    Since the morphology of the active layer in polymer solar cells plays a crucial role in determining the device performance, this work investigates the effect of solvent-polymer interaction on morphology in a poly-(3-hexylthiophene) /poly{2,7-(9,9-didodecyl-fluorene)-alt-5,5-[4′,7′-bis(2-thienyl)-2′,1′,3′-benzothia-diaole]} (P3HT/PF12TBT) blend system. With the incorporation of 3-HT into chlorobenzene (CB) solution, the aggregation of both donor and acceptor were inhibited and interconnected nanofibers could be formed by ordered and closed alignment of P3HT molecules in 3-HT containing films.

    A low cost optical biosensor is reported based on a U-shaped polymer optical fiber head functionalized with overlayers of designed amphiphilic block or random copolymers. The electrostatic interaction between the sensitized fiber optic head and the charged proteins allows the rapid detection of negatively charged bovine serum albumin (BSA) and its efficient discrimination over the oppositely charged lysozyme. Surface chemical functionalization of the fiber was also studied towards detection response optimization.

  3. Effect of homopolymer matrix on diblock copolymer grafted nanoparticle conformation and potential of mean force: A molecular simulation study

    Article first published online: 19 NOV 2014 | DOI: 10.1002/polb.23637

    This article presents a molecular simulation study describing the effect of homopolymer matrix chemistry on the shapes and conformations of diblock copolymer grafted particles, and the effective interactions between these grafted particles. The strength and location of attraction and repulsion in the potential of mean forces can be valuable in choosing monomer chemistries to tailor the assembly of the grafted particles in a matrix.

  4. Directed self-assembly of linear arrays of block copolymer cylinders

    Self-consistent field theory is used to study the self-assembly of diblock copolymers in elongated templates. This study is particularly relevant for contact hole multiplication where the goal is to use large prepatterns to produce arrays of cylindrical holes with a reduced diameter. The simulations indicate that templates with three DSA cylinders are more prone to defects in comparison to templates with a two cylinder ground state. The properties of the defect-free structures and the kinetics of melting of defects into perfect structures are also discussed.
