Written by Yong Soo Kang, Molecule and Ion Transport through Polymer Membranes, 1st Edition, offers an in-depth treatment of molecular and ionic transport phenomena across polymeric media. This book establishes a systematic framework for developing new polymeric materials based on fundamental principles such as Fick's law and solution-diffusion mechanics.
The text organizes core transport concepts into clear thematic modules. It presents free volume theory alongside diffusion and migration phenomena to describe kinetic movement. Furthermore, the volume examines facilitated transport in the solid state while providing detailed analyses of dual sorption models that govern penetrant behavior within glassy polymers during active transport processes.
By framing physical principles around practical material development, the work fills a clear instructional need for advanced research and technical implementation. It provides targeted value for polymer chemists, process engineers, membrane scientists, and chemical engineers focused on predicting and controlling penetrant flux through membrane systems.
