The purpose of the project is: "To establish and justify experimentally the possibility of PAN -fibers reaction-based modification using hydrogen peroxide in presence or absence of reducing agents. "Sorption nanotechnology using geterocoagulation mechanism of dyes, polymers and low molecular weight compounds functionalized surface with PAN - fibers. "To investigate the physical and chemical properties of functionalized PAN fiber . Research Methods - Chemistry and Physics of Macromolecular colloid chemistry, chemical dyes, nanotechnology, chemical engineering of fibrous materials. Results and novelty: experimentally established the reaction-based modifying possibility of PAN -fibers using hydrogen peroxide in presence or absence of reducing agents agent; experimentally established the possibility of creating fibrous materials with controlled properties by applying layers of colloidal particles on the surface of the fibers using a geterocoagulation process within nanotechnology and surface properties modification of PAN fibers using geterocoagulation within nanotechnology may lead to fundamentally new and important in the practical use of the properties of PAN - fibers. Practical significance : 1) the effect of functionalization conditions (temperature, hydrogen peroxide concentration , pH f functionalization bath ) on the surface of the fibrous nature on the basis of PAN was investigated; 2) the thermodynamics of dyeing with cationic dye PAN - fibers treated without Lewis approach to solutions; 3) a system "PAN - fiber - dyeing bath" is being watched with taking into consideration the presence of nanodimensional interfacial layer of variable thickness properties; 4) the chemical potential of the dye in solution is described using the value of the molar partial enthalpy change of the dye; 5) considered PAN fibers dyeing with cationic dye as in a non-aqueous solution; 6) the analysis of the reaction-based modification impact on the surface condition of fibrous material based on copolymers of acrylonitrile was conducted; 6) experimentally proved that as a result of functionalization changes the interfacial layer boundaries vapor / solid. Basic design and engineering and technical performance and parameters. When doing research received 1 patent for utility model Pat. (UA) 47 816 , IPC D06R 1/ 00. Apply for a patent for utility model № V 201314117. Degree of implementation : the work is fundamental. The results were tested in the company of " FIM " (the act of production test of 10 January 2013). Materials are used in lecture courses , "Chemical Technology of Textile Materials ", " Physics-Chemistry of dyeing" for the students of specialty 6.051301 Chemical Engineering. Faculty - Textile chemicals and finishing production, as reflected in the educational program (Act implementation in the scientific process from 27.02 . 2013) Relations to other work : work is done in the field of nanotechnology , as the process is carried out in nanolayers. Recommendations for the use of work. Fundamental work has theoretical and practical application. This paper shows the possibility of significant improvement in consumer properties of yarn and knitted fabric based on copolymers of acrylonitrile: an increase in hydrophilicity, reducing electrified (by increasing the conductivity of the surface layer) during the Radzyshevskyi reaction. The results of research are to be used in factories producing woolen yarn and artificial fur using fiber -based copolymers acrylonitrile Field of use: finishing light industry . Economic performance: exclusion of static-handling operation for PAN fibrous materials in the process of finishing , improved hygienic properties by increasing hydrophilicity. Conclusions and proposals. For the research development it is reasonable to conduct further elaborationt of the subject, the estimated topics - applied research to ensure the implementation into the industry. The affinity of cationic dyes, unctionalization, PAN- fiber materials , thermodynamics wettability, antistatic PROCESSING , hydrogen peroxide . Product Description popup.authors Бардаш Н.О.
