Influência da deposição de filmes finos organosilicones na fotodegradação do polipropileno
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-So, 2013-07-31)
It is known that polypropylene is degraded in the presence of UV radiation, making difficult its use in applications where occurs this kind of radiation. This situation arises a need to improve the properties of polypropylene ...
Organosilicon films deposited in low-pressure plasma from hexamethyldisiloxane — A review
(2021-12-01)
We present a review of low-pressure plasma-enhanced chemical vapor deposition (PECVD) with the hexamethyldisiloxane (HMDSO) precursor for production of organosilicon thin films. This topic has been the subject of numerous ...
Desenvolvimento de filmes finos de organosilicone depositados a plasma para fotoproteção do polipropileno
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2019-02-26)
Polypropylene (PP) is a polymer used industrially on a large scale. However, the PP has limitations in external use due to its sensitivity to photodegradation, when exposed to the elements. This limits the options of use ...
Role of the plasma activation degree on densification of organosilicon films
(2020-01-01)
The possibility of controlling the density of organosilicon films was investigated by tuning the plasma activation degree without providing extra energy to the structure, as usually reported in the literature. For this ...
Delineação de padrões na superfície da poliamida por processo de plasma
(Universidade Estadual Paulista (Unesp), 2016-11-17)
Neste trabalho foi investigada a possibilidade de se criar padrões regularmente distribuídos sobre a superfície da poliamida (PA), utilizando o processo de deposição de filmes em plasmas de baixa pressão. Para tal, um único ...
Enhancement of Corrosion Resistance AISI 304 Steel by Plasma Polymerized Thin Films
(2013)
The purpose of this work is the deposition of films in order to increase the corrosion resistance of AISI 304 steel, which is a material used to construct the reactors for bioethanol production. This deposition inhibits ...
