Graftização de polipropileno-G-anidrido maleico sobre microesferas ocas de vidro por extrusão reativa
(Universidade Federal de São Carlos, 2018-08-24)
Using a maleic grafted polypropylene copolymer as a compatibilizing agent on a composite with hollow glass microspheres HGM is one way to reduce the mechanical properties decrement associated to the round, hollow, hydrophilic ...
Modificação química de poli(ácido láctico) com monômeros vinílicos, por processamento reativo, visando ajuste molecular e sua utilização em blendas poliméricas
(Universidade Federal de São Carlos, 2018-09-24)
Poly(lactic acid) (PLA) was modified with maleic anhydride (MA) or glycidyl methacrylate (GMA) in the presence of peroxide to assess the physical and chemical changes of the polymer during the reactive processing. Chemical ...
Síntese e sinterização em micro-ondas, e caracterização da Perovskita BA 0,5Sr0,5Co0,8Fe0,2O 3-δ
(Universidade Federal de São Carlos, 2014-02-27)
Ba0,5Sr0,5Co0,8Fe0,2O3-δ (BSCF) perovskite-type oxide is currently one of the most promising materials for applications in oxygen separation membranes. BSCF powder synthesis has received considerable attention because ...
Resídulo de bauxita: mapeamento da produção científica e tecnológica de sua aplicação em materiais cimentícios
(Universidade Federal de São Carlos, 2018-07-31)
Bauxite residue (BR) is the major waste generated during alumina extraction from bauxite. The global average for the production of BR is estimated between 1 and 1.5 ton per ton of alumina. The most important process worldwide ...
Correlação entre morfologia, percolação elétrica e propriedades mecânicas de compósitos da blenda PLA/PBS com grafite expandido
(Universidade Federal de São Carlos, 2013-12-06)
