poly n-isopropylacrylamide was successfully grafted onto a polystyrene cell culture dish by gamma ray. in this study, the effect of a radiation dose (radiation absorbed dosages of 10, 20, 30, 40 kgy) under appropriate temperature and grafting conditions was investigated. the ftir analysis showed the existence of the graft pnipaam on the substrate. the optimal value of the dose for grafting was ...

Macromolecules with cyclic topologies have attracted significant attention because of their unique structures.

Mechanofluorescent polymer probes were used to visualize stresses and bond scission in polystyrene polycarbonate. Sonication of with a molar mass 1.1 × 105 g·mol–1 solution resulted 30% activation after 1 h, while shorter showed lower percentages. Single-asperity sliding friction tests performed on mechanophore-containing polycarbonate films. Polystyrene clearly visible crack formation correlat...
