Interaction between a Side Chain Crystalline Block Copolymer and Wax

Controlling the morphology of side chain liquid crystalline block copolymer thin films through variations in liquid crystalline content.

In this paper, we describe methods for manipulating the morphology of side-chain liquid crystalline block copolymers through variations in the liquid crystalline content. By systematically controlling the covalent attachment of side chain liquid crystals to a block copolymer (BCP) backbone, the morphology of both the liquid crystalline (LC) mesophase and the phase-segregated BCP microstructures...

Surface Induced Tilt Propagation in Thin Films of Semifluorinated Liquid Crystalline Side Chain Block Copolymers

The supramolecular self-assembly within a liquid crystalline block copolymer thin film with mesogenic semifluorinated alkyl side groups was studied using both grazing incidence X-ray diffraction and small angle scattering. Previous studies employing near-edge X-ray absorption fine structure spectroscopy indicated that mesogens at the film surface are tilted relative to the surface-normal. This ...

Effective interaction between monolayers of block copolymer compatiblizer in a polymer blend

Magnetic Alignment of Block Copolymer Microdomains by Intrinsic Chain Anisotropy.

We examine the role of intrinsic chain susceptibility anisotropy in magnetic field directed self-assembly of a block copolymer using in situ x-ray scattering. Alignment of a lamellar mesophase is observed on cooling across the disorder-order transition with the resulting orientational order inversely proportional to the cooling rate. We discuss the origin of the susceptibility anisotropy, Δχ, t...

Mechanical Behavior of Side-Chain Liquid Crystalline Networks

The mechanical properties of a homologue series of side-chain mesomorphic netM.orks were studied with a piezo-rheometer over frequencies ranging from 10~~
