“…One of the newly developed and promising template wetting methods is the SAINT (solvent‐annealing‐induced nanowetting in templates) method . In the SAINT method, polymer powders or films can wet the nanopores of porous templates in the presence of solvent vapors.…”

“…Recently, we applied the SAINT method to block copolymers and studied how the morphologies of the block copolymers can be controlled by the compositions of the annealing solvents . Polystyrene‐ block ‐polydimethylsiloxane (PS‐ b ‐PDMS) films were used and wet the nanopores of the AAO templates annealed in different solvent vapors (hexane, toluene, and mixtures of hexane and toluene).…”

In this work, the morphologies of polystyrene-block-polydimethylsiloxane (PS-b -PDMS) nanostructures using solvent-induced wetting in the nanopores of anodic aluminum oxide (AAO) templates are investigated. AAO templates with three different pore sizes (≈200, ≈60, and ≈30 nm) are used in this work to differentiate the effect of confinement and annealing solvents. Different from the results by the traditional wetting methods, two major effects are identified in affecting the morphologies. At larger pore sizes, the morphologies of the nanostructures are mainly affected by the annealing solvent. At smaller pore sizes, however, the morphologies are mainly controlled by the confinement effect (pore sizes).

“…In the template wetting methods, several ways can be used to introduce the polymer chains into the nanopores of the templates, such as the melt wetting method, the solution wetting method, the solvent‐annealing‐induced nanowetting in templates method, and the microwave‐annealing‐induced nanowetting method . For conjugated polymers, methods such as the melt wetting method or the microwave‐annealing‐induced nanowetting method may cause the problem of thermal degradation because of the high annealing temperatures.…”

Although many fabrication methods of conjugated polymer nanostructures have been developed, the effects of confinement on the morphologies, chain conformations, and optical properties of conjugated polymers are still not well understood. In this work, poly(9,9‐di‐n‐octylfluorene‐alt‐benzothiadiazole) (F8BT), a light‐emitting conjugated polymer, is used to fabricate nanotubes by a solution wetting method using anodic aluminum oxide templates. The property changes under the nanoscale confinement have been investigated. The morphologies of F8BT nanostructures are characterized by scanning electron microscope, transmission electron microscope, and laser scanning confocal microscope. The data show the hollow morphologies and no or low crystallinity of the nanostructures. The optical properties are also measured using UV–vis absorption, photoluminescence, and confocal Raman spectroscopy. The spectroscopy data indicate that F8BT polymer chains have less intermolecular interactions and coplanarity under the confinement effect.

Generation 3.5 poly(amido amine) dendron (G3.5) with 16 n‐butyl terminal groups containing an acrylamide monomer (AaUG3.5) was prepared by condensation between an amino focal group in G3.5 and 11‐acrylamidoundecanoic acid. AaUG3.5 was polymerized using poly(2‐methacryloyloxyethyl phosphorylcholine) (pMPC)‐based macro‐chain transfer agent via reversible addition‐fragmentation chain transfer (RAFT) radical polymerization to obtain amphiphilic diblock copolymers with different compositions. The diblock copolymers (PmDn) were composed of a hydrophilic pMPC block and hydrophobic pendant dendron‐bearing block, where P and D represent pMPC and pAaUG3.5, respectively, and m and n represent the degree of polymerization for each block, respectively. P296D1 and P98D3 formed vesicles and large compound micelles and vesicles, respectively, which was confirmed by light scattering measurements and transmission electron microscopic (TEM) observations. The large compound micelles formed from P98D3 could not incorporate hydrophilic guest polymer molecules, because the aggregates did not have a hydrophilic hollow core. In contrast, the vesicles formed from P269D1 could incorporate hydrophilic guest polymer molecules into the hollow core. © 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
