雖然具有許多優異的光電與機械性質，但是由於奈米碳管傾向聚集，不易均勻的分散在薄膜中。因此添加奈米碳管於複合材料中，一直無法獲得預期的作用。藉由π-π交互作用的形成，奈米碳管與聚芴高分子Poly(9,9-di-n-octylfluorenyl-2,7-diyl) (PFO)之間有很好的親和性。因此當PFO與非共軛高分子Poly(methyl methacrylate) (PMMA)在溶液中形成不同的液相時，摻入溶液中的奈米碳管有機會選擇性地分散於PFO液相中。於是，溶液中不同高分子液相的形成，成為調控奈米碳管分佈的方法。
此研究首先藉由改變溶液中的混摻比例、濃度、聚芴（Polyfluorenes）高分子側鏈長度與基材性質來探討混摻的高分子成份於析出薄膜中分佈的情形與調控機制。於溶液中添加奈米碳管後，發現奈米碳管於高分子溶液中有選擇性分佈的特性。由電子顯微鏡的觀察也證實了奈米碳管選擇性地分佈於PFO區域中。這個研究成果也說明了，不同的高分子液相會於溶液中形成，並影響奈米碳管的分佈。在析出薄膜中，也觀察到PFO板晶的成長與堆疊能夠驅使奈米碳管有不同的分散與排列行為。
於110 °C持溫時，PF12相會由原本的網狀分佈逐漸聚集成柱狀區域。散佈於PF12相內的的奈米碳管也逐漸以垂直於薄膜的取向聚集在柱狀區域中。因此，液晶相的流動與聚集也發現是造成奈米碳管於薄膜中垂直分佈的契機。

In this research, liquid phases of Poly(9,9-di-n-octylfluorenyl-2,7-diyl)(PFO) and Poly(methyl methacrylate)(PMMA)are developed in Toluene solution. By changing the compositional ratios, concentration, length of polymer side chain in solution, the morphology and two- phase distribution of spin- coated thin films are discussed. According to the pi-pi interaction between conjugated polymer and carbon nanotubes, we have observed the selective distribution of carbon nanotubes within PFO liquid phase. On spin-coated thin film, we’ve also observed the alignment of CNTs is further influenced by the stacking of PFO crystalline lamellae. The orientational alignment of CNTs could be developed at specific temperature and specific diameter of CNTs. When PFO is replaced by
Poly (9, 9-di-n-dodecylfluorenyl-2,7-diyl) (PF12), the flow of liquid phase at selected temperatures is motivated to form rectangular board-like domains. CNTs are found to align vertically in PF12 domains in order to maintain the interactions with the matrix of PF12.
