英文摘要	We aimed to explore the effect of graphene films on polyimide-based humidity sensors in our published articles [1]. The results show that its sensitivity is 1.80 times that of the sensor coated with only polyimide film. After a lot of experiments in the later period, we believe that thicker polyimide film can lead to bigger wet hysteresis, which leads to measurement errors of this kind of sensor. We continue to explore the mechanism of action of graphene films by coating thinner polyimide films while keeping the graphene concentration consistent, and we found that the graphene film can effectively reduce the wet hysteresis effect and have a good measurement repeatability, as shown in Fig. 10(a) and (b) and its sensitivity are 1.53 and 1.61 times that of the sensor coated with thinner polyimide film when RH increases and decreases after coating the graphene film. The repeatability of the sensor is also good, Fig. 10(c) and (d) shows the repeatability test when only the polyimide film was coated and after coating the graphene film. We sincerely apologize to the editorial office and all readers. No conflict of interest exits in the submission of this manuscript, and manuscript is approved by all authors for publication. I would like to declare on behalf of my co-authors that the work described was original research that has not been published previously, and not under consideration for publication elsewhere, in whole or in part.
