System to measure torsion modulus of polymers using the deformation energy method
(Assoc Brasil Polimeros, 2019-01-01)
This paper presents an alternative method to measure the torsion modulus, G, for samples of polymers. We constructed a measurement system with a force sensor (FS) and a rotational movement sensor (RMS) to obtain a relationship ...
Enhancement of polymer hydrophobicity by SF6 plasma treatment and argon plasma immersion ion implantation
(2003-02-01)
In this study sulphur hexafluoride (SF6) plasmas and argon plasma immersion ion implantation (ArPIII) techniques have been applied to improve the hydrophobicity of poly(tetrafluoroethylene) (PTFE), polyurethane and silicone ...
