Regeneration and Remodeling of Composite Materials.

摘要

The Regeneration and Remodeling of CompositeMaterials (Regeneration) Program was supported by the Air Force Office of Scientific Research (AFOSR) through a Discovery Grant from 2010-2015. The program was conducted at the University of Illinois at Urbana-Champaign (UIUC). Regeneration was conceived to expand the function of materials containing microvascular networks to achieve autonomous response and adaptation to external stimuli. The central goal of Regeneration was to integrate bio-mimetic functions into synthetic, engineering materials realized through a synergistic combination of expertise in chemistry and engineering. The Regeneration and Remodeling of Composite Materials program was focused on replicating the function of regeneration in which natural systems rebuild or replace macroscopic structures autonomously. Inspired by this biological ability, vascular networks were designed to synthetically regrow load-bearing structures and replenishing protective surface coatings.Multistage polymerization reactions introduced a new paradigm in healing agent conceptual design where rapid rheological transformations and selective wetting resulted in new self-supporting fluids which build upon themselves in an accretive
