Fabrication of CuTAPc polymer nanowires and nanotubes by electropolymerization

Studies on CuTAPc-nanotube-modified electrodes as chemical sensors for NO

Poly-copper tetraaminophthalocyanine (CuTAPc) nanotubes were successfully fabricated on porous alumina templates by electropolymerization. Their high surface area and simple preparation protocol made them potential candidates as the modification layer of electrodes for sensor application. High sensitivities and improved linear ranges were obtained through different measurements such as differential pulse voltammetry (DPV), differential potential amperometric (DPA) and electrochemical impedance spectroscopy (EIS). Detection limits as low as 10 nM were demonstrated in common voltammetric analysis with ultra-high response current in the microA range.

Fabrication and Field Emission Properties of Poly-CuTAPc Nanowires and Nanotubes

Poly-copper tetraaminophthalocyanine (CuTAPc) nanowires and nanotubes were successfully fabricated on porous anodic aluminium oxide (AAO) templates by electropolymerization and characterized. The product of electropolymerization, whether as nanowires or nanotubes, is a function of the monomer concentration and template pore size. The morphology and field emission properties of these nanostructures were studied for investigation of potential application as field emitters. They show interesting turn-on field, maximum current density and enhancement factor, comparable to many other organic nanomaterials.
