Tapered block polymer electrolytes have been developed and exhibited enhanced room temperature conductivity relative to poly(styrene-<italic>b</italic>-ethylene oxide) (P(S-EO)) non-tapered poly(s-<italic>b</italic>-oligo-oxyethylene methacrylate) (P(S-OEM)) counterparts.
High-molecular-weight multiblock copolymers are synthesized as robust polymer fibers via interfacial bioorthogonal polymerization employing the rapid cycloaddition of s-tetrazines with strained trans-cyclooctenes. When cell-adhesive peptide is incorporated in tetrazine monomer, resulting protein-mimetic provide guidance cues for cell attachment and elongation. As a service to our authors readers, this journal provides supporting information supplied by authors. Such materials peer reviewed...
Tapered block polymers are an emerging class of macromolecules with unique and diverse self-assembly behavior properties. Herein, we directly examine the manipulation self-assembled interfaces in poly(isoprene-b-styrene) (I-S)-based (BPs) by synthesizing non-tapered (I-S), normal tapered (I-IS-S), inverse (I-SI-S) BPs controlled monomer segment distributions. We provide first direct measurements interfacial mixing for these through X-ray reflectivity (XRR). The density profiles from XRR...
Quantitative morphological analysis is essential to the fundamental understanding of semiconducting polymers. Temperature modulated differential scanning calorimetry used determine amount crystalline and noncrystalline phases within regioregular poly(3-hexylthiophene) (rrP3HT). Careful optimization experimental conditions shows that glass transition rrP3HT consists three parts corresponding devitrification side chains, mobile amorphous fraction (MAF), rigid (RAF), consecutively. Measurements...
The enthalpy of fusion for a perfect, infinite poly(3-hexylthiophene) (P3HT) crystal () must be known to evaluate the absolute crystallinity P3HT. This value, however, is still ambiguous as different values have been reported using various experimental techniques. Here, we extrapolate extended chain crystals oligomeric P3HT molecular weight and obtain value 42.9 ± 2 J/g employing differential scanning calorimetry with correction based on grazing incidence small angle X-ray scattering data....
Both dry etching and wet are an integral part for the fabrication of semiconductor devices. However, both types can cause problems such as surface degradation, uncontrollability depth undercut. For instance, aqueous HF (wet etching) used to etch SiO2 films. During partial (SiO2 is not fully removed), it introduces some interesting phenomena adhesion degradation on morphology which present when etched. This paper reports first study systematical characterization after compares their different...
The thermal stability of ErAs nanoparticles and bulk-like powders, synthesized by pulsed laser ablation direct reaction, respectively, is investigated up to 700 °C in N2. Thermogravimetric analysis XRD are used monitor the decomposition temperatures crystalline compositions respectively. Degradation unagglomerated nanoparticle powders observed at 350 accompanied crystallization amorphous Er2O3. Mass balance suggests that mass loss occurs as a result arsenic volatilization rather than...
Mobile-amorphous-free crystals of a semiconducting polymer, poly(3-hexyl thiophene) (P3HT), were made via flow induced crystallization technique to yield that microns long while the other two dimensions 6 and 21 nm in size. Thermal analysis revealed melting point depression is described by Gibbs–Thomson (GT) equation resulting an interpretation physically sound. On contrary, contemporary enthalpy, which also shows below for infinitely sized crystal, yields results are nonphysical do not...
