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.

    The structural model of impact toughness of particulate-filled polymer nanocomposites
    (Publishing House of Lviv Polytechnic National University, 2011) Kozlov, Georgiy; Aphashagova, Zarema; Malamatov, Akhmed; Zaikov, Gennady
    A quantitative structural model of particulate-filled polymer composites impact toughness, based on the fractal analysis ideas, was offered. The model demonstrated good correspondence with the experimental data. It has been shown that the action of nanofiller as nucleator, resulting in crystallinity degree and amorphous phase structure change, exert the main influence on impact toughness value. Запропоновано кількісну структурну модель ударної в’язкості дисперсно-наповнених полімерних наноком-позитів на основі уявлень фрактального аналізу. Вказана модель добре узгоджується з експериментальними даними. Показано, що основний вплив на величину ударної в’язкості має дія наповнювача як утворювача зародків, що призводить до зміни ступеня кристалічності і структури аморфної фази.
