We are grateful to Nissan Chemical Corp. for kindly providing the HBP sample, and thank Prof. Hisao Matsuno, Prof. Daisuke Kawaguchi and Dr. Yukari Oda for their constructive discussion and suggestions. This study was partly supported by the JSPS KAKENHI Grant-in-Aid for Young Scientists (B) (No. JP15K17871). We also appreciate the support from the ImPACT program of the Council for Science, Technology and Innovation (Cabinet Office, Government of Japan), JST-Mirai Program (No. JPMJMI18A2) and Eno Kagaku-Shinko Zaidan, Japan. NR measurement was performed on BL-16 at the Materials and Life Science Facility, J-PARC, Japan, under Program Nos. 2014S08 and 2017L2500.

N2 - Adhesion of a model rubbery material, cross-linked poly(dimethylsiloxane) (PDMS), onto a solid surface was studied by sum-frequency generation spectroscopy and X-ray photoelectron spectroscopy. To do so, here, we have focused on the adhesive deposit and insoluble layer. The former and latter were defined as the residual amount on the substrate after the peeling and residual layer after washing with a good solvent, respectively. The peel strength of a PDMS sheet adhered onto a glass plate increased with the contact time. Both adhesive deposit and insoluble layer also exhibited comparable contact time dependence. Once a hyperbranched polymer (HBP), which was segregated to the adhesive interface, was incorporated into PDMS, the peel strength and adhesive deposit decreased, although the thickness of the insoluble layer remained almost unchanged. These results suggest that the formation of loosely adsorbed chains on the solid surface, which possess not only trains but also many loop portions and tail parts, plays an important role in the macroscopic adhesion behavior of the PDMS sheet and the interfacial segregation of HBP can prevent it.
