| Abstract: | Auxetics exhibit the anomalous property of getting wider rather than thinner when uniaxially stretched, i.e. have a negative Poisson's ratio. This work presents the results of simulations performed on a number of hypothetical poly(phenylacetylene) networks which are meant to mimic the behaviour of rotating scalene triangles. It was shown that such systems do indeed exhibit a negative Poisson's ratio being as low as c. −1.2, i.e. lower than the c. −1 found in earlier systems. This negative Poisson's ratio is due to the relative rotation of nanoscopic units. |
