【摘要】 采用动态流变学方法研究了尿嘧啶分子印迹丙烯腈与甲基丙烯酸共聚物(P(AN-co-MAA))铸膜液的流变行为。对于P(AN-co-MAA)共聚物铸膜液体系,其复合黏度η*,在振荡频率≤1.263 H z时,变化甚微,当振荡频率≥3.47 H z时,η*大幅度下降;当尿嘧啶含量为1%时,体系的η*最大,并且随振荡频率的增加,下降的幅度增大。在1%~3%的尿嘧啶含量范围内体系的黏度η随尿嘧啶含量的增加而增加,随温度的升高而降低,尿嘧啶含量越大,黏度随温度变化越敏感。更多还原

【Abstract】 The rheological behavior of P(AN-co-MAA)molecularly imprinted cast solution with the template molecular of uracil(URA) was investigated by dynamic rheological technology.The results show that: the viscosity of the copolymer cast solution depends very little on frequency when the oscillation frequency is below 1.263Hz,however,it decreases drasticly with the increase of frequency when the oscillation frequency is over 3.47Hz;when the concentration of URA is 1%,the viscosity of the cast solution reaches its maximum and decreases greatly with the growth of frequency.As the URA concentration within the range of 1%~3%,the viscosity of the cast solution increases with increasing of URA concentration,and decreases with the increase of temperature,and becomes more sensitive to temperature changes with higher URA concentration.更多还原
