Incorporation of a low-molecular-weight, midblock-selective homopolymer into the microstructure of a microphase-ordered triblock copolymer results in preferential midblock swelling or a morphological transition, depending on the blend concentration and the size of the homopolymer chain relative to that of the host block. Since the blend properties are strongly dependent on the existing microstructure, morphological changes induced by variation in blend composition have attracted considerable interest. Recent efforts have sought to discern the phase stability of both copolymer-rich (concentrated) blends, in which parent homopolymer molecules are contained within their preferred microphase, and homo-polymer-rich (dilute) blends, in which the copolymer molecules micellize to reduce repulsive interactions in a parent homopolymer matrix. Since dilute blends typically consist of spherical copolymer micelles, most morphological studies have focused on concentrated copolymer/homopolymer blends in order to (i) tailor the blend microstructure, and properties, at the molecular level and (ii) examine macromolecular mixing in conformationally constrained nanoscale environments. In this work, we return to the dilute copolymer/homopolymer blend regime and examine the self-assembly of triblock copolymer molecules in the presence of low-molecular-weight parent and nonparent homopolymers and, in some cases, an oil.

Poly (styrene-b-butadiene-b-styrene) (SBS) triblock copolymer templates have been prepared by solvent-induced order-disorder phase transition method. Silver nanoclusters have been deposited onto the SBS copolymer templates by low energy clusters beam deposition (LECBD) method. The microstructures of the template and cluster deposits have been characterized by AFM with tapping-mode. It is shown that the triblock copolymers are self-assembled to form an in-plane cylinder ordered microstructure. In the case of low coverage (<50%), silver nanaoclusters deposited on the template tend to aggregate along with the pattern of the template and coalesce into larger nanoparticles. Optical absorption spectra reveal that the surface plasmon resonance (SPR) of silver nanoclusters deposited on the template occurs at 545nm, being a red shift of ~75nm compared to that silver nanoclusters deposited on the fused quartz substrate.
