“…At the molecular level, redox coordinates the water‐soluble perylene diimide molecules to engage in π–π stacking interaction and thus promotes self‐assembly into superstructures [50] . At macromolecular level, the modification is achieved via a controlled chemical oxidation process, for example, the o ‐phenylenediamine was oxidized by ferric sulfate to form the poly( o ‐phenylenediamine)/Fe 2 O 3 composites [51] . The process then resulted rose‐like hierarchical microstructures which are self‐assembled from several tens of thin petals with a thickness of tens of nm.…”

Nature has endowed extraordinary beauty and functional significance in the form of biological morphology. Inspired by nature, biomorphic superstructures have been designed and synthesized from organic precursors in a laboratory. Although the complexity of synthetic superstructures is lower compared to natural forms, from an engineering point of view they possess competitive advantages such as low cost, ease of fabrication, and, occasionally, unexpected characteristics. Thus, there are still plenty of excitingly biomorphic superstructures waiting to be discovered.

“…Poly( o ‐phenylenediamine) (PoPD) is generally considered as a derivative of polyaniline (PANI) containing a repeating unit of 2,3‐diaminophenazine or quinoxaline . Consequently, the fabrication of PoPD based nanocomposites is acquiring attention since it can offer outstanding properties generated from the electrically conductive PoPD film and metal/semiconducting nanoparticles . Recently, new work has researched the rhodamine B dye degradation process by TiO 2 and PoPD core–shell nanocomposites as a photocatalyst .…”

The current study establishes the unprecedented involvement in the evolution and production of novel core-shell nanocomposites composed of nanosized titanium dioxide and aniline-o-phenylenediamine copolymer. TiO 2 @copoly(aniline and o-phenylenediamine) (TiO 2 @PANI-o-PDA) core-shell nanocomposites were chemically synthesized in a molar ratio of 5:1 of the particular monomers and several weights of nano-TiO 2 via oxidative copolymerization. The construction of the TiO 2 @PANI-o-PDA core-shell nanocomposites was ascertained from Fourier transform IR spectroscopy, UV-visible spectroscopy and XRD. A reasonable thermal behavior for the original copolymer and the TiO 2 @PANI-o-PDA core-shell nanocomposites was investigated. The bare PANI-o-PDA copolymer was thermally less stable than the TiO 2 @PANI-o-PDA nanocomposites. The core-shell feature of the nanocomposites was found to have core and shell sizes of 17 nm and 19-26 nm, respectively. In addition, it was found that the addition of a high ratio of TiO 2 nanoparticles increases the electrical conductivity and consequently lowers the electrical resistivity of the TiO 2 @PANI-o-PDA core-shell nanocomposites. The hybrid photocatalysts exhibit a dramatic photocatalytic efficacy of methylene blue degradation under solar light irradiation. A plausible interpretation of the photocatalytic degradation results of methylene blue is also demonstrated. Our setup introduces a facile, inexpensive, unique and efficient technique for developing new core-shell nanomaterials with various required functionalities and colloidal stabilities.

Abstract. Natural silk fibers were used as the template to synthesis biomorphic Fe 2 O 3 fibers. Silk fibers were first immersed into a Fe(NO 3 ) 3 solution and then sintered in air at high temperatures to produce the final Fe 2 O 3 fibers. Their microstructures, phases, and synthesis process were analyzed. The results show that these synthesized fibers retained the morphologies of silk faithfully. The concentration of the Fe(NO 3 ) 3 solution, the soak period, and the sintering temperatures all had the effect on the continuity of the biomorphic fibers. The fabrication process of biomorphic ceramic included the formation of Fe 2 O 3 and removal of their silk templates.
