摘要
采用紫外光接枝改性的方法将N 乙烯基吡咯烷酮 (NVP)单体接枝到聚 β 羟基丁酸酯和聚 β 羟基戊酸酯的共聚物 (PHBV)膜表面上 ,形成PHBV g PVP共聚物 ,从而提高其亲水性。并用接触角测定仪、傅立叶红外光谱仪和扫描电镜进行了分析表征。结果表明 。
The photo grafting polymerization of N vinylpyrrolidone(NVP) onto the surface of poly(β hydroxy butyrate co hydroxyvalerate)(PHBV) film with ultraviolet photo grafting method was studied. By means of water contact angle,Fourier transform infrared(FT IR) spectroscopy and scanning electron microscope(SEM), the grafting polymerization characterized was proved that PVP had been successfully grafted onto the surface of PHBV film and the hydrophilicity of PHBV film was improved greatly.
