Facile synthesis of silica-polymer hybrids via simultaneous RAFT process and hydroxyl-alkoxysilane coupling reaction
This study aimed at synthesis of silica particles grafted with better-defined homopolymers and block copolymers by tandem approach. Z-functionalized S-benzyl S’- (3-trimethoxysilyl)propyltrithiocarbonate (BTPT) was used as a couplable RAFT agent to synthesize the target inorganic-organic hybrids. Simultaneous coupling reaction and RAFT process using silica particles and BTPT as raw materials...

[Advanced Functional Materials] Manipulating the Motion of Gold Aggregates Using Stimulus Responsive Patterned Polymer Brushes as Motor
An important goal and major challenge of material science and nanotechnology
is building nanomotors for manipulating the motion of nanoparticles (NPs). Here, it is demonstrated that patterned, stimulus-responsive polymer brush microstructures can be used as motor arrays to manipulate the movement of gold NP aggregates in response to external stimuli that induce a conformational change in the bru...

Water-Soluble Starlike Poly(acrylic acid) Graft Polymer: Preparation and Application as Templates for Silver Nanoclusters
Water-soluble starlike polymers containing concentrated carboxyl groups were conveniently synthesized via the combination of “click” chemistry and atom transfer radical polymerization (ATRP). The starlike polymer was composed of a shorter polyacrylate main chain and longer poly(acrylic acid) side chains. Alkyne and azide groups were introduced to the structure units of the main chain b...

“Effects of Intermolecular Hydrogen Bondings on Isothermal Crystallization Behavior of Polymer Blends of Cellulose Acetate Butyrate and Poly(3-hydroxybutyrate) ”
Effects of hydrogen bondings (HBs) on the isothermal crystallization kinetics and mechanisms of poly(3-hydroxybutyrate) (PHB) in neat PHB and its blends with cellulose acetate butyrate (CAB), amorphous melts at the crystallization temperature, were investigated by using time-resolved Fourier transform infrared spectroscopy (FTIR). The FTIR investigation focused on the characteristic bands of PHB i...

Dynamic supramacromolecular self-assembly: deformable polymer fabricated nanostructures through host-controlled approach
Host molecules (a-CD) hierarchically thread onto the double grafts of the comb-copolymer EC-g-PCL-b-PEO from the outer block to the inner block in aqueous solution. Adjusting the molar ratio between a-CD and copolymer can induce these supramacromolecular complexes to dynamically and reversibly self-tune their fabrication from micelles (0-D) to cylinders (1-D) to vesicles (3-D) to sheets (2-D) like...

Novel Alternating Polymer Adsorption/Surface Activation Self-assembled Film Based on Hydrogen Bond
By combining hydrogen bonding layer-by-layer self-assembly and the stepwise chemisorption method, a new alternating polymer adsorption/surface activation self-assembly method was developed. First a layer of diphenylarnine-4-diazonium-formaldehyde resin (diazo resin or DR) is deposited on a substrate. In the following surface activation step, the diazonium groups on the surface couple with re...

80. Correlation between Gel-forming Ability, Supramolecular Aggregates and Main-chain Conformation of Dendronized Polymer Gelators
Dendronized polymer (DP) gelators were prepared via complexation of a dendritic gelator of the poly(urethane amide) dendron, which contains an ionizing carboxyl group on the apexes, with three positively charged polyelectrolytes. All these complexes could form organogels in toluene, and their gel properties were studied through determination of their minimum gelation concentration and charac...

30. Phase-separated structures in polymer mixtures with a thermotropic liquid crystalline copolyester as one component: composition dependence
The composition dependence of the phase-separated structures in the polymer mixtures consisting of a thermotropic liquid crystalline (LC) copolyester (X-7G) and poly(ethylene terephthalate) (PET) was investigated by means of polarized light microscopy. For this purpose the mixtures were solution-cast into thin films, followed by isothermal annealing at 270 °C. Although the final structure...
