| dc.description.abstract | 在此研究中，通過將 Carbopol 微凝膠與深共熔溶劑（DES）相結合，製備了不含聚合物網絡的物理顆粒共熔凝膠。DES 由氯化膽鹼作為氫鍵受體和檸檬酸作為氫鍵供體組成而成。當共熔凝膠含有超過 5 wt% Carbopol 濃度時能夠進行拉伸和剪切拉伸測試，同時表現出黏性表面並具有離子導電性。隨著 Carbopol 濃度的增加，拉伸強度增加，但黏著強度和離子導電性降低。具體而言，含有 10 wt% Carbopol 的共熔凝膠展示出優異的物理性能，包括拉伸強度為 45.3 kPa、可拉伸超過 1000% 應變、黏著強度為 4.66 kPa 和離子導電性為 0.43 mS/cm。紅外光譜分析顯示，DES 通過多個氫鍵在微凝膠之間起到物理交聯劑的作用，有助於形成顆粒共熔凝膠。因此，這些共熔凝膠也展現出自我修復性與可回收性能。此外，當共熔凝膠承受反復變形時，它們能夠產生穩定且一致的電阻信號，因此可應用於應變感測。 | zh_TW |
| dc.description.abstract | In this work, physical granular eutectogels were fabricated by incorporating Carbopol microgels into a deep eutectic solvent (DES) without a polymer network. The DES consists of choline chloride as the hydrogen bond acceptor and citric acid as the hydrogen bond donor. Eutectogels with more than 5 wt% Carbopol concentration are capable of undergoing tensile and lap shear testing, demonstrate sticky surfaces, and exhibit ionic conductivity. As the Carbopol concentration increases, the tensile strength rises, but the adhesive strength and ionic conductivity decrease. Specifically, a eutectogel containing 10 wt% Carbopol showcases outstanding physical properties, including a tensile strength of 45.3 kPa, stretchability exceeding 1000% strain, an adhesive strength of 4.66 kPa, and an ionic conductivity of 0.43 mS/cm. IR spectroscopy analysis reveals that DES acts as a physical crosslinker between microgels through multiple hydrogen bonds, facilitating the formation of granular eutectogels. Consequently, these eutectogels demonstrate self-healing and recyclability properties. Furthermore, they produce stable and consistent electrical resistance signals when subjected to repeated deformation, enabling their application in strain sensing. | en_US |
