摘要

在目前的研究中,通过用不同重量百分比(wt.%)的富马酸交联聚乙烯醇并用硫酸改性石墨颗粒对其进行增强,观察到了聚乙烯醇机械性能、热稳定性的提高和吸湿能力的降低。采用田口 L16 实验设计法,研究了改变交联时间和富马酸重量百分比对所得复合材料的影响。在工业迅速发展和竞争激烈的当代,制造商的首要目标是在规定时间内以最佳成本生产出高质量的产品。因此,为了节约成本和时间,作者采用了一种被称为 "灰色模糊优化 "的技术来平衡机械属性(韧性、伸长率和强度)和物理属性(吸水能力)之间的竞争目标。本方法旨在通过大大降低实际多响应优化问题的复杂性,减少实验费用,提高复合材料制造的效率。重点聚乙烯醇与不同重量百分比(wt. %)的富马酸交联,并用硫酸改性石墨颗粒进行增强。制备的复合材料的机械性能、热稳定性和吸湿能力均有所提高。采用田口 L16 实验设计法研究了改变交联持续时间和富马酸重量百分比对所得复合材料的影响。利用灰色模糊优化技术平衡了吸水率与韧性、伸长率和强度等机械属性之间的竞争目标。此外,还利用响应图和方差分析 (ANOVA) 测试来评估输入变量的贡献百分比,并提供模型的显著性。

Multi-response optimization of characteristics for graphite reinforced biodegradable PVA-fumaric acid cross-linked composite: A gray-fuzzy logic-based hybrid approach

In the current investigation, enhancement in the mechanical properties, thermal stability, and decrement in the moisture absorption capabilities of polyvinyl alcohol was observed by cross-linking it with different weight percentages (wt. %) of fumaric acid and reinforcing them along with sulfuric acid-modified graphite particles. The effects of altering the cross-linking duration and fumaric acid wt. % were investigated in the resulting composite using the Taguchi L16 experimental design method. As in this contemporary era of rapid industrial expansion and fierce competition, the primary goals of manufacturers revolve around the production of high-quality goods at optimal costs within a specified timeframe. Therefore, to save both cost and time, the authors have utilized a technique known as “gray-fuzzy optimization” to balance competing goals between mechanical (toughness, elongation and strength) and physical (water intake capacity) attributes. The present approach aimed to reduce the experimentation expenses and increase the effectiveness of composite manufacturing by considerably reducing the intricacy of practical multi-response optimization issues. Response graphs and analysis of variance tests were also utilized to calculate the percentage contribution of the input variables and provide model significance.

Highlights

  • Polyvinyl alcohol is cross-linked with different weight percentages (wt. %) of fumaric acid, and reinforced them with sulfuric acid-modified graphite particles.
  • Enhancement in mechanical properties, thermal stability, and decrease in moisture absorption capabilities were perceived for the fabricated composite.
  • Effects of altering the cross-linking duration and fumaric acid wt. % were investigated in the resulting composite using the Taguchi L16 experimental design.
  • Gray-fuzzy optimization technique was utilized to balance competing goals between water intake and mechanical attributes like toughness, elongation and strength.
  • Response graphs and analysis of variance (ANOVA) tests were also utilized to evaluate the percentage contribution of input variables and provide model significance.
