Kinetically Enhanced Approach for Rapid and Tunable Self-Assembly of Rod-Coil Block Copolymers.
A facile approach is reported to process rod-coil block copolymers (BCPs) into highly ordered nanostructures in a rapid, low-energy process. By introducing a selective plasticizer into the rod-coil BCPs during annealing, both the annealing temperature and time to achieve thermodynamic equilibrium and highly ordered structures can be decreased. This process improvement is attributed to enhanced ...
متن کاملSupramolecular block copolymers by kinetically controlled co-self-assembly of planar and core-twisted perylene bisimides
New synthetic methodologies for the formation of block copolymers have revolutionized polymer science within the last two decades. However, the formation of supramolecular block copolymers composed of alternating sequences of larger block segments has not been realized yet. Here we show by transmission electron microscopy (TEM), 2D NMR and optical spectroscopy that two different perylene bisimi...
متن کاملAn evaporation-induced tri-consistent assembly route towards nitrogen-doped carbon microfibers with ordered mesopores for high performance supercapacitors.
Nitrogen-doped mesoporous carbon microfibers (NMCMFs) were prepared via an evaporation-induced tri-consistent assembly of a triblock copolymer, resols and prehydrolyzed tetraethoxy silane on natural silk followed by pyrolysis. The resultant NMCMFs inherit the advantages of both order mesoporous carbons (OMCs) and carbon microfibers (CMFs), such as uniform meso-channels, high surface area, high ...
متن کاملSelf-arrangement of nanoparticles toward crystalline metal oxides with high surface areas and tunable 3D mesopores.
We demonstrate a new design concept where the interaction between silica nanoparticles (about 1.5 nm in diameter) with titania nanoparticles (anatase, about 4 nm or 6 nm in diameter) guides a successful formation of mesoporous titania with crystalline walls and controllable porosity. At an appropriate solution pH (~1.5, depending on the deprotonation tendencies of two types of nanoparticles), t...
متن کاملSynthesis and assembly of core/shell nanospheres.
In this paper, we reported a new simple and effective method, osmotic membrane-assisted self-assembly, for fabricating massive interconnected macroporous silica monolith as catalyst supports. Using the method, we can prepare massive interconnected macroporous silica monolith with homogeneous structures beyond millimeter scale one time. Typically, silica/polystyrene and polystyrene/poly 4-vinyl ...
