“…Unfortunately, polymeric cast films deposited on surfaces are susceptible to degradation by physical processes of abrasion, delamination or thermal expansion. 16 Furthermore, the conductivity of conjugated polymers in cast films is hindered due to the disturbed transport of charge carriers as macromolecules in bulk are disordered. Thus, there is a strong demand for formation of ordered or self-assembled polymer systems 17 that may be easily processed and exhibit high stability and conductivity.…”

Conductive polythiophene-based brushes grafted from an indium tin oxide substrate were fabricated as promising materials with directional conductivity for potential optoelectronic applications. The obtained brushes, thanks to their ordered structure and large conjugation length, exhibited high conductivity after chemical doping. Surface-initiated photoiniferter mediated polymerization of a 3-methylthienyl methacrylate monomer was used in the first step of grafting enabling formation of dense brushes. In the second step a self-templating approach that utilized oxidative polymerization of the pendant thiophene groups in the grafted multimonomer chains was used for the formation of ladder-like conjugated brushes. The polymerization conditions were optimized towards the largest possible effective conjugation lengths of the macromolecules. The rate of the undesirable spontaneous iodine dedoping process was followed for the first time using conductive atomic force microscopy. UV-VIS and grazing angle IR spectroscopy were applied to find correlations between various synthetic procedures and the conjugation lengths of the brushes. † Electronic supplementary information (ESI) available: Additional results of AFM measurements, grazing angle IR spectra, UV-VIS spectra, XPS spectra, estimations of the brush conductivity and a movie showing C-AFM images changing in time.

“…19 In the past few decades, to further improve the electronic performance of devices, numerous surface grafting polymers have been successfully used as different components of devices, such as insulating layer, conductive layer and semiconducting layer. 7,15,[20][21][22][23] With the rapid development of flexible electronics, surface-grafting polymers with natural flexibility and ambient stability have a great potential application value in flexible devices. In general, compared with other surface processing methods, surface grafting polymers possess several advantages: (i) tunable surface properties.…”

“…A finer degree of polymer structure and composition control has been achieved in hybrid materials for chromatographic applications. The potential for even more demanding applications, such as in the construction of optoelectronic devices [1], drives current research towards morphology control, and enhanced physical and chemical stability of the resulting material with efficient and stable charge exchange between the organic and inorganic components. In these respects, better performance from covalently attached polymer layers on inorganic surfaces is foreseen than from physisorbed layers.…”
