Plasma Techniques for Preparation of Controlled Drug Release System
Springer Science and Business Media LLC - Tập 6 - Trang 145-162 - 2001
Masayuki Kuzuya, Shin-ichi Kondo, Yasushi Sasai
Plasma-induced surface radicals formed on a variety of organic polymers have been studied by electron spin resonance (ESR), making it possible to provide a sound basis for future experimental design of polymer surface processing, i.e., plasma treatment. On the basis of the findings from such studies, several pharmaceutical applications in the field of drug engineering have been devised, which incl...... hiện toàn bộ
Behavior of Plasma-Treated Elastomeric Polydimethylsiloxane Coatings in Aqueous Environment
Springer Science and Business Media LLC - Tập 3 - Trang 23-34 - 1998
Gregory G. Bausch, Jennifer L. Stasser, James S. Tonge, Michael J. Owen
Plasma treatment is a useful way of enhancing the wettability of polydimethylsiloxane (PDMS). The subsequent recovery of hydrophobicity in air once treatment is discontinued is well known, but less has been reported about the effect of the storage environment. Water storage is the most relevant, with some reports that this stops the hydrophobic recovery of plasma-treated Medical Grade PDMS elastom...... hiện toàn bộ
Plasma-Induced Graft Polymerization of Poly(ethylene glycol) Methyl Ether Methacrylate on Si(100) Surfaces for Reduction in Protein Adsorption and Platelet Adhesion
Springer Science and Business Media LLC - Tập 7 - Trang 151-170 - 2002
X. P. Zou, E. T. Kang, K. G. Neoh
Argon plasma-induced graft polymerization of a solution-coated macromonomer, poly(ethylene glycol) methyl ether methacrylate (PEGMA), on the Si(100) surface was carried out to impart anti-fouling properties to the Si(100) surface. The surface composition and microstructure of the PEGMA graft-polymerized Si(100) surfaces were characterized by X-ray photoelectron spectroscopy (XPS), Fourier-transfor...... hiện toàn bộ

Comparison of Films Deposited from Pulsed and Continuous Wave Acetonitrile and Acrylonitrile Plasmas
Springer Science and Business Media LLC - - 1998
Aaron E. Lefohn, Neil M. Mackie, Ellen R. Fisher
Continuous wave (CW) and pulsed acetonitrile and acrylonitrile plasmas have been used to deposit thin nitrogen-containing films. Changes in film composition with applied CW power and pulse duty cycle have been monitored using Fourier transform infrared spectroscopy (FTIR) and deposition rates have been measured for both systems. A detailed description of FTIR peak assignments is presented and show...... hiện toàn bộ
Identification of Fragment Ions by Their Kinetic Energy Gained During Dissociative Ionization by Electron Impact
Springer Science and Business Media LLC - Tập 4 - Trang 259-268 - 1999
R. Foest, R. Basner, M. Schmidt
A technique is described, which supports the plasma mass spectrometry to distinguish possible sources of ion peaks found in the mass spectrum of the neutral gas. The proposed method is based on the measurement of the kinetic energy which the fragment ions gain during dissociative ionization by electron impact inside the ion source of the spectrometer. This approach is of special interest for appli...... hiện toàn bộ
Effects of Cathode and Anode on Deposition of Trimethylsilane in Glow Discharge
Springer Science and Business Media LLC - Tập 7 - Trang 41-55 - 2002
Q. S. Yu, H. K. Yasuda
DC cathodic polymerization of trimethylsilane (TMS) was carried out in plasma reactors with and without using anode assembly. In DC cathodic polymerization, the TMS plasma polymers are mainly deposited on the cathode (substrate) surface. As a result, fast deposition of TMS plasma polymers was easily achieved in DC cathodic polymerization as compared with AF or RF plasma polymerization. DC cathodic...... hiện toàn bộ
Plasma-Deposition of Ag-Containing Polyethyleneoxide-Like Coatings
Springer Science and Business Media LLC - Tập 5 - Trang 1-14 - 2000
Pietro Favia, Michele Vulpio, Rosamaria Marino, Riccardo d'Agostino, Rogerio Pinto Mota, Massimo Catalano
Ag-containing polyethyleneoxide (PEO)-like thin films have been deposited in Radio Frequency Glow Discharges fed with vapors of diethyleneglycol-dimethylether and argon. Proper experimental conditions have been utilized in order to fragment the monomer in the glow and, at the same time, sputter Ag from the silver RF cathode of the reactor, in a way that polyethyleneoxide(PEO)-like coatings with em...... hiện toàn bộ
Vacuum Ultraviolet Irradiation of Polymers
Springer Science and Business Media LLC - Tập 4 - Trang 183-206 - 1999
A. C. Fozza, J. E. Klemberg-Sapieha, Michael R. Wertheimer
The interest in incoherent sources for wavelength-selective photochemistry has increased lately, but little is still known about the behavior of polymers when exposed to far UV and vacuum UV (VUV) radiation. The same dearth of information exists regarding UV (VUV) radiation emitted by low-pressure plasmas during polymer treatment. In order to study VUV-UV effects on several polymers (polyethylene ...... hiện toàn bộ
