Superhydrophobic electrosprayed PTFE
(2007-11-15)
This paper shows the deposition of superhydrophobic PTFE (polytetrafluoroethylene) films on FTO (fluorine doped tin oxide) coated glass slides, employing the electrospray technique, using a commercial PTFE particle suspension ...
Calcium sulfate and PTFE nonporous barrier for regeneration of experimental bone defects
(Medicina Oral S L, 2008-06-01)
The aim of the study was to evaluate the possibility to obtain guided bone regeneration with two types of physical barriers (calcium sulfate and PTFE nonporous barrier) in surgical defects created in rat parietal bones. ...
Nanotexturized polytetrafluoroethylene substrates formed by large crystalline nanofibrils in amorphous matrices
(Amer Scientific PublishersStevenson RanchEUA, 2008)
Comparison of the inflammatory reaction induced by facial implants os silicone and polytetrafluoroethylene. Study in rabbitsComparación de la reacción inflamatoria inducida por implantes faciales de silicona y politetrafluoroetileno. Estudio en conejos
(2019-01-01)
Background and Objective. The treatment for many facial deformities uses many kinds of autologous grafts or alloplastic materials. Polytetrafluoroethylene (PTFE) has several advantages due to its hydrophobic properties, ...
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 ...
Alternative dynamic torsion test to evaluate the elastic modulus of polymers
(Iop Publishing Ltd, 2020-09-01)
This work presents an alternative for the determination of the torsion modulus, G, of polymers. These materials may be subjected to shear stresses in some structural applications; thereby, the knowledge of G is of great ...
Synergistic contribution on flame retardancy by charring production in high-performance PEI/PBT/PTFE ternary blends: The role of PTFE
(Wiley, 2021)
High-performance binary blends between poly(ether imide) (PEI) and flame-retardant poly(butylene terephthalate) (PBT) are modified with 5, 10, and 15 wt% of poly(tetrafluoroethylene) (PTFE) using a two-step melt-processing ...
Polyurethane and PTFE membranes for guided bone regeneration: Histopathological and ultrastructural evaluation
(Medicina Oral S L, 2010-03-01)
Objective: The purpose of this study was to research a membrane material for use in guided bone regeneration. Study design: In this study, 25 male Wistar rats were used to analyze the biocompatibility and degradation process ...
