A kölcsönhatás módosítása polipropilén - Rétegszilikát nanokompozitban

Research output: Review article


A major problem of nanocomposites is that their strength remains below the expected value. The silicate must be surface treated to increase the distance between its galleries and facilitate exfoliation. However, treatment leads to low interaction with the matrix. Recently several attempts were made to improve adhesion between the treated silicate and the polymer matrix by the introduction of a modified polymer. The maleinated polymer is claimed to improve intercalation through interdiffusion. However, the maleic anhydride group cannot react with the surface of the filler chemically, moreover, the surface is covered by the organic cation, usually a quaternary ammonium ion. Our goal was to find an answer to the questions raised above. Model reactions were carried out with maleinated polypropylene and various compounds used for the treatment of layered silicates. The reaction was followed by FTIR spectroscopy and DSC measurements. The results indicate that maleinated PP and the amine surfactant react with each other with the formation of imides. The study continues in order to determine the mechanism of interaction between the modified polymer and the filler.
