Conformations

Connecting the Chemical Structures and Material Behaviors of Polymers

• Gebundenes Buch

Produktbeschreibung

The authors provide both the polymer/materials science student and practicing materials engineer a means of understanding the differences in behaviors/properties of materials made from chemically distinct polymers. This knowledge can assist them in designing polymers with chemical structures that lead to their desired material behaviors and properties. The reader will learn how the detailed chemical structures of polymers can be characterized, how their microstructural depenedent conformational preferences can be evaluated , and how these conformational preferences can by connected to the behaviors and properties of their materials.

Autorenporträt

Alan Tonelli, born in Chicago in 1942, received a BS in Chemical Engineering from the University of Kansas, in 1964 and a PhD in Polymer Chemistry from Stanford in 1968, where he was associated with the late "Father of Polymer Science" and Nobelist Professor Paul J. Flory. He was a member of the Polymer Chemistry Research Department at AT&T-BELL Laboratories, Murray Hill, NJ for 23 years. In 1991, he joined the Textile Engineering, Chemistry, & Science Department and the Fiber & Polymer Science Program in the College of Textiles at North Carolina State University in Raleigh, where he is currently the INVISTA Prof. of Fiber & Polymer Chemistry. Professor Tonelli's research interests include the conformations, configurations, and structures of synthetic and biological polymers, their determination by NMR, and establishing their effects on the physical properties of polymer materials. More recently, the formation, study, and use of inclusion complexes formed with polymers and small molecule guests, such as urea and cyclodextrins, to nanostructure and safely deliver biologically active molecules to polymer materials have been the focus of his research. Jialong Shen, born in Hangzhou, China, in 1987, received a PhD in Fiber and Polymer Science from North Carolina State University, North Carolina, United States, in 2017. His research interests include the molecular basis of polymer glass transitions, host-guest supramolecular chemistry, and the applications of bio-macromolecules such as carbohydrate polymers and enzymes. He is currently a postdoctoral research scholar in the Textile Engineering, Chemistry, & Science Department at North Carolina State University.
