“…ENR/PD/zirconia (EPDZr) flexible and conductive films with improved hardness were successfully prepared by in-situ sol-gel reactions with varying amount of zirconium (IV)-n-propoxide (10,30, and 50 wt.%), while maintaining the percentage of PD constant. The electrical conductivity value of EPD film increased from 3.3 × 10 −4 to 1.9 × 10 −3 S/cm with 10 wt.% percolation threshold of zirconia precursor and decreased with 30 and 50 wt.%.…”

“…In another study, Yang et al [7] have prepared silicone rubber ablative composites with zirconia and showed the incorporation of zirconia increased the tensile strength of the composites. Many of the research works in literature have used synthetic plastics such as polyethylene terephthalate (PET), [8] poly(diazoaminobenzene) (PDAAB), [9] and polydimethylsiloxane (PDMS) [10] for the preparation of flexible and conductive devices which may hinder their industrial-scale production in terms of renewability, high production cost and sustainability. In our study ENR was used as a elastomeric biopolymer matrix, due to its biocompatibility, abundance in nature and low production cost.…”

The conductive and stretchable films with improved hardness are suitable for the fabrication of flexible electronic devices. This study describes the sol–gel technique to prepare a novel conductive and flexible film consisting of epoxidized natural rubber (ENR), doped polyaniline (PD) and zirconia. The zirconia networks were directly synthesized in‐situ in ENR/PD solution and flexible conductive composite film with improved hardness was obtained. The morphology study revealed the size of PD decreased significantly from 77.89 ± 43.95 nm to 4.32 ± 1.13 nm and highest electrical conductivity of 1.9 × 10−3 S/cm was achieved with 10 wt.% percolation threshold of zirconia precursor. The binding energy of Zr3d5/2 and Zr3d3/2 decreased, suggesting that zirconia was converted to the lower oxidation state. Furthermore, the shape of PD changed from spherical to rod‐like structure with root mean square value of 2 nm, while the hardness and reduced modulus improved to 1.72 MPa and 36.7 MPa, respectively.

“…[225,227] Several types of conductive fillers are commonly used to formulate conductive inks, such as metal nanomaterials, [105,241,301] liquid metal, [84,227] carbon-based nanomaterials, [67,302] and conjugated polymers. [303][304][305] The thin-film conductive network could achieve high transparency, [105] whereas 3D percolation networks embedded inside polymer matrices are usually opaque. [306]…”

“…Modification of internal polymer morphology by adding additives or blending with elastomer is commonly used to improve the electrical and mechanical properties of conjugated polymers. [303,392] The low intrinsic conductivity of PEDOT:PSS could be improved by adding additives like e.g., and H 2 SO 4 solution. [386,[393][394][395][396] Triton X-100, a nonionic surfactant, has also been used to modulate the surface tension and conductivity of PEDOT:PSS for the use in electrohydrodynamic printing processes.…”

Human-integrated devices include wearable and implantable devices for monitoring vital human signals or interacting with the human body. [1-3] The human-integrated devices needed to be tethered to the organs or the human skin for implementing their functions such as sensing and energy harvesting. [4-18] The economical, agile, customizable manufacturing, and integration of multifunctional device modules into networked systems with mechanical compliance and robustness will enable unprecedented human-integrated smart wearables [19-23] and usher in exciting opportunities in emerging technologies such as electronics, [24-29] wearable computation, [30-36] human-machine interface, [37-42] robotics, [43-48] and advanced healthcare. [49-54] The fabrication of stateof-the-art microelectronics involves hightemperature processing steps, which are generally incompatible with the flexible substrates (e.g., paper, polymer, fiber, etc.) [55-61] widely used in the wearable devices. Moreover, the current microfabrication technologies are not well positioned to process the emerging functional nanomaterials (e.g., nanowires [NWs] and 2D materials). [62-65] Such incomparability severely limits the pace of deploying these emerging materials (despite their unprecedented properties) in wearable and flexible device technologies. The additive manufacturing (AM) processes have emerged as potential candidates for addressing the earlier limitations of the current microfabrication technologies in fabricating flexible/wearable printed devices with diversified functionalities, e.g., energy harvesting/storage, sensing, actuation, and computation, leveraging advantages such as maskless processing, versatile ink formulation, low cost, low processing temperature, and scalability. [66-71] Researchers have devoted tremendous efforts to develop the related technologies, and several reviews have provided excellent discussions on the material formulation and process aspects of AM techniques. [63,72-79] However, to our best knowledge, there are few review reports about the ink-based additive nanomanufacturing of functional materials for human-integrated smart wearables. To fill this gap, here we review the recent progress in ink-based

“…Hopping process of charge transport involves two types: (1) thermionic emission also called phonon-assisted hopping, in which the carriers trapped in localized states absorb a phonon and classically jump to the next localized state, (2) direct tunneling related to passing of carriers between localized states if the electronic wave functions of the two localized states effectively overlap. The hopping of charge carriers highly depends upon the chain alignment [145][146][147], inter-chain length, inter chain interaction [148,149], the degree of oxidation levels as well as doping [150][151][152][153][154] and degree of disorder [155] along with morphology [149,156,157]. Thus the structure as well as morphology of CPs plays dominant role and those can be modified by several tools including chemical doping [158,159], thermal treatment [160][161][162], UV exposure [163] and ionizing radiation treatment [164].…”

Tailoring the characteristics of organic semiconductors including molecular semiconductor and conducting polymers is the frontline area of research for improving the performance of organic electronic devices. Electron beam treatment has been established as one of the easiest method in comparison to others like chemical doping, thermal processing, ozonolysis, UV and other ionizing radiation treatment, to tune the physico-chemical properties of organic semiconductors. High energy electron beam (EB) generated from an accelerators impinges energy to the material and causes several phenomena including doping, crosslinking, chain degradation, gas evolution, molecular structural modifications, oxidation and unsaturation. Such modifications lead to variation in electrical characteristics and consequently affect the overall device performances. In the present review we have focused on the different interaction processes of EB with organic semiconductors and its implications to tailor the performance of device comprising of it mainly gas sensors, field effect transistors, thermoelectric power generators and radiation dosimeters.
