“…Because is hard, relatively insoluble, and a highmelting material [38], PAN is used to develop carbon fibers by stabilization, carbonization, and graphitization under controlled conditions [39,40]. PAN is also used in development of nanofibers [41,42], microcapsules/microspheres with diverse application (such as foam targets, carbon molecular sieve, cargo storage, or medical instruments) [43], semiconductor PAN powder (10 -10 S/cm < conductivity < 10 -3 S/cm when treated at 285-300°C) [44], or in the treatment of metals [45].…”

The aim of our research was to conduct a computational study on helical geometries of several homopolymers. Simple helix of polymers with seventeen (poly(lactic acid)) or eighteen (poly(1-chloro-trans-1-butenylene), poly(1-methyl-trans-1-butenylene), poly(1,4,4-trifluoro-trans-1-butenylene), polyacrylonitrile and respectively polychlorotrifluoroethylene) monomers were investigated. The X, Y, and Z coordinates obtained after optimization of the geometry of polymers were used as input data to identify the rotation and translation of the coordinates and respectively the coefficient of the helix. The values of interest were calculated by minimization of residuals using two different protocols. The first protocol investigated the whole polymer by imposing (step 1) or not (step 2) a fixed value of the helix coefficient. The second protocol investigated by minimization of residuals if the monomer (one or two) from each end of the polymer is or not an outlier of the helical geometry of the polymer.

“…The particular properties of polyacrilonitrile (PAN) [44], such as good thermal and mechanical stability, high tensile strength and high surface area, were attributed to the application of many fields such as fibers, film and membrane. Herein, we reported the preparation of a novel functional polymer brush of poly(acrylonitrile-g-glycidyl methacrylate) via the union of CRP and click chemistry (Scheme 1).…”

Abstract:A new approach for the preparation of polymer brush was developed via the union of controlled/"living" radical polymerization and click chemistry. The application of the approach realized the more quickly and accurate design and synthesis of the polymer brushes. A novel functional polymer brush of poly(acrylonitrile-g-glycidyl methacrylate) with tremendous application potential in the field of biology has been successfully synthesized via the new approach. The reaction conditions of click chemistry were optimized with the reaction time and the reactant ratio and judged from UV-vis spectra. Under the optimum of click chemistry, the novel functional polymer brushes were prepared. The GPC, FTIR analyses, 1 H NMR spectrum and TGA were employed to ensure the successful synthesis of poly(acrylonitrile-g-glycidyl methacrylate) polymer brushes.

“…Since electrode material is critical to the performance of a supercapacitor, numerous materials such as conventional carbon materials, transition metal oxides (TMOs) and conducting polymers have been widely designed and prepared [4][5][6] . Of these materials, transition metal oxides are considered as ideal electrode materials for supercapacitors due to their low cost, environmental benignity, high power density and good specific capacitance [7][8][9] .…”
