, the pneumatization of the operated genyantrums has not been disturbed, the osteal forward wall has been kept on all extent, was absent retraction soft tissues of infraorbital area, that as a whole speaks about efficiency and not so traumaticaly the lead surgical treatment. The offered way of surgical treatment promotes to the greatest degree to conservation of anatomic structures of maxillofacial area, possessing the least traumatism in comparison with other ways. This technique is simple, effective and does not demand application of the expensive equipment

New technologies in treatment of patients with the got defects and deformations of a facial skull

More than 15 patients with the isolated fracture of the bottom wall of an orbit as «blow-out» were studied. As one of variants of an individual approach to restoration of the isolated defects of the bottom wall of an orbit we had been offered a technique of a osteo-plastic antrotomy, as a stage of access. All patients have been taken on a dispensary observation. According to the lead postoperative computer tomography of additional sinuses of a nose in two projections, and also ortopantomography, rentgenographies of a facial skull in direct and lateral projections, endoscopic research, the pneumatization of the operated genyantrums has not been disturbed, the osteal forward wall has been kept on all extent, was absent retraction soft tissues of infraorbital area, integrity of an osteal wall of a bottom of an orbit has been restored, that as a whole speaks about efficiency and not so traumaticaly the lead surgical treatment. The offered way of surgical treatment promotes to the greatest degree to conservation of anatomic structures of maxillofacial area, possessing the least traumatism in comparison with other ways. This technique is simple, effective and does not demand application of the expensive equipment
