Thermal and optical properties of novel polyurea/silica organic–inorganic hybrid materials

Autor: John G. Jones, Lirong Sun, Joseph A. Shumaker, Alexander N. Khramov, Marlene D. Houtz, Justin P. Moore

Publikováno v: Journal of Sol-Gel Science and Technology. 63:168-176

Current optical polymeric materials for advanced fiber laser development are susceptible to degradation due to the heat generated in high power usage. A suitable replacement light stripping material was explored to overcome this problem by examining

Publikováno v: Polymer. 50:1463-1469

Fluorinated sulfo-pendants poly(arylenethioethersulfone) copolymer, which contained 50 mol% sulfonate content per repeat unit (6F-SPTES-50), were synthesized by a nucleophilic polycondensation from 4,4-(hexafluoroisopropylidene)-diphenylthiol, 3,3′

Structures and properties of highly sulfonated poly(arylenethioethersulfone)s as proton exchange membranes

Autor: Zongwu Bai, Peter A. Mirau, Marlene D. Houtz, Thuy D. Dang

Publikováno v: Polymer. 48:6598-6604

A series of sulfonated poly(sulfonium cation) polymers, sulfonated poly(arylenethioethersulfone)s (SPTES)s possess up to two sulfonate groups per repeat unit, and can be easily converted into corresponding acid form of the SPTES polymer to form a tou

Novel Ternary Molecular Composites Prepared by a Sol–Gel Process and Their Conversion into Microcellular Foams

Autor: Marlene D. Houtz, Charles Y.-C. Lee, Hongliu Sun, Seng C. Tan, N. Venkatasubramanian, Fred E. Arnold, James E. Mark

Publikováno v: Journal of Macromolecular Science, Part A. 41:981-1000

A carboxylated polysulfone (C‐PSF) was reacted with 3‐(glycidoxypropyl)trimethoxysilane (GPS) in a sol–gel reaction to form hybrid networks. Specifically, GPS was grafted to the C‐PSF chains at their epoxy ends by ring‐opening reactions and

Molecular composites by incorporation of a rod-like polymer into a functionalized high-performance polymer, and their conversion into microcellular foams

Autor: C. Y-C. Lee, Fred E. Arnold, Hongliu Sun, Marlene D. Houtz, S. C. Tan, N. Venkatasubramanian, James E. Mark

Publikováno v: Colloid & Polymer Science. 282:502-510

Molecular composites were prepared from sulfonated modifications of polysulfone and polyphenylsulfone by incorporating relatively stiff polybenzimidazole (PBI) chains into them. The composites were characterized by Fourier-transform infrared (FT-IR)

Structural relaxation in a bulk metallic glass

Autor: Marlene D. Houtz, James M. O’Reilly, Vincent H. Hammond

Publikováno v: Journal of Non-Crystalline Solids. 325:179-186

Differential scanning calorimetry has been used to investigate the structural relaxation in a bulk metallic glass designated Vit 4. Results indicate that Vit 4 has a broad glass transition region with a glass transition temperature of approximately 6

Phase-separated, conducting composites from polyaniline and benzobisthiazole rigid-rod polymer

Autor: Sharon R. Simko, Loon-Seng Tan, Richard A. Vaia, Marlene D. Houtz, Max Alexander, Robert J. Spry, Barney E. Taylor, S. J. Bai

Publikováno v: Journal of Polymer Science Part B: Polymer Physics. 39:2539-2548

As an alternative method for processing polyaniline (PANI) from its conducting (protonated) state, vacuum casting of PANI from a methanesulfonic acid (MSA) solution provided films with electrical conductivity values of about 130–150 S/cm. In additi
