Key Findings Applications of Dispersions/Nanocomp
osites

• Early applications Optical, electrical
• Later applications mechanical
• Before Nanodispersions/composites become a
  broad-based commercial reality
• Fundamental science needs to be advanced
• Much can be done pre-competitive
• Pool of Knowledge open swimming

4
Major Findings Critical RD Needs

11
Goals 1 2

• Develop a Common Language that will account for
  dimensionality
• Achieve stable, reproducible and controllable
  architectures through Thermodynamically and
  Kinetically controlled incorporation of
  nanoparticles or creation of nanophases.

12
Goal 3

• Build a knowledge base for functionalization
  including control of surface chemistry,
  interface, and particle morphology. An emphasis
  on interface characterization through modeling
  and experimental techniques

13
Goal 4

• Ability to measure, model, characterize and
  predict properties of Dispersions NC at
  multiple length scales. Correlate NP
  constituents interface/phase properties with
  macroscopic properties.

14
Goal 5

• Develop industrial scale processes for producing
  dispersions and NC that are economical with
  limited human health implications and are
  environmentally benign.
