About Lucia Fernandez-Ballester

My research goal is to achieve optimal and detailed control of the morphology and properties of semicrystalline polymers so that growing technological needs can be addressed.  In order to enable rational design of materials and processes, I seek a fundamental understanding of the relationship between polymer molecular structure, processing conditions, morphology and final properties.  I place particular emphasis in revealing the impact of small changes in polymer molecular architecture and chemical makeup, and in exploring how the pathway of structure formation can be selected by using appropriate processing conditions.  Ultimately, manipulation and fine control of polymer morphology and properties can lead to advanced and complex materials.

A range of in-situ and ex-situ experimental techniques is needed to explore molecular characteristics, structure development, and final morphology. Some of the experimental techniques used are differential scanning calorimetry (DSC), polarized optical microscopy (POM), real-time optical birefringence, and synchrotron X-ray scattering (WAXD/SAXS).
