應用田口方法品質分析於單壁奈米碳管的原材料

Abstract

對奈米科技而言，選擇正確單壁奈米碳管的規格而用來製造出需要的奈米碳管紙的品質是很重要的。本篇論文以一種統計實驗設計方法-田口方法來解決這個重要的問題。奈米碳管紙的過濾時間、平均導電性、表面面積、平均碳管直徑和孔徑當作品質特性，單壁奈米碳管的平均碳管直徑、純度和導電性當作重要參數。田口方法分析結果顯示奈米碳管的平均碳管直徑對於奈米碳管紙的過濾時間、導電性和平均碳管直徑有顯著的影響。奈米碳管的導電性對於奈米碳管紙的導電性也有重要的影響。後來由幾次實驗也驗證了田口方法的分析結論是正確的。結論，我們可以藉由控制單壁奈米碳管的重要參數來製造出所需要的奈米碳管紙的品質。

It is critical to choose the correct specification of carbon nanotubes (CNTs) from a CNT company in order to fabricate a desired quality of nanotube buckypaper (NBP). In this paper, a statistical experimental design method, Taguchi method with an L4 orthogonal array robust design, was applied to resolve this problem. Filtration, electrical conductivity, surface area, rope diameter and pore size of NBPs were considered as the properties. The rope diameter, purity and electrical conductivity of carbon nanotubes were chosen as significant parameters. As a result of Taguchi analysis in this study, rope diameter was determined to be the most influencing parameter on the filtration time, electrical conductivity and rope diameter of NBPs. The electrical conductivity of CNTs also had a principal effect on the electrical conductivity of NBPs. The optimal conditions were determined by using Taguchi method. There is good agreement that is being observed between the prediction and experiment. Consequently, desired NBPs can be fabricated by controlling the significant parameters of CNTs.
