Optimizing Glassy Polymer Network Morphology for Nano-Particle Dispersion, Stabilization and Performance
Abstract
MWCNT nanocomposite aerospace prepolymers were successfully prepared in a one-step high volume process through the development of a new preparation approach based upon a high-shear continuous reaction method. The continuous reactor based upon two principle advancements in process engineering. 1. Chain extension prepolymer reactions including curative dissolution, toughener dissolution and controlled chain-extension reactions in the continuous reactor high temperature hot-zone to advance conversion, rheology and tack. 2. Simultaneous MWCNT dispersion and stabilization in the continuous reactor low temperature cold-zone leading to an increased viscosity and stabilization of MWCNTs within rheological regimes which inhibit re-agglomeration to aid in post processing stabilization of dispersion state through final cure.
