Mechanical Routes To Biocontinuous Conductive Polymer Networks For Solar Cell Applications, Erin Waterman

Honors Theses

We have successfully created the first example of a bicontinuous conductive polymer network for use in hybrid QD-polymer solar cells via a mechanochemical route. Heterometallic dicyanoaurate coordination polymers were used as intercalative hosts to promote in situ growth of emeraldine polyaniline (PANI), which provides electron conduction pathways within the active layer. Cu2+-excanged Laponite RD nanodiscs were used to direct the self-assembly of the bicontinuous polymer networks and nanomorphology within the nanocomposites. These PANI/Laponite coordination polymers were extensively characterized by scanning electron microscopy, attenuated total reflectance-Fourier transform infrared spectroscopy, and ultraviolet-visible absorption spectroscopy in order to probe polymer-nanoparticle and polymer-polymer interactions. …
