| その他のタイトル | “Warm-Off” Mechanism of Acrylic Pressure Sensitive Adhesive Containing Side-Chain Crystalline Polymer by Use of Atomic Force Microscope | |||||||||||

| 内容記述タイプ | Abstract | |||||||||||
| 内容記述 | A pressure sensitive adhesive (PSA) is one that adheres instantly to an adherend through the application of light pressure, and detaches easily and without residue by pulling lightly. A PSA losing its adhesion rapidly above a certain temperature is called “warm-off” (WO) type one. A PSA containing a copolymer with a long alkyl chain as its crystalline component is one of the WO type ones. The WO mechanism is, however, not yet well-understood. Our aim is to propose the WO mechanism demonstrated experimentally. To establish the WO mechanism, PSAs consisting of a base resin and the crystalline copolymer were examined for their surface morphologies by tapping-mode atomic force microscopy. As the results, we propose a possible mechanism as follows: (i) sphere particles assignable to the crystalline component are dispersed on the surface of the base resin; (ii) the particles are covered by the base resin as the PAS adheres to an adherend through the application of light pressure; (iii) after heating above the fusion temperature of the crystalline component, the melted crystalline component comes out to the interface between the PSA and adherend, which leads to losing its adhesion. |
