Embodiment 1

[0020] Embodiment 1: The specific steps of the technical solution of this embodiment are as follows:

[0021] 1. Raw material refining

[0022] Weigh 120g of CuCl into a 500mL beaker, add 300mL of concentrated hydrochloric acid with a mass concentration of 36~38%, and magnetically stir to dissolve it to obtain a saturated hydrochloric acid solution; then use a 1000mL beaker to measure 600mL of deionized water and transfer the saturated hydrochloric acid solution slowly Dilute it, stir it magnetically, and remove the upper light green clear liquid after centrifugation to obtain a white solid powder; repeat the above operation twice. Finally, it was washed with 3×100 mL of absolute ethanol, and the solid was transferred to a 250 mL Schlenk bottle. In an anhydrous and oxygen-free environment, magnetically stirred for 15 minutes, and allowed to stand for 20 minutes to remove the supernatant. Then wash with 2×100mL ether; dry N at room temperature 2 In the atmosphere, dry for use.

Abstract

The invention discloses a poly-ferrocene graft polymer and a preparation method thereof. Poly-ferrocene methyl chlorsilane (PFMCS) is used as a macromolecular evocating agent, and styrene (St) is used as a graft monomer. In the presence of a ferrocene-containing poly-ferrocene silane-g-polystyrene (PFS-g-PS) polymer is obtained by atomic transfer radical polymerization (ATRP), purification and drying. In a polymerization process, the ferrocene mass fraction content is regulated in the PFS-g-PS by controlling a polymerization process. The ferrocene in the polymer is evenly distributed into a polystyrene (PS) base body in a molecular dimension, has excellent comprehensive stability and can be used as a precursor for preparing a carbon nano tube and a new material for preparing the carbon nano tube in a one-step method.

Description

Technical field [0001] The invention relates to a polyferrocene grafted polymer and a preparation method thereof, in particular to a polyferrocene grafted polystyrene and a preparation method thereof. It uses polyferrocene methyl chlorosilane (PFMCS) and Styrene (St) is the main raw material, through the atom transfer radical polymerization (ATRP) method, the main chain contains ferrocene, the side chain is polystyrene (PS) polymer, which can be used to prepare high-quality hollow or iron-loaded polymers Of carbon nanotubes. Background technique [0002] Since Iijima discovered carbon nanotubes in 1991, they have received extensive attention due to their unique electronic properties, excellent chemical and thermal stability, and ultra-high mechanical properties. So far, a variety of methods for preparing carbon nanotubes have been developed, including: arc discharge method, laser ablation method, vapor phase catalytic growth method, chemical vapor deposition method, flame synthe...
