Abstract

The mean diameter of poly[2‐(dimethylamino)ethyl methacrylate]‐block‐poly[2‐(diisopropylamino)ethyl methacrylate] (PDMA‐PDPA) diblock copolymer micelles can be easily adjusted from 27–155 nm (as measured by DLS) by either selective quaternisation of the PDMA block or by adding PDPA homopolymer prior to micellisation; these self‐assembled nanostructures can be shell crosslinked with 1,2‐bis‐(2‐iodoethoxy)ethane and subsequently used as templates for the preparation of silica‐coated nanoparticles and, ultimately, hollow silica nanoparticles.
