Abstract:

Block copolymers can self-assemble to form nanoscale structures with domain spacing that depends on molecular weight, segment size, and the strength of the interaction between the blocks, represented by the Flory-Huggins interaction parameter, ??. In selective solvents, diblock copolymers are able to form micelles of various morphologies such as spheres, cylinders, vesicles, etc. In the bulk, microphase separation occurs, leading to various microstructures such as spheres, hexagonally packed cylinders, lamellae, and discontinuous phases. The ability to control both the length scale and the spatial organization of block copolymer morphologies makes these materials particularly attractive candidates for use as templates in the preparation of multiphasic nanostructured materials based block copolymers, which can act as templates for advanced hybrid inorganic/organic materials. Different examples of hybrid inorganic/organic materials based on block copolymers and nanostructured thermosetting systems will be presented at the conference. Atomic force microscopy will be mainly used to investigated the morphology and also electrical (electrostatic force microscopy (EFM), tunneling force microscopy (TUNA)) properties of designed multiphasic materials. Moreover, biohybrid inorganic/organic materials based on the bacterial cellulose modified with vanadium and titanium nanoparticles synthesized by solgel process will be discussed; also, bacterial cellulose modified with block copolymer will be focused upon.
