Compatibilização química em compósitos de PLA reforçados com fibras de sisal
(Universidade Federal de São Carlos, 2018-07-13)
Even though poly(lactic acid) (PLA) is fragile under impact and has low toughness, the polymer stands out for its stiffness and high tensile strength. This polymer is an interesting material not only for short-term ...
Nanocompósitos de poliuretano comercial e nanopartículas híbridas de núcleo Fe3O4 funcionalizado com capa orgânica de Poli(1,4-Butanodiol)
(Universidade Federal de São Carlos, 2018-02-23)
The use of inorganic nanoparticles in polymer nanocomposites allows gain in mechanical resistance and new properties. However, the incorporation of organic layer functionalized nanoparticles alters the material’s properties ...
Preparação, caracterização e otimização de biocompósitos poliméricos comestíveis reforçados com fibras vegetais
(Universidade Federal de São Carlos, 2017-05-19)
The ever-growing environmental concern arising from the unrestricted exploitation of fossil raw materials for the massive production of non-biodegradable materials, guided by the rapid increase in the world population as ...
Vitrocerâmicas condutoras de íon lítio com estrutura do tipo Nasicon baseadas no sistema Li1+X CrX (GeY Ti1-Y)2-X (PO4)3
(Universidade Federal de São Carlos, 2018-03-22)
The primary goal of this work is to develop a new NASICON-structured glass-ceramic with high
Li-ion conductivity. Therefore, this work introduces a new series of NASICON-type compositions
based on the Li1+xCrx(GeyTi1-y)2-x(PO4)3 ...
