Abstract

The primary objective of this study is to optimize the significant parameters (filler type, filler size, and content) for improving the performance of starch-based biocomposite films. The mathematical and statistical tools such as response surface methodology (RSM) and analysis of variance (ANOVA) were employed for modeling and optimization. To verify the different developed models, validation tests were also performed. The results showed that the RSM based central composite design (CCD) is an effective tool to predict the relationship between various input parameters and desired responses. Most of the desirable properties [Tensile strength, Young’s modulus, impact strength, water vapor transmission rate (WVTR), and opacity] of starch-based films were improved with the increase of filler content. The optimum values of input and response parameters are: filler content: 8.11 wt.%, filler size: 27.07 µm, filler type: walnut shell, tensile strength: 32.43 MPa, Young’s modulus: 333.338 MPa, elongation at break: 9.90 %, impact strength: 34.12 J/mm, WVTR: 1040.40 g m-2 24 h-1, ROD: 31.6918 weight loss%/day, transparency 58.60 %transmittance/mm, and solubility 27.06%.

基于响应面法的淀粉基生物复合膜的建模与性能优化

本研究的主要目的是优化重要参数(填料类型、填料尺寸和含量)，以提高淀粉基生物复合膜的性能。采用响应面法(response surface methodology, RSM)和方差分析(analysis of variance, ANOVA)等数理统计工具进行建模和优化。为了验证不同开发的模型，还进行了验证测试。结果表明，基于RSM的中心复合设计(CCD)是预测各种输入参数与期望响应之间关系的有效工具。随着填料含量的增加，淀粉基薄膜的拉伸强度、杨氏模量、冲击强度、水蒸气透过率(WVTR)和不透明度等大部分理想性能得到改善。最佳输入和响应参数为:填料含量:8.11 wt.%，填料尺寸:27.07µm，填料类型:核桃壳，抗拉强度:32.43 MPa，杨氏模量:333.338 MPa，断裂伸长率:9.90%，冲击强度:34.12 J/mm, WVTR: 1040.40 g - m-2 24 h-1, ROD: 31.6918失重%/天，透光率58.60% /mm，溶解度27.06%。
