  2. 17. Surface Energy Patterning and Optoelectronic Devices Based on Conjugated Polymers

    Författare :Xiangjun Wang; Olle Inganäs; Henning Sirringhaus; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface energy modification; Patterning; Dewetting; Conjugated polymer; plastic solar cell; Low bandgap; Electron acceptors and donors; Physics; Fysik;

    Sammanfattning : The work presented in this thesis concerns surface energy modification and patterning of the surfaces of conjugated polymers. Goniometry and Wilhelmy Balance techniques were used to evaluate the surface energy or wettability of a polymer’s surface; infrared reflectionabsorption spectroscopy (IRAS) was used to analyse the residuals on the surface as modified by a bare elastomeric stamp poly(dimethylsiloxane) (PDMS).
