摘要： A method comprising: providing at least one first composition comprising at least one conjugated polymer and at least one solvent, wet spinning the at least one first composition to form at least one first fiber material, hot-drawing the at least one fiber to form at least one second fiber material. In lead embodiments, high-performance poly(3,4-ethylenedioxy-thiophene)/poly(styrenesulfonate) (PEDOT/PSS) conjugated polymer microfibers were fabricated via wet-spinning followed by hot-drawing. In these lead embodiments, due to the combined effects of the vertical hot-drawing process and doping/de-doping the microfibers with ethylene glycol (EG), a record electrical conductivity of 2804 S·cm−1 was achieved. This is believed to be a six-fold improvement over the best previously reported value for PEDOT/PSS fibers (467 S·cm−1) and a twofold improvement over the best values for conductive polymer films treated by EG de-doping (1418 S·cm−1). Moreover, these lead, highly conductive fibers experience a semiconductor-metal transition at 313 K. They also have superior mechanical properties with a Young's modulus up to 8.3 GPa, a tensile strength reaching 409.8 MPa and a large elongation before failure (21%). The most conductive fiber also demonstrates an extraordinary electrical performance during stretching/unstretching: the conductivity increased by 25% before the fiber rupture point with a maximum strain up to 21%. Simple fabrication of the semi-metallic, strong and stretchable wet-spun PEDOT/PSS microfibers can make them available for conductive smart electronics. A dramatic improvement in electrical conductivity is needed to make conductive polymer fibers viable candidates in applications such as flexible electrodes, conductive textiles, and fast-response sensors and actuators.

摘要： A supramolecular polymer with living characteristics is provided based on small molecules or metal complexes of a planar or linear geometry and a polymer. The small molecules are solvophobic and can associate or assemble with each other through non-covalent interactions such as but not limited to metal-metal, π-π, hydrogen-bonding, and/or solvophobic-solvophobic interactions, in the modulation of the polymer. The polymer has affinity to the medium (e.g., solvent) and still interacts with the small molecules via non-covalent interactions such as electrostatic attractions to stabilize the associated/assembled small molecules. Varying the composition and/or length of the polymer can modulate the dimensions of the supramolecular polymer and the nanostructures therefrom. The two- or multi-component supramolecular polymer has active ends to support further supramolecular polymerization upon addition of small molecules of a planar or linear geometry. A process of two-component living supramolecular polymerization is also provided.

摘要： Provided are compositions and methods for making a variety of products. The methods involve mixing sucker ring teeth (SRT) protein and a plasticizer or a solvent to obtain a mixture of the SRT protein and the plasticizer. When the SRT is mixed with a plasticizer it is heated to between 32° C. and 195° C. to obtain an SRT protein melt. The melt is used to form a wide variety of products. When the SRT is mixed with a solvent, such as an organic solvent or an aqueous solvent, a solution of the SRT protein is formed, and is subsequently used to forming a product from the solution, wherein the product contains SRT protein.
