Abstract:
We will discuss a current project whose aims are to develop new technology to control the ultimate properties of bulk materials through controlling the morphology (or self assembly) of existing, low cost materials. Areas of interest for materials with well defined 3D period morphologies include photonic materials and nanocomposites with superior thermomechanical properties. Initial results using Dissipative Particle Dynamics (DPD) studies of grafted ìcombî, ìstarî, and dendritic copolymer structures indicate that large variations to a materialís morphological phase diagram can be effected by modifying the supra-molecular architecture of the material. This study is the first in a series that will be used to predict bulk properties of bulk systems, blends and composites using multi-scale modeling approaches.
