Cyclopentanol

Surface energies of the nonwoven samples were evaluated using the Owens, Wendt, Rabel and Kaelble method [26 (link)]. Wetted length was calculated using n-hexane (Sigma Aldrich, Gillingham, UK), and contact angle values with ethanol, 1-octanol, cyclopentanol (all Sigma Aldrich) and distilled water. Experiments were performed using a KRÜSS K100 tensiometer (KRÜSS GmbH, Hamburg, Germany).
