Ace-resistant materials have long been plagued by critical challenges in practical applications, including insufficient durability and compromised stability under complex harsh conditions (e.g., high humidity, ultra-low temperature) . Therefore, developing advanced materials that synergistically integrate high mechanical strength, superior durability, and low ice adhesion strength remains of paramount significance. Herein, we rationally designed target materials by leveraging the complementary merits of fluorinated norbornene polymers (low surface energy, high mechanical strength) and PDMS (low elastic modulus, low surface energy). Specifically, the first network (fluorinated norbornene polymer) was constructed via ring-opening metathesis polymerization (ROMP) using Grubbs 2nd generation catalyst, with norbornenyl trifluoroethyl ester (NTF) and norbornenyl dodecafluoroheptyl ester (NDF) as comonomers, and di-norbornenyl ethylene glycol ester (NEG) as the cross-linker. The second network was fabricated through hydrosilylation reaction, employing Sylgard 184 Components A and B as monomer precursors and dimethyl silicone oil as a functional additive. Through the sequential polymerization strategy, a series of fluorinated norbornene/PDMS double-network organogels (NTDG/PDMS) with tunable dimethyl silicone oil contents were successfully synthesized. The physicochemical and functional properties of the as-prepared double-network organogels were systematically characterized. Experimental results revealed that the dimethyl silicone oil content exerted a prominent regulatory effect on the tensile strength and ice shear strength (τ₁ce) of the materials . As the silicone oil content increased from 0 to 80%, the tensile strength of NTDG/PDMS gels retained above 1.33 MPa, while the ice shear strength underwent a significant reduction from 211.59 kPa to 9.96 kPa (well below the 100 kPa threshold for icephobic materials ), accompanied by a gradual extension of icing delay time to 428 s. Mechanical durability assessment demonstrated that after 60 friction cycles, the ice shear strength of NTDG/PDMS-4 only increased from 9.96 kPa to 19.13 kPa (a marginal increment of 9.17 kPa) with minimal variation, manifesting exceptional ice resistance and structural robustness. Collectively, this double-network organogel integrates high mechanical strength, outstanding ice-resistant performance, and favorable friction resistance, thereby holding broad application prospects in the field of ice protection.
