Query: Temperature dependence of elastocaloric effect in natural rubber   The temperature dependence of the elastocaloric (eC) effect in natural rubber
(NR) is studied adiabatically and isothermally. A broad temperature span for eC
effect from 0 oC to 49 oC is observed. The maximum adiabatic temperature change
({\Delta}T) is 12 K at strain of 6 and occurs at 10 oC. These behaviors can be
predicted by the temperature dependence of strain-induced crystallization (SIC)
and temperature-induced crystallization (TIC). In isothermal condition, the
deduced {\Delta}T from Clausius-Clapeyron factor can agree with the direct
measurement at different temperatures. The eC performance of NR is compared
with shape memory alloys (SMAs). The potential of NR for a near room
temperature cooing application is primarily proved. This will open the SIC
research of NR towards eC cooling direction.
