|Title:||A simple method to prepare highly ordered PS-b-P4VP block copolymer template||Authors:||Si, H.-Y.
|Issue Date:||3-Jan-2011||Citation:||Si, H.-Y., Chen, J.-S., Chow, G.-M. (2011-01-03). A simple method to prepare highly ordered PS-b-P4VP block copolymer template. Colloids and Surfaces A: Physicochemical and Engineering Aspects 373 (1-3) : 82-87. ScholarBank@NUS Repository. https://doi.org/10.1016/j.colsurfa.2010.10.034||Abstract:||A control strategy for tuning the film morphology of asymmetric polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) block copolymers (BCPs) is reported. After preparation of the film by spin-coating method, the as-cast films were annealed in different solvent vapor. It is found that chloroform is a wonderful solvent for forming PS-b-P4VP regular pattern. Otherwise, with changing the concentration of PS-b-P4VP, cylindrical or parallel nanostructures could be attained. The PS-b-P4VP films with cylindrical structure are used as template to deposit FePt nanoparticles into the pores. Nanoparticles reaching the bottom of the holes form a disordered magnetic array. © 2010 Elsevier B.V.||Source Title:||Colloids and Surfaces A: Physicochemical and Engineering Aspects||URI:||http://scholarbank.nus.edu.sg/handle/10635/64803||ISSN:||09277757||DOI:||10.1016/j.colsurfa.2010.10.034|
