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
Structure and Property Relationships for Polymers
The second edition of “Professor’s Corner” included a discussion about the fundamental physical property differences between low molecular mass materials and polymers1. These included differences in flexibility, melting point and glass transition temperature (Tg), as well as the rheological properties of liquids or solutions. In this edition, we will take a closer look at … [Read more...] about Structure and Property Relationships for Polymers
The Science of UV/EB Polymerization
The first edition of this column included a brief “Introduction to Polymer Science.”1 Polymeric materials were defined as those containing molecules of very large size and molecular mass. These “macromolecules” then were classified into three different categories: linear polymers, branched polymers and crosslinked polymers. Any given sample may contain mixtures of two or more … [Read more...] about The Science of UV/EB Polymerization
