Title:Melt Memory of Semi-Crystalline Polymers: How Chains Remember Their Semi-crystalline past
Introduction:
Professor Müller has published 600 scientific papers, has over 25,000 citations and an h-index 83. He is a member of National Academy of Engineering and Habitat of Venezuela and the Latin American Academy of Sciences. He has received a number of prestigious distinctions and awards, and is an Editor of the journal Polymer (Elsevier).
Abstract:
When polymer chains crystallize, they undergo a dramatic conformational transition from random coil to highly ordered chain segments packed within crystal lattice. Upon heating above the melting point, time is required for these ordered conformations to disappear fully. The melt can retain a “memory” of its previous crystalline organization. This memory can markedly enhance nucleation subsequent crystallization. The effect has important consequences for polymer processing and material properties. In this lecture factors influencing melt memory will be discussed, and how it may be harnessed to improve polymer processing.
