Article
Amphiphilic Polymer Conetworks Based on End-Linked "core-First" Star Block Copolymers: Structure Formation with Long-Range Order
(2015)Amphiphilic polymer conetworks are cross-linked polymers that swell both in water and in organic solvents and can phase separate on the nanoscale in the bulk or in selective solvents. To date, however, this phase separation ...
