Thickness and Annealing Temperature Effects on the Optical Properties and Surface Morphology of Layer-by-Layer Poly(p-phenyline vinylene) plus Dodecylbenzenesulfonate Films
(WILEY-BLACKWELL PUBLISHING, INC, 2011)
The fabrication of controlled molecular architectures is essential for organic devices, as is the case of emission of polarized light for the information industry. In this study, we show that optimized conditions can be ...
Polarity studies of single polyelectrolyte layers in polyelectrolyte multilayers probed by steady state and life time doxorubicin fluorescence
(Elsevier, 2022-02)
Hypothesis: Polarity in polyelectrolyte multilayers (PEMs) may vary from the inner to the top layers of the film as the charge compensation of the layers is more effective inside the PEMs than in outer layers. Doxorubicin ...
Spray layer-by-layer films based on phospholipid vesicles aiming sensing application via e-tongue system
(Elsevier B.V., 2012-05-01)
The Layer-by-Layer (LbL) technique via spraying (spray-LbL) has been applied as new and alternative methodology to fabricate ultrathin films due to its versatility in relation to the conventional dipping-LbL method, mainly ...
Desenvolvimento de um biossensor bienzimático amperométrico para detecção de β-lactose através de filmes nanoestruturados layer-by-layer (LbL)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-So, 2014-02-28)
In this work the immobilization of enzyme β-Galactosidase has been investigated with use of assembly technique of nanostructured films denominated LbL (Layer-by-Layer) for employment in an amperometric biosensor of ...
Layer-by-Layer Films with CoFe2O4Nanocrystals and Graphene Oxide as a Sensitive Interface in Capacitive Field-Effect Devices
(2022-01-01)
Sensor devices have proved to be a promising technology for portable microelectronic systems for biomedical and environmental applications. Depending on the target analyte and/or the sensor platform chosen, the study of ...
Nanocompósitos eletroativos de poli-o-metoxianilina e polissacarídeos naturais
(Sociedade Brasileira de Química, 2007-10-01)
In this work we take advantage of the polyelectrolyte character of some Brazilian native gums to fabricate electrically conductive, nanostructured films. The gums Sterculia urens, (caraia), Sterculia striata (chicha) or ...
Modificação da interface de compósitos de polipropileno com fibras de vidro pela técnica Layer-by-Layer
(Universidade Federal de Minas GeraisUFMG, 2016-03-29)
The properties of glass fiber-reinforced polymer composites are closely related to the performance of the interface between fibers and polymer matrices. Many interfacial treatments have been developed and used to improve ...
Photocatalytic thin films containing TiO 2:N nanopowders obtained by the layer-by-layer self-assembling method
(2012)
In this work, TiO 2-N powders were synthesized by high-energy ball milling, using commercial titanium dioxide (TiO 2) in the anatase phase and urea to introduce nitrogen into TiO 2 in order to enhance their photocatalytic ...
