A new synthetic route to prepare II–VI nanoscale materials, such as CdS nanorods and ZnSe nanoparticles is demonstrated and the advantage of using nonionic triblock copolymer systems,i.e., H (– OCH 2 CH 2)x[– OCH ( CH 3)– CH 2]y(– OCH 2 CH 2)y– OH , or ( EO )x( PO )y( EO )x as structure-directing agents in the synthesis of low dimension nanomaterials is introduced. The effect of (EO)/(PO) ratio in controlling the diameter and the morphology of the final product is addressed. The employ of F127 [( EO )106( PO )70( EO )106] as a surfactant-template to study the temperature-dependent size-selection of ZnSe nanoparticles is also presented. We observe that the larger ZnSe nanoparticles are arrested first by the hydrophilic fractions of triblock copolymers F127, while the smaller particles still remain their thermal motion in the aqueous phase.

We investigated the interfacial properties of symmetric ternary An/AmBm/Bn and An/Am/2BmAm/2/Bn polymeric blends by means of dissipative particle dynamics (DPD) simulations. We systematically analyzed the effects of composition, chain length, and concentration of the copolymers on the interfacial tensions, interfacial widths, and the structures of each polymer component in the blends. Our simulations show that: (i) the efficiency of the copolymers in reducing the interfacial tension is highly dependent on their compositions. The triblock copolymers are more effective in reducing the interfacial tension compared to that of the diblock copolymers at the same chain length and concentration; (ii) the interfacial tension of the blends increases with increases in the triblock copolymer chain length, which indicates that the triblock copolymers with a shorter chain length exhibit a better performance as the compatibilizers compared to that of their counterparts with longer chain lengths; and (iii) elevating the triblock copolymer concentration can promote copolymer enrichment at the center of the interface, which enlarges the width of the phase interfaces and reduces the interfacial tension. These findings illustrate the correlations between the efficiency of copolymer compatibilizers and their detailed molecular parameters.
