Abstract

The invention discloses a preparation method of a polybutylcyanoacrylate nanowire. The preparation method comprises the following steps of: preparing an oil-phase mixture, namely dispersing alpha-n butyl cyanoacrylate with the volume ratio of 0.2-0.3% and ethyl acetate with the volume ratio of 3-6% in acetone; preparing emulsified-phase mixture, namely dispersing a 5-8 g / L emulsifying agent and a 8-10 g / L stabilizer, wherein the emulsifying agent is sodium lauryl sulphate, and the stabilizer is dextran-70; carrying out interface emulsification polymerization reaction; and at room temperature, gradually dropwise adding the prepared oil-phase mixture into the prepared emulsified-phase mixture for carrying out interface emulsification polymerization. The preparation method disclosed by the invention has the characteristics of stable performance and no toxicity and no harm to a human body, animals and microorganisms.

Description

technical field [0001] The invention relates to a preparation method of poly(n-butyl cyanoacrylate) nanowires, and belongs to the technical field of biological carrier preparation methods. Background technique [0002] In recent years, with the research and development of nanomaterials, the research and development of nanobiomaterials has become a research hotspot in the field of international biotechnology. [0003] At present, the nanobiomaterial poly(butyl-2-cyanoacrylate) (PBCA) has also become a biomaterial studied by many experts and scholars. However, more researches are on nanoparticles, including nanospheres and nanocapsules, which are spherical or ellipsoid in shape, but the reduction of the size of nanoparticles will cause some problems. For most nanoparticles, for example, how to recover the sample after an experiment is a tricky problem, because once the nanoparticles are dispersed in solution, it is difficult to collect the nanoparticles from the solution unle...
