✦ Synopsis

Abstract

We report a novel rubber film made by a simple mixing method, which realizes a steep temperature dependence of the contact angle of water at a critical temperature of 41 °C. We mixed a common SBR with a known temperature‐responsive PNIPA to make a thermo‐responsive rubber. This rubber film distinctly showed a switch of surface wettability between hydrophilic below 41 °C and hydrophobic above 41 °C. The switching property is possibly controlled by the mixing ratio of PNIPA to SBR, preparation method, added chemicals, and so on. This mixing technique will be applied for the control of surface wetting properties by temperature on various SBR‐like rubber materials, such as wet‐brake performance of automobile tires on a rainy day.

## Abstract We describe the thermal‐driven evolution of stripe domain structures in ultrathin magnetic films with perpendicular anisotropy. Taking into account temperature dependencies of the film magnetic parameters we analyze possible temperature dependencies of the domain period. It is shown tha

Wettability of sol-gel TiO 2 film surfaces has been studied by following the H 2 O contact angle (θ) as functions of illumination time and subsequent dark storage time. Upon illumination of the TiO 2 surface (λ ex > 300 nm), the value of θ rapidly decreased to reach approximately zero (photoprocess)
