Abstract

Solid layers of PEDOT–detonation nanodiamond based nanoparticles with an exceptional structural order were produced by means of a template-free polymerization technique. As an efficient multifunctional filler, the nanocrystalline diamond has been shown to possess a high catalytic activity on the monomer polymerization rate as well as to play a fundamental role as a 3D arrangement-directing agent of the PEDOT chains at the micro- and nano-scale. SEM, TEM and TED analyses highlighted the mutual organization between PEDOT oligomers and nanodiamond grains, and the produced hierarchical effects on the arrangement of the backbones of the final polymer. Optical and Raman spectroscopy, used together with XRD diffraction to study the molecular structure and crystallographic features of the hybrid materials, pointed out that the adopted synthetic strategy enables highly conjugated and doped hybrid systems to be generated. The spatial distribution of the filler inside the polymeric matrix and the mutual connectivity of nanodiamond crystals and PEDOT segments are found to strongly improve the functional properties of the host polymer. Mechanical characterizations by advanced AFM-based techniques revealed that both indentation modulus and hardness of PEDOT/nanodiamond materials are 3 times higher than the pure PEDOT polymer, while electrical characterizations by a 4-probe method gave sheet resistance values of 1 106 U sq 1 for the nanocomposite particles
