Combinatorial Methods for Investigations in Polymer Materials Science

April 1, 2002
Author(s)
J C. Meredith, A P. Smith, A J. Crosby, Eric J. Amis, Alamgir Karim
Combinatorial methods of drug discovery in pharmaceuticals research are well known and more recent applications have led to the discovery and synthesis of new inorganic materials, catalysts, and organic polymers. Polymeric coatings play an important role

Organization of Hybrid Dendrimer-Inorganic Nanoparticles on Amphiphilic Surfaces

January 1, 2002
Author(s)
Franziska Grohn, X H. Gu, H Grull, J C. Meredith, G Nisato, Barry J. Bauer, Alamgir Karim, Eric J. Amis
Nanosize dendrimer-inorganic hybrid particles have been selectively deposited on micron- scale hydrophilic domains of amphiphilic surfaces, both on SAMs of alternating stripes of acid- and methyl- terminated thiols and on the amphiphilic phase of a PDLA

Phase Diagram of a Nearly Isorefractive Polyolefin Blend

January 1, 2002
Author(s)
Haonan Wang, Charles C. Han, K Shimizu, Erik K. Hobbie, Z G. Wang, J C. Meredith, Alamgir Karim, Eric J. Amis, B S. Hsiao, E T. Hsieh
The phase diagram of coexisting liquid-liquid phase separation (LLPS) and crystallization in nearly isorefractive blends of statistical ethylene/hexane and ethylene/butene copolymers has been investigated. A variety of techniques that exploit

2 Combinatorial Methods Polymer Science: Synthesis and Characterization

November 1, 2001
Author(s)
J C. Meredith, A P. Smith, Alamgir Karim, Eric J. Amis
Combinatorial methodologies offer the ability to efficiently measure relevant chemical and physical properties over lare regimes of varible space. We review recent work in the development of combinatorial methods for polymer synthesis and characterization

Studies of polymer-filler interactions in filled systems

August 1, 2001
Author(s)
Alamgir Karim, Jack F. Douglas, K A. Barnes, A Nakatani, D W. Liu, Eric J. Amis
We observe that the presence of filler partiocles can have a major impact on the properties of filled polymer blend materials. The filler particles, which are found in many commercial polymer blends, modify the phase boundary (interfacial tension, rate of

Combinatoral Study of Surface Pattern Formation in Thin Block Copolymer Films

July 1, 2001
Author(s)
A P. Smith, Jack F. Douglas, Alamgir Karim, J C. Meredith, Eric J. Amis
We investigate surface patterns in thin block copolymer films with a gradient in thickness, h. The usual hole and island morphologies are found when h varies from integral multiples m of the bulk lamellar thickness Lo but spinodal-like hole and island
