Silicon and oxygen comprise 78% of the Earth’s crust, largely in the form of natural silicates.  Recent advances in a wide-range of applications have been developed where silicon-based polymers and composites play a vital role.  However, only a few silicon-containing polymers and fillers continue to receive much of the attention of the polymer community.  In recent years, several new materials have emerged, which can be used as additives to improve thermal, mechanical, and surface properties of various polymer systems.  Other silicon-related advances have been made in areas including, but not limited to, additive manufacturing, photo-responsive materials, semiconductors, electronics, optoelectronics, anti-icing, anti-fouling, oxidation-resistance, biosilification, and biomedical applications.  Because of the very broad scope of research in the field of polymer chemistry today, many of the topics above cannot be covered in general polymer chemistry symposia, and a silicon-focused polymer symposium is a better way to highlight them. The purpose of this workshop is to bring together a broad range of stakeholders in the area of silicon polymer chemistry. We will give special attention to attracting researchers in the area of additive manufacturing (3D printing) since this is one of the research areas growing the fastest. Additionally, a half day of the workshop will be dedicated to teaching silicon-related polymerization and/or characterization techniques in addition to the usual presented research talks.
