Surface Modification Chemistries for Particles and Interfaces
Monday, 24 July 2017

Synopsis:

The science and technology of nearly all particle-based materials, drug delivery systems, diagnostic methods, controlled release systems, composites, etc., involve on every length scale, from the molecular to the macro, surface and interfacial phenomena that can be tuned by varying the surface and interfacial energy and by varying the specific chemical interactions and chemical groups populating such surfaces and interfaces. This is particularly true in formulating multiphase fluids for coatings, and in making pigments and other particulate additives stable in coating fluids, prepolymers and resins of a particular coated layer or composite film. Being able to take a particle and make it “happy” in a dispersion environment that otherwise would be unstable and lead to coating defects and untoward dispersion destabilization is a skill that will make the student more competitive in the broad advanced materials and pharmaceutical industries. This course augments introductory organic, inorganic, and colloid chemistry courses by providing a broad range of practical applications of physical and synthetic chemistries that enable the student to achieve many different kinds of surface and interfacial modifications.

Basic physical-chemical methods, basic organic and inorganic coupling chemistries, and living polymerization methods are reviewed and applied to achieving diverse forms of surface and interfacial modification suitable for nanoparticles through high volume and high surface area planar substrates. The emphasis is on the application of various chemistries to enable highly value-added materials to be made in a chemically stable and robust manner.

The course is targeted at the advanced undergraduate and beginning graduate student level and will be useful to R&D chemists, materials scientists and engineers, and innovators in developing a toolbox of methods to use in optimizing formulations for advanced materials and applications.

This course reviews and illustrates the practical applications of physical, organic, and inorganic chemistry, as learned in undergraduate courses, and presents methods, for the constructive chemical surface modification of particulate and planar substrates used in diverse applications in the coatings, materials, and pharmaceutical industries. The course focuses on physical methods such as layer-by-layer assembly, physical adsorption, and upon diverse chemistries including thiol-driven self-assembly on particular substrates, diverse coupling chemistries, sol-gel silane-based chemistries, living polymerization methods, grafting chemistries including click chemistry, surface-initiated polymerization, encapsulation chemistries, and applications in controlled release, formulating composites, and advanced applications in diagnostics and array technologies.

A comprehensive reading list and extensive references are provided to facilitate the practical review of the topics covered as the need for detail arises in the workplace and development laboratory.
