Title: | Study of the nanomorphology of OC1C10-PPV/precursor-PPV blends by solid state NMR relaxometry | Authors: | ADRIAENSENS, Peter DAMS, Roel LUTSEN, Laurence VANDERZANDE, Dirk GELAN, Jan |
Issue Date: | 2004 | Publisher: | ELSEVIER SCI LTD | Source: | POLYMER, 45(13). p. 4499-4505 | Abstract: | Films of conjugated polymer blends were studied by NMR relaxometry in order to improve the understanding of the nanomorphology and segmental chain mobility. Whereas optical microscopy was applied to obtain a rough impression about the surface morphology, the T-1H and T-2H NMR relaxation decay times were determined in the solid state (C-13-CP/MAS and H-1-wideline NMR) to judge the homogeneity of the phase morphology, to estimate the size of phase separated molecular domains and to compare the local segmental chain mobility. Besides blend composition, important parameters investigated are the film processing technique (dropcasting vs. spincoating), the casting solvent and the casting substrate. (C) 2004 Elsevier Ltd.
