Embodiment 1

[0040] 1.5g polyacrylonitrile and 100mgC 60 After mixing, move to the ball mill jar, and the ball mill jar is packed in the ball mill. Set the ball milling speed to 500 revolutions / h, the ball milling temperature to 20 degrees, start and stop once including: every turn for 10 minutes, stop for 20 minutes, so that the mixture is obtained after 12 consecutive starts and stops, and the mixture is dissolved in DMF to form Spinning solution with a mass fraction of 10%. Inject the spinning solution into the container of the spinning device, set the voltage to 20kv, and set the receiving distance to 15cm. After spinning, the non-woven fabric was collected for morphology characterization.

[0041] From figure 1 It can be seen from the figure that although the thickness of the obtained composite nanofibers is not uniform, there is no large-scale aggregation of fullerene particles in the thickness of the obtained composite nanofibers.

Embodiment 2

[0043] 1.5g polymethylmethacrylate and 100mgC 60After mixing, move to the ball mill jar, and the ball mill jar is packed in the ball mill. Set the ball milling speed to 600 rpm / h, the ball milling temperature to 20 degrees, start and stop once including: 15 minutes per revolution, stop for 30 minutes, so that the mixture is obtained after 12 consecutive starts and stops, the mixture is dissolved in DMF, and the mass The fraction is 12% spinning solution. Inject the spinning solution into the container of the spinning device, set the voltage to 15kv, and set the receiving distance to 10cm. After spinning, the non-woven fabric was collected for morphology characterization.

[0044] From figure 2 It can be seen that fullerene and polymethyl methacrylate form a uniform composite nanofiber, and there is no phenomenon of large-scale aggregation of fullerene.

Embodiment 3

[0045] Embodiment three: 1.5g polyvinylcarbazole and 100mgC 60 After mixing, move to the ball mill jar, and the ball mill jar is packed in the ball mill. Set the ball milling speed to 600 rpm / h, the ball milling temperature to 20 degrees, start and stop once including: 15 minutes per revolution, stop for 30 minutes, so that the mixture is obtained after 12 consecutive starts and stops, the mixture is dissolved in DMF, and the mass The fraction is 12% spinning solution. Inject the spinning solution into the container of the spinning device, set the voltage to 15kv, and set the receiving distance to 10cm. After spinning, the non-woven fabric was collected for morphology characterization.

[0046] From image 3 It can be seen that fullerene and polyvinyl carbazole form uniform composite nanofibers, and there is no phenomenon of large-scale aggregation of fullerene.

Abstract

The invention discloses a fullerene-polymer composite nanofiber and a preparation method thereof. The preparation method comprises the following steps: conducting ball milling mixing on 2-20 wt% of fullerene and 80-98 wt% of a polymer material; dissolving the uniformly mixed mixture in a solvent, and thoroughly stirring to obtain a spinning solution; and preparing the uniformly stirred spinning solution into the fullerene-polymer composite nanofiber by an electrospinning method. The method provided by the invention solves the problem of incompatibility of fullerene and polymer material in solvent; meanwhile, the invention can greatly improve addition amount of the fullerene; and under high addition amount of fullerenes, the prepared composite nanofiber shows no phenomenon of fullerene particle aggregation.

Description

technical field [0001] The invention relates to the field of nanofiber materials, in particular to a fullerene-polymer composite nanofiber and a preparation method thereof. Background technique [0002] Currently, C 60 、C 70 Such fullerene materials have attracted much attention due to their unique structures and properties, and have become an important choice in the fields of physics, chemistry, materials and life sciences. The highly symmetrical closed-shell football-like molecular structure of fullerene determines that it has unique physical and chemical properties. Various chemical modifications of fullerene have various unique properties, such as fullerene polymer derivatives as functional The material has good application value in optoelectronics, bioactivity, catalysis, lubricants, etc. [0003] Nanofiber is a nanomaterial with a quasi-one-dimensional structure. It has a high aspect ratio similar to carbon nanotubes. In addition to its excellent mechanical properti...
