Low temperature synthesis and electrical properties of PbTiO3 thin films prepared by the polymeric precursor method
(Elsevier B.V., 2000-05-01)
Ferroelectric PbTiO3 thin films were successfully prepared on a Pt(111)Ti/SiO2/Si(100) substrate for the first time by spin coating, using the polymeric precursor method. X-ray diffraction patterns of the films indicate ...
Desenvolvimento e caracterização de filmes poliméricos de amido de milho com incorporação de fibras de bagaço de cevada
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2020-03-25)
Interest in the use of starch for biodegradable films is growing due to being a natural, renewable, abundant and low cost source. However, starch films generally have low values of mechanical properties. Thus, this work ...
LiNbO3 thin films prepared from a polymeric precursor method
(1997-12-01)
LiNbO3 thin films were prepared from polymeric precursor method by dip coating. The precursor films, deposited on Si(111) substrates, were heat-treated from 400°C to 900°C in order to study the heat treatment influence on ...
Obtenção de filmes finos de TiO2 nanoestruturado pelo método dos precursores poliméricos
(Sociedade Brasileira de Química, 2008-01-01)
This work focuses in optimizing setup for obtaining TiO2 thin films by polymeric precursor route due to its advantages on stoichiometric and morphological control. Precursor stoichiometry, synthesis pH, solids concentration ...
Crystallization and optical properties of CCTO thin films under pressure influence
(2012-08-20)
CCTO thin films were deposited on Pt(111)/Ti/SiO 2/Si substrates using a chemical (polymeric precursor) and pressure method. The pressure effects on the CCTO thin films were evaluated by XRD, FEG-SEM and optical properties. ...

Assessment of different plasticizer – polyhydroxyalkanoate mixtures to obtain biodegradable polymeric films
The elaboration of films from biodegradable polymer polyhydroxybutyrate was studied with 4 main plasticizers at variable concentrations: polyethyleneglycol, lauric acid, glycerol and epoxidized soy bean oil. An evaluation ...
Flexible electrically conductive films based on nanofibrillated cellulose and polythiophene prepared via oxidative polymerization
(2019-09-15)
Industrial ecology, sustainable manufacturing, and green chemistry have been considered platform‐based approaches to the reduction of the environmental footprint. Recently, nanofibrillated cellulose (NFC) has gained ...
