Large scale synthesis of single-chain/colloid Janus nanoparticles with tunable composition

Abstract

A general approach is proposed to large scale synthesize tadpole-like composite Janus nanoparticles (JNPs). Within the head of a starting JNP achieved by electrostatic-mediated intramolecular crosslinking, a free radical initiator is incorporated. By polymerizing vinyl monomers within the head nanoreactor, the composition and performance of the JNPs are broadly tunable.
