A triboelectric nanogenerator based on food packaging Aluminium foil and Parafilm for self-powered electronics

Abstract

The increasing food packaging waste is a severe concern for air, water, and soil pollution. In this research work, a triboelectric nanogenerator (TENG) is fabricated using waste food packaging Aluminium cover foils and laboratory parafilm for the first time. The device novelty lies in the selection of the materials; parafilm and food packing Aluminium cover foils. The proposed TENG produced an output voltage and instantaneous power density of ∼4 V and 11.8 nW cm −2 , respectively, by hand excitation force. Further, TENG can easily power up 85 commercial light-emitting diodes, digital watch, thermometer, and calculator with the help of charged capacitor. The proposed TENG demonstrated the ease of process, simplicity, cost-effectiveness, and reduction of pollution. Further, this TENG performance can be improved with other triboelectric materials and applied in selfpowered portable electronic device applications.

Employing impedance spectroscopy to investigate electrical conduction mechanism in polymer composite blends containing conductive masterbatch: PP/EVA/ (PP-g-MA/MWCNTS)

“…Antistatic packaging by the modification of commercial polymers such as polyethylene (PE), PP, and poly (ethylene terephthalate) (PET) is a cost-effective way for solving this problem. [15][16][17] Blending these commercial polymers can improve the purposive properties for antistatic applications such as mechanical properties, film processing, and barrier ability properties. 18,19 Also, in polymer blend nanocomposites the adjustability of morphology due to the segregated structure that is originated from the formation of disperse-matrix or co-continuous morphologies and the tendency of conductive nanoparticles for localization in favorite phase is desirable in academic and industry for fabrication of conductive polymer nanocomposites with widespread applications.…”

Parafilm Enabled Rapid and Scalable Delamination/Integration of Graphene for High‐Performance Capacitive Touch Sensor

“…Previously, parafilm has been used in electronic device architecture for different roles such as an encapsulate layer to avoid device degradation in moisture conditions, a substrate for making microfluidic paper-based device, a masking layer to make different patterned devices without using photo-lithography, and a dielectric material for flexible energy storage device and sensors, etc. [36][37][38][39][40][41] In this study, parafilm is employed as a versatile material, which satisfies multiple requirements: support layer during the graphene delamination, flexible substrate for graphene, and dielectric spacer in the design of graphene CTS devices. The unique advantage of using parafilm in the graphene transfer is that the parafilm layer itself can act as a flexible substrate for graphene, eliminating the need for transferring graphene to another substrate.…”

“…This particular property can be considered attractive because wearable electronics demands hydrophobic substrates to avoid damages and malfunction during the device operation. [39][40][41] Interestingly, parafilm has been used as a substrate and encapsulating layer in the fabrication of all solid-state supercapacitors, textile-based flexible electronics, and piezoresistive sensor for making attractive low-cost devices with high performance, due to its thermoplastic property and ductility, which provide good adhesion with any material of interest and can help in retaining the material properties. [36][37][38][39][40][41] When transferring graphene from the growth substrate to a flexible substrate, the process should allow a 100% transfer yield (delamination without any damages to graphene), [42][43][44] which is most important for practical device applications.…”

“…The bio-waste materials include peanut shells [23], sunflower husks [24], eggshells [25], rice husks [26], and fish bladder [27]. Household waste includes plastic bags [28], food packaging covers [29], rubber tires powder [30], and milk cartons [31]. The development of W-TENGs using a range of waste materials shows the potential for creating sustainable energy sources.…”
