Outline of Final Research Achievements

We prepared sulfated sugar pendant polymer with various molecular weight, which we used as poly(3,4-ethylenedioxythiophene) (PEDOT) dopants. PEDOT/ sulfated sugar pendant polymer films were prepared via in situ chemical oxidative polymerization of 3,4-ethylenedioxythiophene (EDOT) in an aqueous solution of sulfated sugar pendant polymer, followed by spin-coating. We investigated the heat ray absorption of the PEDOT/ sulfated sugar pendant polymer films as a function of their molecular weight. The PEDOT film fabricated using sulfated sugar pendant polymer (Mw = 28000) showed the highest heat-ray absorption.
The enhancement of heat ray absorption of PEDOT film was attributed to the decrease of molecular weight of sulfated sugar pendant polymer.
