Embodiment 1

[0028] Preparation of modified silane coupling agent:

[0029] 6-shogalenol was dissolved in toluene (the solid-to-liquid ratio of 6-shogalenol to toluene was 1g: 33mL), the reaction was heated up to 55°C, and the karstedt catalyst was added (the solid-to-liquid ratio of 6-shogalenol to karstedt catalyst 3g: 0.14mL) and continue to stir for 50min; then add triethoxysilane (the mass ratio of 6-shogaol to triethoxysilane is 1:0.51) into the constant pressure dropping funnel, and then slowly add it dropwise to In the solution, react at a constant temperature of 80°C for 23 hours after the dropwise addition; filter while hot, cool to room temperature, spin evaporate, dry, and recrystallize with ethanol to obtain modified triethoxysilane.

Embodiment 2

[0034] The difference between the preparation of the modified silane coupling agent and Example 1 is that the mass ratio of 6-shogaol to triethoxysilane is 1:0.58; the solid-to-liquid ratio of 6-shogaol to the karstedt catalyst is 3g : 0.17mL.

[0035] The difference between the preparation of a low-adsorption and antibacterial centrifuge tube is that the modified silane coupling agent is prepared in this embodiment.

Embodiment 3

[0037] The difference between the preparation of modified silane coupling agent and Example 1 is: the mass ratio of 6-shogaol to triethoxysilane is 1:0.55; the solid-to-liquid ratio of 6-shogaol to karstedt catalyst is 3g : 0.19mL.

[0038] The difference between the preparation of a low-adsorption and antibacterial centrifuge tube is that the modified silane coupling agent is prepared in this embodiment.

Abstract

The invention discloses a low-adsorption antibacterial centrifugal tube and application thereof, and relates to the technical field of centrifugal tubes. The preparation method of the low-adsorption antibacterial centrifuge tube comprises the following steps: pretreatment of the surface of the centrifuge tube: firstly, sequentially removing oil and cleaning organic impurities from the commercially available centrifuge tube, and then carrying out hydroxylation treatment on the surface of the centrifuge tube; and surface coating treatment of the centrifugal tube: dissolving the modified silane coupling agent in methanol, coating the surface of the centrifugal tube subjected to hydroxylation treatment with a film, airing, and carrying out heat treatment to obtain the coated centrifugal tube. The centrifugal tube prepared by the invention has excellent biological adhesion resistance, good stability, low adsorption performance and good antibacterial performance; and the hydrophobic property is still excellent at high temperature, and the wall hanging phenomenon of liquid is improved.
