摘要

The composite nanomaterial consisting of an acrylic paint and multiwalled carbon nanotubes (~ 3 wt.%) was investigated. The samples had a disk shape with a diameter of 20-30 mm and a thickness of 0.005-1.5 mm. It was established that the samples exposed in water for 250 h almost did not lose their mass (a mass loss was smaller than 1.6%) and their electrical conductivity was highly stable. After long-term(over 100 h) annealing at temperatures of 90-145 °C, the conductivity of the composite increased by a factor of 300-1000 and attained its maximum value of about 1000 S/m. The investigated nanomaterial is promising for application in various devices, including electrodes for biomedical engineering or wearable electronics.
