摘要(中)

雖然拉伸水凝膠奈米膜能夠獲取應力-應變曲線，但透過實驗了解內部結構和機制仍然具有挑戰性。因此本研究採用耗散粒子動力學的模擬方法來觀察伸長水凝膠奈米膜的微觀結構變化。觀察薄膜拉伸至斷裂點間的形態變化，並獲得相應的應力-應變曲線。系統性的分析微觀特徵，包括單條高分子的尺寸、鏈的尺寸及鍵長，以了解高分子網絡的變形。此外，也同時觀察高分子、鏈及鍵的斷裂。在薄膜中，界面區域的微觀結構與非界面區域的微觀結構不同，後者在伸長過程中承受較多的力。因此，隨著薄膜厚度的增加，非界面區域的貢獻變得更加明顯，導致機械性能進一步地增強。

摘要(英)

While stretching hydrogel nanofilms enables the acquisition of stress-strain curves, deciphering the internal structure and mechanisms through experiments remains challenging. In this work, dissipative particle dynamics simulations are employed to observe microstructural changes in elongated hydrogel nanofilms. The morphological changes of the film, up to the point of fracture, are observed, and the corresponding stress-strain curve is obtained. Microscopic characteristics, including polymer size, strand size, and bond length, are systematically analyzed to understand the network’s deformation. Additionally, the breakages of polymers, strands, and bonds are closely monitored. In a thin film, the microstructure of the interfacial region differs from that of the bulk region, with the latter enduring more forces during extension. Consequently, as film thickness increases, the contribution from the bulk region becomes more pronounced, leading to a further enhancement of mechanical properties.
