Lay Summary (English)

Lead
Lay summary
Carbon nanotubes (CNTs) are considered to be very promising for many applications due to their exceptional physical properties. For example, they are lighter but stronger than steel and can support current densities by orders of magnitude higher than conventional metallic wires. The aim of this project is to fabricate composites of carbon nanotubes and functional polymers (for example epoxy-based SU8 resin or Poly(dimethylsiloxane)) for MEMS (Micro-Electro-Mechanical Systems) and microfluidic applications (manipulation of liquids and gases in channels having cross sectional dimensions of the order of 10-100?m). The benefit of mixing CNTs, in a polymer matrix, for example SU8, would be i) improved thermal management of MEMS devices (nanotubes are excellent thermal conductors); ii) reduced brittleness of the matrix (CNTs are elastic); and iii) minimised the electrical charging effects due to the high electrical conductivity of the CNTs. The challenges we face in order to achieve such high performance composites are 1. Tuning the CNTs synthesis for a narrow diameter distribution and high structural quality; 2. Cutting the nanotubes to an optimal length in order to improve their dispersion in the matrix; 3. Functionalizing their surface to achieve better wetting and dispersion. We offer solutions to all of the above mentionned items. Furthermore, within this project we will explore the mechanical, thermal, and electronic properties of the resulting composites. We foresee the fabrication and performance testing of MEMS and microfluidic devices based on our CNTs/polymers composites.
