Learn MoreFlexible supercapacitors have attracted increasing attention due to their unique soft and capacitive properties. However, for a conductive polymer-based electrode material, the mechanical properties, conductivity and the interface bonding with the electrolyte are all challenging.
Hence, developing flexible conductive adhesives with low resistivity, mechanical stability, and infrared shielding is crucial for improving flexible electronics performance. Low infrared emissivity is crucial for infrared stealth. Atmospheric transmission attenuates infrared radiation to varying degrees depending on wavelength.
Conductive hydrogels have great application potential in flexible electronic devices. Nevertheless, it is a huge challenge to fabricate multifunctional conductive hydrogels simultaneously integrated with high conductivity, self-healing performance, adhesiveness and anti-freezing ability.
Thermoplastic polyurethane granule (TPU, Changhong Plastic Co., ltd) was used as the polymer matrix of the flexible conductive adhesive. 1,4-Dioxane (C 4 H 8 O 2, Aladdin, 99.5 %) was used to disperse the silver flakes and ATO nanoparticles as well as to dissolve the TPU. 2.2.
Furthermore, compared with previously reported flexible conductive adhesives (Table S1), AFCAs can achieve superior electrical conductivity under lower silver loading levels, thereby potentially reducing manufacturing costs. Additionally, the electrical resistivity of AFCA9 was measured over 30 days under ambient conditions (Fig. 3c).
It is well known that electrode materials significantly impact the overall capabilities of supercapacitors. Traditional dry-material electrodes are primarily in powder form, which leads to discontinuous conductive paths and high interfacial resistance owing to the physical contact with conductive particles [19, 20, 21, 22].
