Maximum ionic conductivity values of 4.95 × 10−5 S cm−1 at ambient temperature and 1.64 × 10−3 S cm−1 at 80 °C with 10 wt % content of surface modified PZS nanotubes were obtained and the lithium ion transference number was 0.41.
The dispersive surface energies, γd, of the as-received and modified carbon nanotubes were found to be very similar while the specific surface energies differed significantly, contributing between 10% and 30% to the total surface energy, depending on the modification treatment.
The influence of structural, morphological and surface properties on photocatalytic activity of pristine and modified titanate nanotubes was carefully described and discussed in the following study.
A highly sensitive sensor for the determination of nickel, not only in environmental samples but also in food, is based on modified nanotubes and has a detection limit of 4.9 ng L−1 [102].
Afterwards the nanotubes were modified with catalytically active films of iron porphyrin (FeTMPP-Cl) or iron phenanthroline (Fe phen 3) through a pulsed potential deposition technique.
Catalytic multi-walled carbon nanotubes were modified by KOH activation at 800 °C and/or ammoxidation at 350 °C, and the effect of these treatments on the physicochemical and electrochemical properties was investigated.
In order to penetrate the cell membrane, the nanotubes were modified with phospholipids.
Well-defined TiO2-V2O5/C nanostructures modified by multi-walled carbon nanotubes were synthesized by a hydrothermal strategy.
Carbon nanotubes were covalently modified with PEI by following the direct amination procedure in the literature [29, 30].
Graphene oxide and multiwall carbon nanotubes were chemically modified by treatment with an aniline derivate or by incorporating nitrogen-adatoms.
