中文摘要:
      为优化薄膜的制备工艺,采用均匀设计法,对聚乙烯醇(PVA)/甲基纤维素(MC)薄膜吸湿性进行了研究。试验以PVA/MC的体积比、甘油含量、pH、戊二醛浓度为考察因素,以吸湿率为考察指标,建立了4因素7水平均匀设计试验,应用SPSS 软件对数据进行了多元一次回归分析。结果表明:影响薄膜吸湿性的因素主次顺序为戊二醛浓度>甘油含量>体积比>pH;当PVA与MC体积比为2:1,甘油含量为0.11 mL/(100mL),pH为3.06,交联剂浓度为2.26×10-4 mol/L时,制得的薄膜吸湿率为2.68,抗张强度为42.17 MPa,伸长率为48.2%,性能较优。
英文摘要:
      Moisture absorption performance of PVA/MC film was studied using by uniform design method. Four factors seven levels uniform design test was set up. The factors were the volume rate of PVA/MC, glycerol dosage, pH, and glutaraldehyde (GA) concentration. The index was moisture absorption rate. The data was analyzed with multivariate linear regression by using SPSS statistical analysis software. The results showed that the significant order of influencing factors on moisture absorption rate of the film is GA concentration > glycerol > volume rate >pH; the optimal formula of the film is PVA /MC rate 2∶1, glycerol 0.11 mL/100 mL, pH 3.06, and GA concentration 2.26×10-4 mol/L; the manufactured film has moisture absorption of 2.68, tensile strength 42.17 MPa, and elongation 48.2%.
