“…Therefore, metal nanowires are ideal materials to replace indium tin oxide (ITO) [10,11], carbon nanotubes [12], graphene [13,14] and conductive polymers [ [15] to fabricate TCFs. Among metal nanowires, silver nanowires (AgNW) is the most promising candidate owing to excellent conductivity, relatively low cost and convenient fabrication [16][17][18][19][20][21][22][23][24].…”

Silver nanowire transparent conductive films (AgNW TCFs) were facilely prepared by screen printing conductive ink on a polyethylene terephthalate (PET) substrate, and the effects of ink compositions and oily stencil on the optoelectrical properties of AgNW TCFs were investigated in detail. 7.3 mg·mL-1 hydroxypropyl methylcellulose (HPMC), 4.12 mg·mL-1 AgNWs and 98T oily stencil allow the preparation of large-scale AgNW TCFs with high transmittance, low square resistance and high uniformity. The resultant screen printed AgNW TCFs possesses a sheet resistance as low as 13.0±0.6 Ω/sq, a transmittance of about 95.3% at 550 nm wavelength (deducting the background) and a haze of 3.86 (deducting the background), and can achieve a surface root mean square roughness of 3.33 nm, a film size of 15×20 cm2 and personalized pattern by means of the screen printing process. The transparent film heater (TFH) constructed by AgNW TCFs can rise to a usable temperature of 55°C at a low voltage of 4 V within 80 s. This process provides a simple strategy for fabricating uniform, patterned and large size AgNW TCFs for various devices.

“…The rapid development of wearable electronics and intelligent monitoring devices brings about increasing demands for transparent, exible and conductive lms with intelligent responses. [1][2][3][4][5][6] Because electromagnetic interference (EMI) and radiation oen adversely affect adjacent electronic devices and the human health, and sometimes cause tremendous economic losses, [7][8][9][10] transparent and conductive lms are required to possess satisfactory EMI shielding performances for practical applications. [11][12][13][14] One of the main challenges of conductive lms is to balance efficient EMI shielding efficiency and high optical transmittance.…”

“…A common strategy to construct electric conductive and optical transparent films is to coat conductive fillers on the surface of different polymer substrates, such as polyethylene terephthalate (PET), 16−18 polyimide (PI), 19 polycarbonate (PC), 20 and polyurethane (PU). 13,21 This strategy is restricted by the aroused dazzling glare and strong light reflection, which limit their practical applications. Therefore, substrates with high transmittance and high haze are desired for enhancing light scattering.…”

An optical transparent and hazy film with admirable flexibility, electromagnetic interference (EMI) shielding, and Joule heating performance meeting the requirements of optoelectronic devices is significantly desirable. Herein, a cellulose paper was infiltrated by epoxy resin to fabricate a transparent cellulose paper (TCP) with high transparency, optical haze, and favorable flexibility, owing to effective light scattering and mechanical enhancement of the cellulose network. Moreover, a highly connected silver nanowire (AgNW) network was constructed on the TCP substrate by the spray-coating method and appropriate thermal annealing technique to realize high electrical conductivity and favorable optical transmittance of the composite film at the same time, followed by coating of a polydimethylsiloxane (PDMS) layer for protection of the AgNW network. The obtained PDMS/AgNWs/TCP composite film features considerable optical transmittance (up to 86.8%) and haze (up to 97.7%), while satisfactory EMI shielding effectiveness (SE) (up to 39.1 dB, 8.2–12.4 GHz) as well as strong mechanical strength (higher than 41 MPa) were achieved. The coated PDMS layer prevented the AgNW network from falling off and ensured the long-term stability of the PDMS/AgNWs/TCP composite film under deformations. In addition, the multifunctional PDMS/AgNWs/TCP composite film also exhibited excellent Joule heating performance with low supplied voltages, rapid response, and sufficient stability. This work demonstrates a novel pathway to improve the performance of multifunctional transparent composite films for future advanced optoelectronic devices.
