粉体状粘着剤の開発：合成および構造・物性評価

抄録

Pressure-sensitive adhesive (PSA) powder consists of millimeter-sized particles with a soft sticky polymer core and a hard solid nanoparticle shell morphology (adhesive liquid marbles), and shows no adhesion in its original form and flows like a powder through a funnel. Only after application of external mechanical stress, it acts as an adhesive. Adhesion can be induced by rupture of the nanoparticle coating of the liquid marble and outflow of the inner soft polymer. This article gives an exposition of fabrication and characterization of surface structure/chemistry, morphology and adhesive properties of PSA powder and adhesive liquid marble.
