Formation of carbon sp3 hybridization bonds in local electric fields of composites “polymer-CNT”

Liudmyla Karachevtseva; Mykola Kartel; Wang Bo; Yurii Sementsov; Viacheslav Trachevskyi; Oleg Lytvynenko; Volodymyr Onyshchenko

Volume 9, Issue 4 , April 2018, , Pages 296-300


  Carbon nanotubes are among the most anisotropic materials known and have extremely high values of Young's modulus. The possibilities to enhance the properties of nanostructured surfaces were demonstrated on “polymer-multiwall carbon nanotube” composites. Influence of sp < sup > 3 hybridization ...  Read More

Liudmyla A. Karachevtseva; Mykola T. Kartel; Oleg O. Lytvynenko; Volodymyr F. Onyshchenko; Kostyantyn A. Parshyn; Olena J. Stronska

Volume 8, Issue 4 , April 2017, , Pages 336-341


  We synthesized light-emitting coatings of CdS nanocrystals in polyethyleneimine and polyethyleneimine with multiwall carbon nanotubes on macroporous silicon. The photoluminescence of CdS nanocrystals in polyethyleneimine on oxidized macroporous Si is more intense in comparison with substrates c-Si, macroporous ...  Read More

B. V. Mohan Kumar; R. Thomas; A. Mathew; G. Mohan Rao; D. Mangalaraj; N. Ponpandian; C. Viswanathan

Volume 5, Issue 9 , September 2014, , Pages 543-548


  Multiwall carbon nanotubes (MWCNT) are synthesised by cost effective method of pyrolysing xylene (as hydrocarbon, precursor) in the presence of ferrocene (as catalyst) at 750 o C. The so obtained MWCNTs has a length ranging from 90 µm to 300 µm and diameter ranging from 20 nm to 200 nm depending ...  Read More

Structure And Catalytic Activity Relationships Of Fe/Co Supported On Different Sources Of Al(OH)3 in The Production Of Multiwall Carbon Nanotubes By Catalytic Chemical Vapour Deposition Method 

H. Kathyayini;N. Nagaraju

Volume 3, Issue 4 , September 2012, , Pages 309-314


  Al(OH)3 from different sources has been used as supports for a mixture of Fe/Co salts and employed in the synthesis of Multiwall Carbon nanotubes by Catalytic Chemical Vapour Deposition method. These supported-catalysts have been characterized by Scanning Electron Microscopy, Powdered X-ray diffraction, ...  Read More
