Patent number: 8653194Abstract: Processes and compounds are described herein for single polymer composites based on a process for making the single polymer composites that includes the steps of heating a matrix material to create polymer melt, cooling the polymer melt to below its Tm to create an undercooled polymer melt, or quasi-melt, and combining the melt with an enhancing or reinforcing material to produce a single polymer composite. The process can produce materials that do not have any degradation of the polymer characteristic of the enhancing material due to melting of the polymer in the enhancing material.Type: GrantFiled: May 3, 2012Date of Patent: February 18, 2014Assignee: Georgia Tech Research CorporationInventors: Donggang Yao, Youjiang Wang, Pan Dai, Jinnan Chen
