Polymer nanocomposites carbon nanotubes selection

A sensitive and selective electrochemical analysis of the OPs methyl parathion (MPT) and 4-nitrophenol (PNP) has been carried out using a new type p-NiTSPc/p-PPD coated carbon fibre microelectrode (CFME)," and tricresyl phosphate has been determined in aqueous samples and air using a copper nanoparticles and carbon nanotubes-based electrochemical sensor. Similarly, dimethyl methylphosphonate (DMMP) and ethanol vapours have been determined using a high-performance nanocomposite material based on functionalized carbon nanotubes and polymers coated on a surface acoustic wave (SAW) device. ...

A great number of reviews concerning selective aspects of fullerenes and carbon nanotube (CNT) chemistry and physics have been published. The fundamentals of carbon nanostructures connected with fullerenes and CNTs were summarized by Kratschmer [150], Dresselhaus et al. [151] and Bernholc et al. [152], The electronic and structural properties of CNTs were described by Mintmre et al. [153]. An overview of the synthesis and application of CNT-polymer nanocomposites can be found in recently published reviews [154-162] and in a comprehensive review with over 250 references cited in a tabular format [158]. Recent results on electrochemical formation of polymers containing fullerenes, and studies of their... 

The diverse characteristics of nanocomposites, such as thermal, electrical, electrochemical, and mechanical properties, stem from the appropriate selection of fabrication process conditions and material type/formulations. Apparendy, the properties of prepared nanocomposites are much different from those of pure polymers simply because interactions between diverse types of polymers and nanopardcles take place at a molecular level (Matusik et al., 2011). Halloysite nanotubes (HNTs) as the alternative of carbon nanotubes, due to their similar hollow tubular structures, have been... 

Guiver et al, 2002). An increase in H2/CO2 separation factor from 1.53 to 3.57 has been observed for membranes containing 40% zeolite (Khan et aL, 2010,2011). Enhanced performance has been achieved for nanocomposites based on Multiwalled Carbon Nanotubes (MWCNTs) in poly(bisphenol A-co-4-nitrophthalicanhydride-co-l,3-phenylene diamine) (PBNPI). Reduced d-spacing compared to the pure polymer has yielded H2 permeability of 14 Barrer, H2/CH4 selectivity of 8, and H2/CO2 selectivity of 6 at 15% of CNT(Wengeffl/.,2009).
