Shanyu Zheng's 5 research works with 121 citations and 1,792 reads, including: Colossal electrocaloric effect in an interface-augmented ferroelectric polymer.
Zheng et al. discovered that a very large electrocaloric effect emerges in a terpolymer when pores are introduced with a sacrificial organic crystal with a low boiling temperature. The polymer interface around the pores has a large fraction of polarizable material, which gives rise to the large electrocaloric effect.
Electrocaloric effect (ECE)– based refrigeration uses solid-state materials as refrigerants in an electric-capacitive man-ner through efficient charge-discharge cycling, leading to a potentially more environmentally friendly cooling alternative with zero global warming potential and low indirect CO2 emis-sions (1, ).
Aug 11, 2022 · Here we report a class of EC polymer that exhibits an EC entropy change of 37.5 J kg (-1) K-1 and a temperature change of 7.5 K under 50 MV m (-1), a 275% enhancement over the state-of-the-art EC polymers under the same field strength.
