This research examines a novel, two-part primer system that allows almost any adhesive or coating to adhere strongly to silicone rubber. Based on cyanoacrylate, the system forms a thin coating that binds tightly to silicone and provides a porous, nanostructured surface to which adhesives and coatings can bond well. Crucial to the effectiveness of the primer layer is the solvent used in the second part of the primer system. The layer׳s polycyanoacrylate forms as a gel in the presence of that solvent and is subject to the solvent׳s chemical and physical influences. When the solvent has little affinity for the polycyanoacrylate, as well as a small surface tension, the gel is able to withstand capillary stresses exerted by the evaporating solvent and become a xerogel with extensive porosity and nanostructure.

Louis A. Bloomfield is Professor of Physics at the University of Virginia, where he has been teaching since 1985. Bloomfield grew up taking everything apart and, with the notable exception of one recalcitrant mechanical clock, he managed to get them all back together again (or at least that’s what he remembers). He also survived numerous electrical shocks and chemical accidents in his youth, not all of which were unexpected.
When he arrived at Amherst College, tinkering with things wasn’t offered as a major, so he chose the closest available option: he majored in physics. Bloomfield received his B.A. in 1979 summa cum laude and his Ph.D. in physics from Stanford University in 1983.
He was a postdoctoral fellow at AT&T Bell Laboratories until 1985, when he joined the faculty of the University of Virginia as an Assistant Professor of Physics. He has been there ever since. Bloomfield is the recipient of numerous awards for his research in atomic, condensed matter, and optical physics, including the Apker Award of the American Physical Society, a Presidential Young Investigator Award of the National Science Foundation, a Young Investigator Award of the Office of Naval Research, and an Alfred P. Sloan Fellowship, and he is a Fellow of the American Physical Society.
In 1991, Bloomfield decided to try teaching physics the way he originally learned physics: in the context of everyday things. He created a course called How Things Work and taught it to 92 students at the University of Virginia its first semester. Now he has more than 200 students. How Things Work – his text book is now on its 4th edition.
Bloomfield is the author of more than 100 publications in the fields of atomic clusters, autoionizing states, high-resolution laser spectroscopy, nonlinear optics, computer science, and general science literacy.
Bloomfield’s years of experimenting with everything he can get his hands on, and reading about those he can’t, have made him something rare in modern day science:
