To address these challenges, a novel conductive hydrogel was synthesized through free radical polymerization, incorporating laponite (LA), tannic acid (TA), polyacrylic acid (PAA), and polyacrylamide (pAAm). An innovative approach was employed to enhance LA's dispersion through ionic liquid (IL) in water through electrostatic interactions. The integration of TA, PAA, and PAAm with LA sheets via multiple hydrogen bonds resulted in excellent mechanical properties.

The ultrathin slice SEM image of the blend showed that polynorbornene and bitumen were compatible.

The blending of polynorbornene dramatically increases bitumen's thermal stability, raising the bitumen blend's decomposition temperature to 320°C.

The change results in physical parameters indicated that the polynorbornene addition had increased the hardness and thermal stability of the blends. Rheological tests also demonstrated that adding the polynorbornene significantly increased the complex shear modulus (<i>G</i>*) values of blend samples, indicating that under the same temperature conditions, the polynorbornene significantly improved the deformation resistance of bitumen.
