Abstract

Employing amphiphilic block copolymers in a casting process to obtain honeycomb-structured films via breath figures leads to a suborder of these porous films. A thermoresponsive block cop olymer, polystyee- block-poly(N-isopropyl acrylamide), was synthesized and used to test the arrangement of both blocks within the honeycomb-structured films. Contact angle measurements reveal that the surface of these films has a different composition compared to the structure of the pores. The pores were found to be enriched in hydrophilic sequences showing stimuli-responsive behavior, whereas the surface reacts like a typical hydrophobic porous film. © CSIRO 2005.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
