Silver nanowire films have a wide application prospect in flexible electronics, while it is a noticeable problem that the silver nanowires break due to the shear force under the mass production film cutting or extreme service conditions. In this paper, the shear fracture behaviour of silver nanowire films with different structural parameters was studied under the extreme shear failure tests. The load-displacement curve was obtained from the nano-indentation test, while the hardness H, the elastic modulus E and the plastic properties represented by the ratio of H3/E2 of silver nanowire films with different diameters and thicknesses were calculated. On the other hand, based on the load-displacement curve, the stress-strain curve can be obtained through the finite element method simulation. The plastic properties can also be judged by the lower limit of yield strength from simulated stress-strain curve. Combined with characteristic crack propagation range, the relationship between plasticity and shear fracture was found, which was further disclosed by in-depth microstructure analysis. The results show that the better the plasticity of silver nanowire films, the stronger the resistance to shear fracture.

“…In recent years, conductive polymer composite films prepared from a polymer matrix and conductive fillers have received more and more attention due to their unique magnetic, mechanical, optical, and chemical properties [ 7 , 8 , 9 , 10 ]. At present, polyacrylonitrile (PAN) [ 9 ], polyvinylalcohol (PVA) [ 11 ], PTFE [ 12 , 13 ], PVDF [ 14 , 15 ], polybutylene terephthalate (PET) [ 16 ], etc., are used as polymer matrixes, and commonly used conductive fillers mainly include graphene [ 4 , 17 , 18 ], CNTs, MXenes [ 8 , 19 , 20 , 21 , 22 , 23 ], metals [ 16 , 24 , 25 ], alloys [ 14 , 26 ], perovskite metal oxides [ 27 , 28 ], and so forth. These conductive polymer composite films exhibit good EMI SE.…”

“…These properties make it possible to apply in different occasions and environments. As a filler material with excellent electrical conductivity, silver has been widely used in conductive films [ 23 , 24 , 25 , 34 ]. However, due to the high toxicity of stannous chloride in traditional silver-plating chemical reagents and the high price of palladium chloride, it is necessary to find more ideal alternatives in practical applications.…”

Dopamine was used to modify polytetrafluoroethylene (PTFE) in order to obtain functional polydopamine (PDA) surface-modified PTFE microporous film (PTFE@PDA). Ag was deposited on the surface of PTFE@PDA using electroless plating in order to obtain Ag-wrapped PTFE@PDA film (PTFE@Ag). A liquid-phase chemical reduction method was employed to prepare nickel nanochains. A Ni@PVDF cast film was obtained by mechanically blended nickel nanochains and polyimide (PVDF). The above two films were hot pressed to give a flexible, ultra-thin, and highly effective electromagnetic shielding composite film with a “3+2” layered structure. IR, XRD, and TEM results showed the PTFE@PDA film surface was coated by a tight plating layer of Ag particles with a particle size of 100~200 nm. PTFE@Ag+Ni@PVDF composite film exhibited excellent electromagnetic shielding effectiveness, with the conductivity of 7507.5 S/cm and the shielding effectiveness of 69.03 dB in the X-band range. After a 2000-cycle bending, this value still remained at 51.90 dB. Furthermore, the composite film presented excellent tensile strength of 62.1 MPa. It has great potential for applications in flexible and wearable intelligent devices.

“…However, it is challenging to synthesize AgNWs with relatively long lengths (>20 μm) at smaller diameters (<20 nm), compromising the mid-IR reflectance. Tao et al have previously demonstrated long nanowire lengths to improve visible transmittance and reduce VIS haze . Hence, length plays an important role in achieving high VIS transmittance and is a parameter that should be investigated further in the future.…”

Heating requirements for residential and commercial dwellings result in significant energy consumption and deleterious environmental effects. Personal radiative thermal management textiles regulate the wearer’s body temperature by controlling the material’s intrinsic optical properties. Passive heating textiles suppress radiative heat losses and therefore significantly reduce the energy consumption required for building heating systems. Guided by an optical theoretical approach, a transparent radiation shield (TRS) is designed based on silver nanowires (AgNWs) that can suppress human body heat with simultaneous visible light transmittance anticipated for practical fabrics. We experimentally demonstrated a TRS with large infrared light reflectance (low emissivity of 35%) and a visible (VIS) transparency value of 75% (400–800 nm). The results are well corroborated by the Mie scattering theory and the wire-mesh equivalent sheet impedance model, which provide fundamental mechanism understanding and guidance toward higher performance. The TRS is fabricated by a simple, solution-processing method with thermoplastic elastomer protective layers, granting notable stretching capabilities, mechanical robustness, and conformability to any body shape or object. The rigorous theoretical strategy enables the scalable synthesis of low-emissivity and visibly transparent textiles for personal thermal comfort.
