利用量子化学计算方法和基团贡献法,采集了61种聚酰亚胺分子结构模型单元的12种量子化学结构参数,并通过通径分析法筛选出5种影响该聚合物介电常数的主要因素;在此基础上,基于多元线性回归(MLR)和人工神经网络(ANN)方法构建了2种定量构效关系研究模型(QSPR),分析了模型的稳定性及预测能力. 计算结果揭示了5种结构参数与材料介电常数之间的内在关系——含氟量的自然律

则与介电常数则存在着负相关关系. MLR-QSPR模型具备较好的物理意义,ANN-QSPR则具有较好的精度,实验数据证明2种模型的平均误差均低于10%. 依据MLR-QSPR模型设计了5种不同含氟量的聚酰亚胺链节结构,结果显示含氟量的增加有利于降低材料的介电常数值,但当含氟量达到一定程度后,介电常数趋于稳定,与文献报道实验结果相一致;当含氟量为34%时(k-3),材料的介电常数最低,为2.02.
Using the quantum chemical calculation method and the group contribution method
12 kinds of quantum chemical structure parameters of 61 polyimide molecular structure model units were collected. In order to simplify the calculation process
a segment of the polymer chain was selected and saturated with methyl group
which was used as the model of the polyimide. Through the path analysis
5 main factors that affect the dielectric constant of the polyimide films were further screened. On this basis
the multiple linear regression (MLR) and artificial neural network (ANN) methods were constructed. Two quantitative structure-property relationship model (QSPR) were built
and the stability and prediction ability of the models were analyzed. The results revealed the intrinsic relationship between the 5 structural parameters and the dielectric constant
i.e.
the fluorine content

and the solubility parameter

of polyimide are positively correlated with the dielectric constant
while the most negative atomic net charge

and the side length

are negatively correlated with the dielectric constant. MLR-QSPR model has better physical significance and the ANN-QSPR has better accuracy. The accuracy of the models is validated by combining four structures: 6FDA-TriPMPDA
6FDA-TriPMMDA
6FDA-TPCF3PDA and 6FDA-TPCF3MDA in our lab. The experimental data show that the average error of the two models is lower than 10% under 1 kHz test condition. Five different fluorine-containing polyimide chain structures were designed according to MLR-QSPR model. The results show that the increase in fluorine content is beneficial to reduce the dielectric constant of the material
but when the fluorine content reaches a certain level
the dielectric constant tends to be stable
which are consistent with the experimental results reported in the literature. When the fluorine content is 34% (k-3)
the material possesses the lowest dielectric constant of 2.02. Based on the results of this study
it is believed that QSPR has a good application prospect and theoretical significance in designing new polyimide materials and predicting its properties.
