Poly(methyl methacrylate) films were prepared by annealing below their glass-transition temperatures after spin-casting and were symmetrically pressed against each other with constant pressure in air. The films successfully adhered together with only water droplets. The interfacial adhesion strength was quantitatively examined by lap-shear tests. Polymer chains swollen with water molecules caused significant entanglement and resulted in strong adhesions.
