1,3-dioxolane: A green solvent for the preparation of carbon nanotube-modified electrodes
(Elsevier Inc., 2014)
One of the main challenges associated with the handling of carbon nanotubes (CNTs) for modifying electrodes is the production of adequate dispersions. We report the first example in which 1,3-dioxolane was used to produce ...
Different dispersion states of MWCNT in aligned conductive electrospun PCL/MWCNT composites
(Taylor & Francis, 2018-10)
This work presents the synthesis and characterization of oriented nanofibers made of polycaprolactone (PCL) and multiwalled carbon nanotubes (MWCNT) obtained by electrospinning. The preparation of MWCNT/PCL solutions and ...
Compósito piezoelétrico trifásico baseado em poliuretano de óleo de mamona com partículas de PZT e nanotubos de carbono de paredes múltiplas
(Universidade Estadual Paulista (Unesp), 2021-08-04)
Materiais capazes de modificar ou alterar suas propriedades sobre a ação de um estímulo externo são classificados como inteligentes. Dentre esses materiais, confeccionados para atender exigências específicas para a finalidade ...
Using photosensitive dye to improve multi walled carbon nanotubes dispersion
(Institute of Physics Publishing, 2011-11)
As already well-known, the outstanding mechanical and electrical properties of carbon nanotubes (CNT) are partially lost when CNT aggregate. The fact that CNT tend to aggregate makes difficult to put them into a host matrix, ...
Urea assisted hydroxyapatite mineralization on MWCNT/CHI scaffolds
(Royal Society of Chemistry, 2008-12)
Urea assisted hydroxyapatite (HAp) mineralization was performed on scaffolds composed of a major fraction of multiwall carbon nanotubes (MWCNT, 85 wt.%) and a minor one of chitosan (CHI, 15 wt.%). The MWCNT/CHI scaffolds ...
Avaliação das propriedades elétrica, dielétrica e piezoelétrica do compósito com conectividade 1-3 de poliuretano de óleo de mamona com bastões de PZT e MWCNT
(Universidade Estadual Paulista (Unesp), 2022-04-29)
Materiais capazes de alterar uma ou mais de suas propriedades quando submetido a um estímulo externo são classificados como inteligentes e entre essa ampla classe de materiais, destacam-se os compósitos piezoelétrico. Neste ...
Hydration of Portland cement modified by carbon nanotubes/surfactant dispersions
(Universidade Federal do Rio de JaneiroBrasilInstituto Alberto Luiz Coimbra de Pós-Graduação e Pesquisa de EngenhariaPrograma de Pós-Graduação em Engenharia CivilUFRJ, 2019)
Glassy carbon electrodes modified with multiwall carbon nanotubes dispersed in polylysine
(WILEY-V C H VERLAG GMBH, 2008-08)
We report the analytical performance of glassy carbon electrodes (GCE) modified with a dispersion of multiwall carbon nanotubes (MWCNT) in polylysine (Plys) (GCE/MWCNT-Plys). The resulting electrodes show an excellent ...
Promising PLA-functionalized MWCNT composites to use in nanotechnology
(John Wiley & Sons Inc, 2015-04)
Films based on polylactic acid (PLA) reinforced with multi-walled carbon nanotubes (MWCNT) were developed after using an excellent methodology to ensure an optimum dispersion of the filler in the matrix. The functionalization ...
