Embodiment 1

[0043] Weigh 50g of polyvinylpyrrolidone, dissolve it in 950ml of water, stir until it becomes a transparent solution, and then add 500mg of C 60 Powder, as for the ball mill tank, seal the ball mill tank well, place it in a low-temperature ball mill, set the speed at 600 rpm, and after 8 hours of operation, pour out the liquid (ball mill liquid, the same below), and centrifuge the liquid , take the upper liquid, which is the obtained C 60 - PVP complex solution. After the product was diluted, UV characterization was carried out. figure 1 C prepared for this example 60 -UV absorption diagram of the PVP complex, in the figure 340nm is C 60 The characteristic peak, the absorption peak at 450nm indicates that the two form a complex.

Embodiment 2

[0045]Weigh 50g of polyvinylpyrrolidone, dissolve it in 950ml of water, stir until it becomes a transparent solution, and then add 5g of C 60 Powder, as for the ball mill tank, seal the ball mill tank well, place it in a low-temperature ball mill, set the speed at 600 rpm, pour the liquid out after 10 hours of operation, centrifuge the liquid, and take the upper liquid, which is Income C 60 - PVP complex solution. After the product was diluted, UV characterization was carried out. figure 2 C prepared for this example 60 -UV absorption diagram of the PVP complex, in the figure 340nm is C 60 The characteristic peak, the absorption peak at 450nm indicates that the two form a complex.

Embodiment 3

[0047] Weigh 50g of polyvinylpyrrolidone, dissolve it in 245ml of water, stir until it becomes a transparent solution, and then add 500mg of C 60 Powder, as for the ball mill tank, seal the ball mill tank well, place it in a low-temperature ball mill, set the speed at 600 rpm, pour the liquid out after 8 hours of operation, centrifuge the liquid, and take the upper liquid, which is Income C 60 - PVP complex solution.

Abstract

The invention discloses a fullerene-macromolecule composite and a preparation method thereof. The preparation method includes the steps of firstly, dissolving macromolecular materials in water and stirring uniformly to obtain a clear solution; then, adding fullerene into the clear solution and subjecting the mixture to ball milling in a low-temperature ball mill; finally, centrifuging ball milling liquid to obtain supernatant liquid, namely the fullerene-macromolecule composite. By the preparation method, solid-liquid composition substitutes for solid-phase composition, so that the problem of loss during transfer of pure-solid materials is solved thoroughly, and preparation cost is further saved.

Description

technical field [0001] The invention relates to the field of fullerene materials, in particular to a fullerene-polymer compound and a preparation method thereof. Background technique [0002] Fullerene's unique molecular structure and chemical characteristics make it exhibit excellent performance in the fields of biology, medicine, and daily chemicals. To apply fullerenes to biological applications, it is first necessary to functionalize them to increase their water solubility and biocompatibility. The traditional methods mainly include: 1. chemical modification method, for example, modifying the water-soluble group hydroxyl group (OH-) outside the fullerene carbon cage; PVP) to coat the fullerenes, and improve the water solubility of the fullerenes with the help of the water solubility of PVP (Patent Request: 2004-19081 and Patent Publication No.: CN101166788A). Among the above methods, the chemical modification method is relatively cumbersome in preparation, involves mul...
