Optical coatings and films are the foundation of many 3M products ranging from traffic signage and high visibility safety garments to films that enhance features such as brightness of LCD and OLED displays. These highly engineered coatings and films modulate the transmission, reflection, and/or absorption of light in unique ways. This talk will dive into the polymer and nanoparticle materials used in water-borne optical coatings with specific focus on a specialty coating method called layer-by-layer (LbL) assembly. LbL coating is a multi-step process that deposits oppositely charged materials with highly controlled nanoscale thickness. This talk will include a description of this technology along with four application vignettes. In addition, an overview of 3M Company and the 3M Corporate Research Lab will be provided to give perspective on industrial R&D.
