Molecular Aggregation States of Imogolite/P3HT Nanofiber Hybrid

Polythiophene Nanofibril Bundles Surface‐Embedded in Elastomer: A Route to a Highly Stretchable Active Channel Layer

“…The bundles typically included 10–30 nanofibrils. The assembly is driven by the phase separation of the nanofibrils during spin‐coaing and the van der Waals interaction between the nanofibrils . Figure C shows the X‐ray photoelectron spectroscopy (XPS) spectra for the top surface, the middle (600 nm below the top surface), and the bottom surface.…”

Self-Assembly of Poly(3-hexylthiophene)-block-poly(γ-benzyl-L-glutamate) within Solution-Cast Films and Nanofibers

“…In the annealed sample, we also observed the appearance of the (200) reflection of the hexagonal packing of PBLG rods (peak 6′) at q = 13.1 nm −1 ( d = 0.479 nm), which is not seen in the as made film sample. Peaks 9′ ( q = 15.4 nm −1 ) and 10′ ( q = 16.3 nm −1 ) represent the π–π stacking of the P3HT block and the helical pitch distance of the PBLG α‐helices (see Figure S3 in Supporting Information for pure P3HT film data) …”

Partial Transformation of Imogolite by Decylphosphonic Acid Yields an Interface Active Composite Material

“…However, most of the studies aim to graft octadecylphosphonic acid or other phosphonic acids onto imogolite. [14][15][16][17][18][19][20][21][22] Yamamoto et al were the first to study the chemisorption of octadecylphosphonic acid (ODPA) on imogolite. [14][15] They concluded that ODPA adsorbs to the surface of imogolite.…”

“…The IR results only reveal the reactivity, but not the identity of the resulting phase. [14][15][17][18][19][20][21][22] XRD and SAXS identified changes in the organization of the product, but led to different interpretations. 16,[19][20] Finally, the investigations by microscopy do not have the required resolution to evidence isolated grafted nanotubes with clarity or lack complementary characterization.…”

“…16,[19][20] Finally, the investigations by microscopy do not have the required resolution to evidence isolated grafted nanotubes with clarity or lack complementary characterization. [16][17][18] A possible alternative reaction path for imogolite is the formation of bulk aluminum phosphonates. It is already known for the intercalation of gibbsite and kaolinite with phenylphosphonic acid (PPA) 23 , the modification of aluminum oxide by ODPA 24 and PPA 4 , and the modification of germanium imogolite by ODPA.…”
