Abstract

Способ получения наномодифицированных полимерных материалов, включающий конденсацию паров мономера, отличающийся тем, что вещество мономер предварительно нагревают до температуры кипения, далее пары мономера подают в газовый канал, тем самым создавая первый двухфазный поток, включающий газ и пары мономера, затем первый двухфазный поток подают в камеру смешения, одновременно во второй газовый канал подают охлажденные до температуры не менее 0°C наночастицы, создавая тем самым второй двухфазный поток, который также подают в камеру смешения одновременно с первым двухфазным потоком, а конденсацию паров мономера на наночастицах получают в камере смешения, устанавливая температуру стенок которой не ниже температуры кипения мономера, процесс смешения двух двухфазных газовых потоков осуществляют не менее 0,1 с, в результате чего получают конденсат частиц мономера на поверхности наночастиц, который далее полимеризуют до твердого состояния.A method for producing nanomodified polymeric materials, including the condensation of monomer vapor, characterized in that the monomer substance is preheated to the boiling point, then the monomer vapor is fed into the gas channel, thereby creating the first two-phase flow, including gas and monomer vapor, then the first two-phase flow is fed into the mixing chamber, at the same time nanoparticles cooled to a temperature of at least 0°C are fed into the second gas channel, thereby creating a second two-phase flow, which is also fed into the mixing chamber simultaneously with the first two-phase flow, and condensation of the monomer vapor on the nanoparticles is obtained in the mixing chamber by setting the temperature of the walls of which is not lower than the boiling point of the monomer, the process of mixing two two-phase gas flows is carried out for at least 0.1 s, as a result of which a condensate of monomer particles is obtained on the surface of the nanoparticles, which is then polymerized to a solid state.
