本篇論文的動機是以軟粒子動力學模擬驗證團聯共聚物形成螺旋結構之可能性。

Stadler的研究群觀察到poly-Stytene-poly-Butadiene-poly-Methyl MethoAcrylate三團聯共聚物會產生螺紋的管柱結構，從螺距上推測可是雙螺旋或雙雙螺旋，而且同一系統中有左旋與右旋共存的現象。以軟粒子動力學模擬，我們觀察到改變三團聯共聚物 (AmB8-m)C24中的A與B的相對組成，可從一管柱結構，經一雙螺旋環繞管柱結構，過渡到另一管柱結構；而且我們可以從在模擬過程中，發現左旋雙螺旋結構到右旋雙螺旋結構的轉變。這些模擬結果基本上與實驗相符。

何榮銘老師的研究群發現在雙團聯共聚物中引入具有旋光性分子(例如polyStyrene-poly-L-Lactic Acid PS-PLLA)，可以使得(□N)ODT下降(相對於無旋光性分子之雙團聯共聚物如PS-PLA)，層板間距增加大，及產生一亞穩態的螺旋管結構。我們試圖以具有架橋點的軟粒子動力學模型來模擬旋光性的作用，我們發現(□N)ODT確實下降過程，但層板間距沒有明顯的改變；在模擬過程中只能發現類似W的亞穩態結構，並沒有發現如實驗上觀察到的螺旋管結構。推測其原因應該是旋光性的分子具有立體結構，而軟粒子動力學法中的粒子目前無法反映此一物理性質，如果要正確地反映旋光性分子的行為，勢必對軟粒子動力學法中之粒子間之聯結力場做些改變。
