CONSORTIA AND RELATED PROJECTS

Service Life Prediction

Service Life Prediction of Polymer Coatings

Description:  NIST is conducting basic and applied research to investigate degradation mechanisms, improve characterization methods, and develop mathematical models of polymer coating degradation due to exposure to outdoor environments. Stochastic models, which are based in reliability theory and life-testing analysis, are included in the modeling efforts.

Polymer Surface/Interface Consortium

Description:  Researchers from two NIST laboratories are investigating the development of surface/interface regions and their effects on the performance of polymeric systems. Advanced characterization methods and models are being developed. Research Focus in PSI are:

Near-Field Scanning Optical Microscopy
  1. Scratch and Mar Resistance Characterization
  2. Surface Nanomechanical Characterization
  3. Surface/Interface Characterization

New PSI Consortium (the Phase III of PIC) started January 1, 2009, and please contact Li-piin Sung for more information. For PIC January 2008 workshop presntations - click "MORE INFO"

Measurement Science for Optical Reflectance and Scattering

Description: Collaborative research between four NIST laboratories is aimed at advancing the science of measuring optical reflectance properties and characterizing appearance properties of materials. Measurement techniques and mathematical models for quantifying light scattering from a material are being developed and used as input for computer rendering models and procedures for determining appearance characteristics. The research developments will be applicable in ecommerce and in the design, manufacture and sale of materials.
