Abstract

Specific conductivity of the composite nanomaterial layers with micron and submicron dimensions, consisting of carboxymethyl cellulose (CMC) and multiwalled carbon nanotubes (MWCNT) was investigated. Ultradispersed aque ous suspension was deposited on soft (aluminum foil, plates made from polyester and polyimide, cotton fabric, office paper) and solid (coverslip, silicon wafers with silicon oxide layer) substrates by silk-screen printing. Electrical resis tance was measured by four-probe method and by the method of square on surface from which the conductivity and conductivity per square of surface were calculated taking into account layer’s geometric dimensions. Specific conduc tivity of the layers with thickness range 0.5 - 5 μm was ~1.2 ×10 4 ÷4 ×10 4 S/m , and max conductivity per square was ~ 0.2 S. Investigated nanomaterial is attractive to electronic and biomedical applications.
