제목 Nanoparticle Surfactants for Tailoring Morphology of Block Copolymer Colloids
초록 The mixing of polymers and NPs has opened pathways for engineering flexible composites that exhibit advantageous optical, electrical, magnetic and mechanical properties. The key role of our research involves the judicious selection of polymer shells to enhance the functionality of inorganic cores for their practical application, including their use as surfactants, thus creating new polymeric materials, sensors and organic electronics. Here I would like to introduce examples of polymer-coated nanoparticles (NPs). I will introduce a powerful strategy of using size and shape controlled NP surfactants to tailor both the external shape and internal nanoscale morphology of block copolymer (BCP) particles. Convex lens-like functional block copolymer particle with defect-free porous cylindrical channels was created via precise design of interfacial interactions between NP surfactants and BCPs. The segregation of NPs at the border of BCP particles generated the balanced interfacial interaction between BCPs and water, and produced novel structured polymer-based materials.
