Measurement Methods for Membranes
Saturday, June 9, 2012
8:00 AM

John Pellegrino, University of Colorado at Boulder, john.pellegrino@colorado.edu
Ruth Baltus, Clarkson University, baltus@clarkson.edu

Abstract: This workshop provides an overview of the entire field of membrane science, technology, and applications through measurements, and is therefore an excellent resource for novices with a technical background, as well as, seasoned veterans interested in broadening their scope (or having a refresher.) The workshop will provide a survey of the various physical and chemical properties of membranes (and membrane process characteristics) that are measured, and the equipment (instruments) and techniques used, along with their underlying principles. A mixture of classical, novel, and resource-intensive techniques are included.


  • Introduction to membranes: review of membrane types and structures; goals of measurements; broad perspective on trade-offs and opportunities in characterization
  • Overview of transport processes and figures-of-merit: flux, selectivity, rejection, sieving coefficient; simple geometric membrane models
  • Membrane materials and polymers; density and fractional free volume; thermal and mechanical analysis - differential scanning calorimetry, dynamic mechanical analysis, thermal relaxation, nanoindentation; dielectric relaxation
  • Metrology basics: metrology basics and uncertainty; measuring density-pyncnometry; solubility-sorption pyncnometry, gravimetric, SAW, QCM, TGA, calorimetry
  • Gas and vapor systems: measuring time lag for permeation; mass spectrometry-transient permeation
  • Liquid systems testing: calibrations; permeation; species fractionation; integrity
  • Porometry
  • Surface and chemical measurements: surface energy and charge; FTIR; surface chemical analysis - XPS, Auger, SIMS, RAMAN, NMR, MRI, MALDI-TOF
  • Visualization and scattering: SEM, TEM, optical, NSOM, CLSM, AFM; WAXD; SAXS; SANS; PALS
  • Other topics and motivations: (for example, ultrasonics, electrochemical, TIRF, etc.)

Abstract: This workshop will focus on emerging new membrane materials (polymeric and inorganic/organic hybrids). The workshop will not present state-of-the-art techniques for membrane fabrication. Recent developments will be presented and their potential for future industrial applications will be discussed. Topics include: membrane manufacturing by molecular self- assembly of block copolymers and other components, preparation of isoporous membranes, carbon nanotubes as selective membrane channels, nanostructured mixed matrix membranes for gas and liquid separation, recent developments in the field of reverse and forward osmosis membranes, _stimuli responsive membrane materials, membranes for controlled drug release, tailoring and properties of multicomponent membranes, The most important recent patents in these fields will be reviewed.

Klaus-V. Peinemann has more than 25 years academic and industrial experience in the field of membrane materials and application. He was head of the department of Membrane Development at GKSS, Germany, coordinating a number of European projects in this field. He is co-founder of GMT Membrantechnik GmbH, one the few European companies developing and producing gas separation membranes. Klaus-V. Peinemann served as President of the European Membrane Society, he organised or coorganised 15 international workshops on membrane preparation. Since many years he is honorary Professor at the Leibniz University of Hannover on membranes for medical applications and he is currently Principal Scientist at the Advanced Membranes and Porous Materials Center at KAUST, Saudi Arabia

Suzana P. Nunes is Associate Professor of Chemical Engineering at King Abdullah University of Science and Technology (KAUST). Her research group is part of the Water Desalination and Reuse Center at KAUST. She has been working on membrane science for more than 25 years, mainly in the Helmholtz Research Center in Germany, where she coordinated European and National projects in the field of Membranes for Energy (fuel cell, hydrogen and CO2 separations). Her current research topics are membrane manufacture by polymer self-assembly, membranes for nanofiltration, membrane distillation and other water applications as well as morphological characterization (For details see http//:npm.kaust.edu.sa).

Bruce Hinds is Associate Professor at the University of Kentucky. The focus of the Hind's group research program is to fabricate functional materials at the nanometer scale. Bruce Hinds is a pioneer in carbon nanotube based membranes. He will present the state-of-the art of CNT-based membrane research and he will discuss the future perspectives.
