Abstract: | The fragility works as a fundamental concept characterizing glass-forming liquids, whereas its atomic structural interpretation remains a challenge. Herein, viscosity behaviors in polyethylene (PE), S, Se, and Te are examined, which consist of distorted chain molecules with varied interchain strength, in comparison with that in SiO2, a typical strong material. Among the 1D materials, S and PE appear to be fairly strong. Such results suggest that the viscosity exhibits Arrhenius-type behaviourif it is governed by single microscopic mechanisms such as Si-O bond scission or interchain slippages. In contrast, Se and Te appear fragile with non-Arrhenius variations, which could be ascribable to mixed inter- and intrachain interactions. Among these floppy materials, it is known that Se is the best glass former, the reason being discussed. |
