Examples of network polymers
WebA polymer network is like a three-dimensional net made out of long, molecular string. In MONET, we refer to the pieces of “string” as strands that are tied together at junctions (the “knots” in the netting, above). We are designing and synthesizing new strands and junctions that have remarkable properties, and learning how to optimize ... http://www.cof.orst.edu/cof/wse/faculty/Nairn/Characterization.pdf?q=faculty/Nairn/Characterization.pdf
