DOI: 10.1063/1.4980053
Abstract: The adhesion behavior of elastomeric nanofibers was examined by a contact-mechanical approach using a Johnson–Kendall–Roberts (JKR) instrument. A nanofibrillar elastomer substrate was fabricated by replicating crosslinked polydimethylsiloxane (PDMS) from an anodic aluminum oxide (AAO) template.… read more here.
