Abstract
A method of forming a nanovoided composite polymer includes forming a resin-containing layer over a substrate, the resin-containing layer including a polymer-forming phase and a sacrificial phase, curing the polymer-forming phase to form a polymer matrix containing the sacrificial phase, and removing the sacrificial phase selectively with respect to the polymer matrix to form a nanovoided composite polymer including the polymer matrix and nanovoids dispersed throughout the polymer matrix. The nanovoids may be randomly or regularly dispersed throughout the matrix. Various other methods, systems, apparatuses, and materials are also disclosed.
