On the Presence of Carbon Nanotubes During Streaming Potential Measurements in Microfluidics

Alignment of carbon nanotubes (CNTs) has been studied in details for the past decades. In this paper, we examine the presence of single wall carbon nanotubes on experimental microfluidic systems during streaming potential measurements. The PMMA surface modified by CNTs has been characterized by high resolution scanning electron microscope (SEM), contact angles and streaming potential measurements. Preliminary results demonstrate clearly the effect of CNTs on microfluidic experiments in terms of streaming potentials.
