ABSTRACT Janus nanorods are used as a novel rigid compatibilizer to improve the interfacial tension of incompatible A/B homopolymer blends. Dissipative particle dynamics (DPD) methods are preformed to explore the effect of Janus nanorods on the interfacial tension. The results show that Janus nanorods are a good compatibilizer only when the appropriate length is chosen, which is different from the traditional coil compatibilizer (surfactants and block copolymers). The length of the Janus nanorods can significantly influence their orientation through the competition between the entropic and enthalpic effects. The shorter Janus nanorods preferring 'standing' have a better efficiency in improving the interfacial tension than the longer ones preferring 'lying.' If we can control the orientation of the longer Janus nanorods, they are still a good compatibilizer. This simulation work can widen the application of Janus nanoparticles. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 44098. [ABSTRACT FROM AUTHOR] |
