Three dimensional (3D) electric conducting porous structures are a promising platform that could be utilized in emerging 3D structural electronics, energy storage systems, and biomedical applications. A poly(3,4-ethylenedioxythiophene)/silica (PEDOT/SiO2) composite with foam-like conducting open skeletal structures and pore sizes exceeding 100 μm is presented. A two-step procedure was used to prepare...
We develop an advanced electrospinning process that uses an electrostatic spiral collecting coil and a converging coil to produce a polyacrylonitrile (PAN) polymer fiber with a nanometer-sized diameter. The electrostatic spiral collecting coil was used as a collector on which to deposit a continuous and aligned PAN polymer fiber, and the converging coil was used to adjust the collecting area of the...
Thickness-dependent ordering of lamellar microdomains in symmetric polystyrene-b-poly(methyl methacrylate) (PS-b-PMMA) thin films was studied using scanning force microscopy (SFM), scanning electron microscopy (SEM), and grazing incidence small-angle X-ray scattering (GISAXS). The extent of perpendicular orientation for the lamellar microdomains on a neutral substrate was assessed at various film...
Pressure dependence of various phase transitions for the miscible block copolymer (BCP) blends was evaluated by depolarized light scattering (DPLS) and small-angle neutron scattering (SANS) measurements, in which the blends consist of a polystyrene-b-poly(n-butyl methacrylate) (PS-b-PnBMA) and a deuterated polystyrene-b-poly(n-hexyl methacrylate) (dPS-b-PnHMA). Excellent baroplasticity was observed...
New EL polymers possessing both hole and electron-transporting units in the main chain are synthesized. The polymer prepared by palladium catalyzed Heck reaction of 10 and 15 show a large weight average molecular weight (M w ) (25,000) and small polydispersity index (PDI) (1.2). The oligomers synthesized by Wittig condensation have M w of 4000 and PDI of 1.8. All the polymer and oligomers...
