Polymer Program Seminar


Polymer Nanocomposites: Structure, Properties and Utility


Prof. Daniel F. Schmidt

University of Massachusetts, Lowell


Friday, September 14, 2007
11:00 am , IMS Room 20



ABSTRACT

The term “nanoscience” has in recent times been used to describe a great variety of research focusing on new physical processes at nanometer length scales. As with many new fields, in addition to much excellent work there has also been substantial hype, with many wondering when and how the promise of this type of work will become reality.

For plastics engineers, this is an exceptionally exciting time; polymer nanocomposites represent really the first instance of recent research in the field of nanoscience being developed, commercialized, and produced. It is also a challenging time, in that these new materials have their own unique properties and characteristics that must be understood.

In the first half of my talk, I will present an overview of polymer nanocomposites (what they are and why we think they’re special), then focus on those systems based on organically modified layered silicates (often referred to as nanoclays). The properties, structure and behavior of these systems will be covered, with characterization techniques mentioned along the way. Finally, examples will be given of nanocomposites currently on the market, with an emphasis on how they have found utility.

In the second half of my talk, I will give a brief overview of the nanocomposite-related research being carried out in my group, then focus on one project in particular – our work with flexible PVC (FPVC) / nanoclay systems. We are developing FPVC nanocomposites using realistic formulations and equipment with the goal of realizing high performance via synergistic interactions. The first phase of the project involves transparent medical-grade FPVC and has allowed us to identify appropriate nanoclays and loading levels and to demonstrate resultant enhancements in properties. The second phase of our work builds on the first to develop new formulations for wire and cable applications.
