Janus particles as immiscible polymer blend compatibilizers: a review

Janus particles (JPs) have two distinct chemical and/or physical properties in one particle. This review is concerned with JPs’ applications in immiscible polymer blends. An overview of immiscible polymer blends and strategies used to compatibilize these blends will be given. We will then briefly review synthesis techniques used to produce JPs and finally comprehensively discuss the literature on JPs used to compatibilized immiscible polymer blends. Because JPs offer significant advantages over other compatibilization techniques as described in this review, we believe that this emerging area will see significant growth in the future.
