Transparent heaters are widely used in technologies such as window 
defrosting/defogging, displays, gas sensing, and medical equipment. Apart 
from mechanical robustness and electrical and optical reliabilities, 
outstanding chemical stability is also critical to the application of transparent 
heaters. 
In this regard, we first present a 
highly flexible and large-area CuS 
transparent heater fabricated by a 
colloidal crackle pattern method with 
an optimized sheet resistance (Rs) as 
low as 21.5 Ω sq−1 at a ∼80% 
transmittance. The CuS transparent 
heater exhibits remarkable 
mechanical robustness during 
bending tests as well as high chemical 
stability against acid and alkali 
environments. In the application as a 
transparent heater, the CuS heater 
demonstrates a high thermal 
resistance of 197 °C W−1 cm2 with a 
fast switching time (
