TUBALL single-walled carbon nanotubes (SWCNT) by OCSiAl, an international nanotechnology company, have better potential in the production of electroactive polymers, as compared to other multi-walled nanotubes (MWCNT), according to a series of research tests.

The research tests were conducted by Dresden University of Technology, a German polytechnic university, in cooperation with Fraunhofer IWS, a German research organization, to measure dependency of specific resistivity on the additive concentration of SW- and MWCNTs in samples of basic polymer DowCorning Sylgard 184.

According to the results, resistivity of the poymer sample with multi-walled nanotubes increases, while TUBALL nanotubes show a resistivity drop, which is better. Also as higher concentrations of multi-walled nanotubes are required to reach the same values of resistivity that can be obtained with TUBALL, to achieve the same benefit significantly less TUBALL is required when compared to other types of carbon nanotubes.

The researchers also noted that the positive effects for other properties in other samples are much stronger with TUBALL.

The demand for polymers and adhesives with specific properties for industrial applications is growing substantially. Features like low specific resistance are crucial for the efficient applications and productivity. One of the ways to achieve the required values is to modify the basic polymer with CNT-based additives, and TUBALL provides the most optimal results, according to the research.

TUBALL single-walled carbon nanotubes are also used for the production of modified elastic conductive paths, conductive sealing, and jointing materials. (GK)
