Light-Controlled Conductance Switching in Azobenzene-Containing MWCNT–Polymer Nanocomposites

We report on reversible light-controlled conductance switching in devices consisting of multiwalled carbon nanotube (MWCNT)–polymer nanocomposites blended with azobenzene molecules and photoisomerization of the latter. Both the azobenzene molecules and MWCNT, which are functionalized with carboxyl g...

description We report on reversible light-controlled conductance switching in devices consisting of multiwalled carbon nanotube (MWCNT)–polymer nanocomposites blended with azobenzene molecules and photoisomerization of the latter. Both the azobenzene molecules and MWCNT, which are functionalized with carboxyl groups (MWCNT-COOH), are embedded independently in a poly­(methyl methacrylate) matrix, and thin films are prepared by using a simple spin-coating technique. We demonstrate the feasibility of the present concept with a photocurrent switching amplitude of almost 10%.
