Carbon nanotubes (CNTs) and related nanocomposite material for multiple applications

For an excellent global OVERVIEW of CNT research including why CNT is undoubtedly the ULTIMATE nano-material in nanotechnology today, please visit

Here's my research on carbon nanotubes ...

(1) Alignment of CNTs in polymer matrix composites, by promotion of shear flow of the polymer matrix.

(2) Identification and characterization of the CNT-polymer interface formed, due to intimate contact between the CNT and polymer.

(3) Full and fast (in minutes) densification of CNT-titania and CNT- hydroxyapatite (HA) composites using the innovative spark-plasma sintering method.

(4) Synthesis of aligned CNTs (from unsupported nanosized Fe) by catalytic chemical vapour deposition (CCVD), using ferrocene as an organometallic precursor.

(5) Diameter-controlled synthesis (high-yield) of entangled CNTs by CCVD, by alteration of the catalyst active nanoparticle size (supported nanosized metal) or carbon deposition temperature.

(6) Synthesis (high-yield) of entangled CNTs by CCVD, using a variety of stoichiometrically formulated oxide(s)-ceramic supported nanosized metal powder catalysts: Ni and Co dispersed on alumina, silica, halfnia stabilized zirconia, magnesia, titania, tri-calcium phospate (TCP) and hydroxyapatite (HA).

(7) Purification of as-synthesized CNTs.

(8) Experimental verification of the inverse relationship between curvature strain energy of the CNT wall and its diameter, using X-ray diffraction (XRD).
