ABSTRACT: We describe a
new method for transparent and conductive films based on carbon nanotubes and
bovine serum albumin composite development. Films are deposited from an aqueous
solution of carbon nanotubes/bovine serum albumin by drop-coating and
rod-coating methods. Sheet resistances of as-prepared films vary from 200
Ohm/sq with 50% transmittance to 30 KOhm/sq
with 90% transmittance. The maximum sdc/sop ration found in
this work is 2.27, which gives
a DC conductivity of 4.55 × 104 S·m－1. Atomic force microscopy and Raman spectroscopy studies of the films
show that the process of film formation produces neither structural nor
chemical changes in the nanotubes. Possibility of using these films for cell culturing is tested on human embryonic fibroblast cell line. Therefore, it is first
time ever in literature, when proposed a method, allowing fabricating at the
same time transparent, high-conductive and biocompatible CNT films.
