Study on the substrate structure of medical mesh adhesive tape

采用中红外(MIR)光谱,开展了医用网纹易撕胶带基材的分子结构研究。实验发现:医用网纹易撕胶带基材的红外吸收模式主要包括:νasCH3-医用网纹易撕胶带基材、νasCH2-医用网纹易撕胶带基材-、νsCH3-医用网纹易撕胶带基材、νsCH2-医用网纹易撕胶带基材、νC=O-医用网纹易撕胶带基材、δCH2-医用网纹易撕胶带基材、δasCH3-医用网纹易撕胶带基材、δsCH3-医用网纹易撕胶带基材和ρCH2-医用网纹易撕胶带基材。医用网纹易撕胶带基材去卷积MIR光谱质量要优于相应的一维MIR光谱、二阶导数MIR光谱及四阶导数MIR光谱。医用网纹易撕胶带基材的主要化学结构为乙烯-醋酸乙烯酯的共聚物。拓展了MIR光谱在重要的医用器材(医用网纹易撕胶带基材)结构研究的应用研究范围。

The substrate structure of medical mesh adhesive tape molecular structure were characterized by the middle infrared(MIR)spectroscopy(including one-dimensional MIR spectroscopy,second derivative MIR spectroscopy,fourth derivative MIR spectroscopy and deconvolution infrared spectroscopy).The substrate structure of medical mesh adhesive tape infrared absorption modes includedνasCH3-substrate structure of medical mesh adhesive tape,νasCH2-substrate structure of medical mesh adhesive tape,νsCH3-substrate structure of medical mesh adhesive tape,νsCH2-substrate structure of medical mesh adhesive tape,νC=O-substrate structure of medical mesh adhesive tape,δ(CH2-substrate structure of medical mesh adhesive tape),δasCH3-substrate structure of medical mesh adhesive tape,δsCH3-substrate structure of medical mesh adhesive tape andρCH2-substrate structure of medical mesh adhesive tape.It was founded that the spectrum quality of deconvolution infrared spectroscopy were better than one-dimensional MIR spectroscopy,second derivative MIR spectroscopy and fourth derivative MIR spectroscopy.The main chemical structure of substrate structure of medical mesh adhesive tape was the copolymer of ethylene-vinyl acetat.It was demonstrated that the key roles of MIR spectrum in the analysis of structure of the important medical appliance(substrate structure of medical mesh adhesive tape).
