Preparation and Physical Characterization of Sulfonated Poly (Ether Ether Ketone) and Polypyrrole Composite Membrane
Sulfoanted poly(ether ether ketone) membranes were prepared by the sulfonating agent sulfuric acid. These membranes were modifed by incorporating conducting polymer polypyrrole in order to increase the ionic conductivity and reduce the methanol transmission rate. The modifed composite membranes were then compared on the basis of ionic conductivity, methanol transmission...
متن کاملExpandable Polyaryl-Ether-Ether-Ketone Spacers for Interbody Distraction in the Lumbar Spine
Study Design Retrospective case series. Objective StaXx XD (Spine Wave, Inc., Shelton, CT, United States) is an expandable polyaryl-ether-ether-ketone (PEEK) wafer implant utilized in the treatment of lumbar degenerative disease. PEEK implants have been successfully used as interbody devices. Few studies have focused on expandable PEEK devices. The aim of the current study is to determine the r...
متن کاملComparison of osteogenic potential of poly-ether-ether-ketone with titanium-coated poly-ether-ether-ketone and titanium-blended poly-ether-ether-ketone: An in vitro study
STATEMENT OF PROBLEM Poly-ether-ether-ketone (PEEK), a high-performance semi-crystalline thermoplastic polymer, has been employed to replace the metallic implant components in orthopedics. There were various studies performed in accordance to medical grade PEEK, but the relationship between titanium dioxide (TiO2)-coated PEEK, TiO2-blended PEEK, and untreated PEEK still remains complicated, eve...
متن کاملThe Effects of Sulfonated Poly(ether ether ketone) Ion Exchange Preparation Conditions on Membrane Properties
A low cost cation exchange membrane to be used in a specific bioelectrochemical system has been developed using poly(ether ether ketone) (PEEK). This material is presented as an alternative to current commercial ion exchange membranes that have been primarily designed for fuel cell applications. To increase the hydrophilicity and ion transport of the PEEK material, charged groups are introduced...
متن کاملA Novel Polyaryl Ether Based Photorefractive Composite
We report the synthesis of a novel charge-transporting polymer based on the chargetransport unit N,N′-diphenyl-N,N′-bis(3-methylphenyl)-[1,1′-biphenyl]-4,4′-diamine (TPD). Introducing approximately 30 wt % of the liquid electro-optic molecule 4-(N,N-diethylamino)2-fluoro-(Z)-â-methyl-(E)-â-nitrostyrene (FDEAMNST) and small amounts of C60 makes this polymer photorefractive. A full photorefractiv...
