摘要： 【目的】为解决抗结冰有机凝胶力学性能差的问题。【方法】以降冰片烯基十二氟庚酯（NDF）为单体，二降冰片烯基亚甲基双（异氰酸苯酯）（NMBI）为交联剂，液体石蜡为分散介质，通过开环易位聚合（ROMP）设计出自修复降冰片烯基含氟有机凝胶（NDFG）。【结果】NDFG凝胶呈现优异的力学性能（拉伸强度>0. 44 MPa）和防冰性能，在.20 ℃时保持 14. 86 kPa低冰剪切强度，即使经过 15次结冰-除冰循环，冰剪切强度仍低至 27 kPa。此外，动态氢键的断裂和重组赋予凝胶良好的自修复性能（自修复效率>86. 36%）。【结论】该有机凝胶是一种具有高力学强度的自修复防冰材料，在防冰领域具有良好的应用前景。

Abstract: ［Objective］ To address the issue of poor mechanical properties of antifreeze organogels.［Methods］ This work designed a series of self-healing norbornene-based fluorinated organogels（NDFG）through ring-opening metathesis polymerization（ROMP），using norbornene-based dodecafluoroheptanoate（NDF）as the monomer，dicyclopentadienyl dimethyl carbamate（NMBI）as the crosslinking agent，and liquid paraffin as the dispersion medium.［Results］The NDFG gel exhibits excellent mechanical properties（mechanical strength>0. 44 MPa） and anti-icing performance， maintaining a low ice shear strength of 14. 86 kPa at -20 ℃. Even after 15 freeze-thaw cycles，the ice shear strength remains as low as 27 kPa. In addition，the dynamic breakage and formation of hydrogenbonds endow the gels with good self-healing capabilities（self-healing efficiency >86. 36%）.［Conclusion］ The results showed that the organogels was an anti-icing material with excellent properties，becoming a promising application prospect in anti-icing field.
