Research by Case School of Engineering professors, VA collaborators earn cover of prestigious science publication

Cleveland, OH | Posted on January 5th, 2008

An interdisciplinary team from the department of macromolecular science and engineering at Case Western Reserve University, the Louis Stokes Cleveland VA Medical Center and the NASA Glenn Research Center earned the December 2007 cover of Nature Nanotechnology, one of the world's most prestigious scholarly journals covering research in nanoscience and nanotechnology.

Jeffrey R. Capadona, associate investigator at the VA's Advanced Platform Technology (APT) Center and Christoph Weder and Stuart Rowan, professors of macromolecular science and engineering at the Case School of Engineering and their colleagues have unveiled a method for developing mechanically-reinforced polymer nanocomposites.

The incorporation of nanoparticles into polymers is a design approach that is used in all areas of materials science, says Weder, who is the senior author of the paper, adding that in the past, the broad technological utilization of polymer nanocomposites has been stifled by a lack of effective methods to control nanoparticle dispersion in materials.

In their new approach, the team used a process in which the reinforcing nanoparticles are first assembled into a three-dimensional network through gelation of nanoparticle dispersion, essentially forming a template. This template can then be filled with any polymer of choice by exchanging the solvent with a polymer-containing solution.

"Through the use of this new technique, we have been able to take the most incompatible components and show that they can be used to make compatible materials," Weder said.

While the research primarily focused on cellulose "whiskers" as the choice of nanoparticles since they offer useful mechanical properties and are readily obtained from renewable biosources such as wood and cotton, Capadona explained, the team also started to investigate an array of different polymers and nanofibers, demonstrating that the technique has broad applicability.

In addition to Weder, Capadona and Rowan, other members of the research team include Dustin J. Tyler, the Nord Distinguished Assistant Professor of Biomedical Engineering at Case Western Reserve and APT associate director; Otto van den Berg and Michael Schroeter, both former postdoctoral researchers in Weder's Functional Polymer Laboratory; and Lynn A. Capadona of the polymeric materials branch, NASA Glenn Research Center. While the work was primarily conducted in the Case School of Engineering's department of macromolecular science and engineering, the Department of Veterans Affairs and the VA Rehabilitation R&D Center of Excellence in Advanced Platform Technology (APT) contributed financially and played an important role in this research uniting Weder, Capadona, Tyler and Rowan to conduct research in the area of adaptive nanocomposite materials, which are now fabricated by the new process.

Case Western Reserve University has filed for a patent protecting the technology.

The APT center is a cohesive intellectual community that offers its investigators the opportunity to meet regularly, have discussions within and outside of their fields, participate in electronic mailing lists, and attend educational and scientific conferences. It allows access to state-of-the-art facilities including MEMS design and fabrication, mixed signal and wireless communication laboratories, telemetry laboratories, support staff and other technical and clinical resources.

Nature Nanotechnology is a multidisciplinary journal that publishes papers of the highest quality and significance in all areas of nanoscience and nanotechnology. The journal covers research into the design, characterization and production of structures, devices and systems that involve the manipulation and control of materials and phenomena at atomic, molecular and macromolecular scales.
