Controlling wettability of the each side of the PLA fabric through orientation ...
Silva, Ruthilene Catarina Lima da; Alves Júnior, Clodomiro; Neves, Jorge Reinaldo Oliveira; Araujo, Rubens; Teixeira, Vasco M. P.This study aimed to obtain a bifunctional fabric from the point of view of hydrophilicity/hydrophobicity for biomedical applications. To achieve this, both sides of a fabric of polylactic acid (PLA) were subjected to a plasma treatment. While in a side the oxygen was introduced to the other side, simultaneously, was added methane. The plasma treatment was performed at 100 W, 1.8 mbar, during 30 minutes. By Scan...
Desgaste de polímeros estruturais de engenharia em contato de deslizamento com ...
Silva, Ruthilene Catarina Lima daCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Present work proposed to map and features the wear mechanisms of structural polymers of engineering derived of the sliding contact with a metallic cylindrical spindle submitted to eccentricity due to fluctuations in it is mass and geometric centers. For this it was projected and makes an experimental apparatus from balancing machine where the cylindri...
