Polymeric Nanocomposites Enabled by Controlled Architecture Materials, 2005 PLACE Conference

PressWeb.jpg

Controlled architecture materials (CAMs) (i.e. block copolymers) are being explored as specialty additives for the formation of polymer nanocomposites under melt-processing conditions. These block-copolymer-based additives provide interesting exfoliation solutions for clays of differing hydrophobicity in a variety of polymers. In this paper we demonstrate the ability of CAMs to exfoliate both organically modified and unmodified natural clays in polystyrene (PS) and polypropylene (PP) resins. Complementary characterization techniques of Transmission Electron Microscopy (TEM), x-ray diffraction (XRD), and rheology are used to identify exfoliation. Additionally, we demonstrate the efficiency of CAMs to exfoliate clay at low additive levels.
