The scientific-technical journal

It is the scientific-technical journal in English in Ukraine discussing actual problems of chemistry and chemical technology. Compared with other chemical journals Ch&ChT is publishing materials of both theoretical and practical values in such fields as analytical, general organic, physical and inorganic chemistry; chemistry of high molecular compounds; materials science and engineering; chemical kinetics and catalysis; technology of inorganic substances; technology of organic synthesis products; chemical technology of processing of combustible minerals; processes and apparatus of chemical and food productions; biotechnology and ecology.

    Structure formation synergetics and properties of polypropylene/carbon nanotube nanocomposites
    (Publishing House of Lviv Polytechnic National University, 2012) Kozlov, Georgiy; Zaikov, Gennady
    It has been shown that aggregation (tangled coils formation) of carbon nanotubes begins at their very small contents. This factor strongly reduces reinforcement degree of polymer/carbon nanotube nanocomposites. Estimation of the main parameters that influenced elasticity modulus of the mentioned nanocomposites was fulfilled. Theoretical calculations showed high potential of nanocomposites filled with nanotubes. Показано, що агрегація (утворення переплутаних клубків) вуглецевих нанотрубок починається при дуже малому їх вмісті. Цей чинник значно понижує ступінь підсилення нанокомпозитів полімер/вуглецеві нанотрубки. Проведено оцінювання основних параметрів, які впливають на модуль пружності вказаних нанокомпозитів. Теоретичні розрахунки показали високий потенціал нанокомпозитів, наповнених нанотрубками.
