A novel thermoforming processing route has been developed that produces a microporous form of ultra high molecular weight polyethylene that demonstrates large negative Poisson's ratios. The microstructure consists of nodules interconnected by fibrils. Poisson's ratios as low as - 1.2 have been obtained, depending on the degree of anisotropy in the material.
