N2 - Robust triboelectric nanogenerators that are inexpensive, flexible, transparent, and do not require rigid metal sheet current collectors are vital for next-generation energy/wearable electronic device/robot/self-powered sensor applications. In this study, a soft skin-like solid polymer electrolyte triboelectric nanogenerator (SPE-TENG) with the above characteristics (flexible, good transmittance, and 0.099 S m−1 conductivity) is fabricated using cellulose acetate from waste cigarette butts and branched polyethyleneimine (abbreviated as CA/bPEI composite film). The CA/bPEI SPE composite film can serve as tribopositive electrification and current collector layer and demonstrated excellent electricity generation performance with a power density of 7.54 W m−2 under a contact-separation working mode. Meanwhile, the SPE-TENG can drive small commercial electronic devices (such as an LED switch) and has demonstrated a high-pressure sensitivity of 6.42 V kPa−1 and ultrafast response/recovery time (~2–6 ms), enabling its application in artificial electronic skin for various motions and tactile sensing. Furthermore, due to bPEI's ability to absorb UV light waves, the CA/bPEI composite film also possesses exceptional UV-ray shielding properties. The proposed work utilized discarded cigarette butts to simultaneously protect the environment and create a multifunctional material that can be used for clean energy harvesting to power small electronic devices and sensors and block harmful UV rays.
