In this edition of “Professor’s Corner,” a discussion of Intermolecular Attractive Forces is continued. In Part 11, the subject was introduced, and London Dispersion Forces (LDFs) were discussed. These are the forces of attraction exhibited by all atomic, ionic or molecular materials, even those that are completely non-polar. In this edition, we will look at the attractive … [Read more...] about Intermolecular Attractive Forces: The Key to Understanding Polymer Properties, Part 2

Intermolecular Attractive Forces: The Key to Understanding Polymer Properties, Part 1
To understand the nature of solids and liquids, the forces of attraction holding the component atoms, molecules and/or ions together must be considered. Without these forces, only gases would be possible, and the universe would be a very different place. So, for solids and liquids to exist at all, gaseous species must have the inherent ability to attract one another strongly … [Read more...] about Intermolecular Attractive Forces: The Key to Understanding Polymer Properties, Part 1

Changing Polymer Properties through Manipulation
In the first three editions of this column, the groundwork for better understanding the nature of polymers – vis-à-vis lower molecular mass materials – was laid. In this edition, we will look at factors that chemists, chemical engineers and materials scientists can, in principle, manipulate to change polymer properties. These include changes that can be made in composition, … [Read more...] about Changing Polymer Properties through Manipulation
RadLaunch Serves as Connector for Sulfluor Research
By Nancy Cates, contributing editor, UV+EB Technology Sulfluor, a fluorinated hypervalent sulfur-containing polymer, may have the potential of competing with other hard, thin films, such as plasma-deposited silicones or Kevlar. Hard, photochemically cured coatings may find applications in 3D printing, protection of sensor windows, optical fibers, electronic devices and other … [Read more...] about RadLaunch Serves as Connector for Sulfluor Research
