Abstract As ferroelectrics hold significance and application prospects in wearable devices, the elastification of becomes more important. Nevertheless, achieving elastic requires stringent synthesis conditions, while relaxor ferroelectric materials remains unexplored, presenting an untapped potential for utilization energy storage actuation electronics. The thiol‐ene click reaction offers a mild rapid platform to prepare functional polymers. Therefore, we employed this approach obtain by crosslinking intramolecular carbon‐carbon double bonds (CF=CH) polymer matrix with multiple thiol groups via reaction. resulting demonstrates pronounced relaxor‐type behaviour. This material exhibits low modulus, excellent resilience, fatigue resistance, maintaining stable response even under strains up 70 %. study introduces straightforward efficient construction ferroelectrics, thereby expanding possibilities
