Modeling predicts unique mechanical properties in polyphenylacetylene networks, indicating potential applications in materials science.
A series of polyphenylacetylene networks are modelled through force-field based simulations and are predicted to exhibit unusual mechanical properties, namely, negative Poisson’s ratios (auxetic), a property which is explained through a simple model involving a network of connected rotating triangles.
