Coalesced polymers are obtained via nano-confinement of guest polymers in cyclodextrin or urea host molecules and their subsequent release. Our research indicates improved mechanical properties, higher non-crystalline densities, higher glass transition temperatures, higher crystallization temperatures, and higher degree of crystallinities for such coalesced samples, and are stable to melt annealing for long periods. These results suggest that we can use coalesced polymers as nucleating agents. Restructuring polymers in this fashion allow us employ coalesced polymer in self-reinforced composites. Self-reinforced composites consist of chemically identical matrix and reinforcement components. Tailored microstructures of reinforced component provides required strength to the composite. Coalesced polymers are suitable candidates for reinforcing their as-received matrixes due to their distinct microstructures and physical properties.
