“…This process is possible on any kind of organic surface having available hydrogens for abstraction, including the already grafted chains, allowing for branched or even crosslinked polymer films. The method can be used for grafting polymers onto surfaces that are relatively inert, or otherwise hard to functionalize, such as polyethylene 57,58 , carbon nanotubes 59,60 , hexagonal boron nitride 61 , or graphene 62 . The technique was recently used to graft onto cellulose nanocrystals 63 , to improve the device capabilities of perovskite quantum wells 64 , and during the synthesis of metal-organic frameworks 65,66 .…”

“…Conductive carbon nanotube/polymer composites also have other so-called technological properties, such as thermoelectric power generation or shape memory. Thus, embedded carbon nanotubes enabled the respective CNT/composite materials to be used as thermopiles [ 25 ], actuators [ 26 , 27 ], parts of field-effect transistors [ 28 , 29 ], etc.…”

A novel microstrip resonant vapor sensor made from a conductive multiwalled carbon nanotubes/ethylene-octene copolymer composite, of which its sensing properties were distinctively altered by vapor polarity, was developed for the detection of organic vapors. The alteration resulted from the modified composite electronic impedance due to the penetration of the vapors into the copolymer matrix, which subsequently swelled, increased the distances between the carbon nanotubes, and disrupted the conducting paths. This in turn modified the reflection coefficient frequency spectra. Since both the spectra and magnitudes of the reflection coefficients at the resonant frequencies of tested vapors were distinct, a combination of these parameters was used to identify the occurrence of a particular vapor or to differentiate components of vapor mixtures. Thus, one multivariate MWCNT/copolymer microstrip resonant sensor superseded an array of selective sensors.

“…However, currently this is hardly possible in mass production processes at the wafer level. Multiple productions steps like etching and plasma treatments favor the subsequent creation of defects [8][9][10][11][12], which have a large influence on the device performance [13,14]. Consequently, it is of great interest to know the impact of defects on the electronic structure and transport properties.…”

We investigate the electronic transport properties of semiconducting (m, n) carbon nanotubes (CNTs) on the mesoscopic length scale with arbitrarily distributed realistic defects. The study is done by performing quantum transport calculations based on recursive Green's function techniques and an underlying density-functional-based tight-binding model for the description of the electronic structure. Zigzag CNTs as well as chiral CNTs of different diameter are considered. Different defects are exemplarily represented by monovacancies and divacancies. We show the energy-dependent transmission and the temperature-dependent conductance as a function of the number of defects. In the limit of many defetcs, the transport is described by strong localization. Corresponding localization lengths are calculated (energy dependent and temperature dependent) and systematically compared for a large number of CNTs. It is shown, that a distinction by (m−n)mod 3 has to be drawn in order to classify CNTs with different bandgaps. Besides this, the localization length for a given defect probability per unit cell depends linearly on the CNT diameter, but not on the CNT chirality. Finally, elastic mean free paths in the diffusive regime are computed for the limit of few defects, yielding qualitatively same statements.
