“…The unique properties of composites disseminated them in engineering [2], optics [3], the car industry [4], and many other fields. The electrical properties of composites formed the basis for numerous devices used in electrical and electronics [5][6][7][8][9]. Conductive polymer composites (CPCs) are also used in innovative technologies, such as thin chemical and biological sensors, solar cells, flexible electronic appliances, printed circuit boards, various resistors and actuators [10][11][12][13][14][15][16].…”

The Spatial Confining Forced Network Assembly, SCFNA, is a promising method for the preparation of high performance electrical conductive polymer composites, CPCs, by constructing a forced assembly conductive network in the polymer matrix. Because the present mathematical models for predicting electrical conductivities of CPCs were derived based on the free assembly of a conductive network, they were not suitable for predicting the electrical conductivities of the CPCs by SCFNA. A mathematical model for predicting the electrical conductivities of CPCs prepared by SCFNA was proposed in this article by introducing a compression ratio based on experimental data of the CPCs of PP/CF fabricated by SCFNA. The proposed model showed a good agreement with the experimental data of electrical conductivities prepared by SCFNA method. POLYM. COMPOS., 40:1819–1827, 2019. © 2018 Society of Plastics Engineers

“…Such films, particularly when formed wrinkled on a soft substrate via heating of the film or a prestrained substrate, are highly stretchable and flexible. A single layer of thin film or a layer-by-layer assembly can be used [ 64 ]. Additionally, CNTs can be modified in multiple ways to achieve biocompatibility and biodegradability [ 44 ].…”

“…With a 60 wt.% of PS@Ag, the sensor achieved a maximum elongation of about 80% and GFs, from lower to higher strains, of 17.5, 6, and 78.6. Whereas the previous CNT structure resulted in limited stretchability, the LBL assembly of SWCNT and thin polymer layers on a polycaprolactone (PCL) membrane created a piezoresistive, biocompatible strain sensor with a maximum strain of 100% and adjustable GFs between 5–13 [ 64 ]. While these previous strain sensors aim for high GFs, they sacrifice stretchability.…”

Flexible hybrid electronics (FHE), designed in wearable and implantable configurations, have enormous applications in advanced healthcare, rapid disease diagnostics, and persistent human-machine interfaces. Soft, contoured geometries and time-dynamic deformation of the targeted tissues require high flexibility and stretchability of the integrated bioelectronics. Recent progress in developing and engineering soft materials has provided a unique opportunity to design various types of mechanically compliant and deformable systems. Here, we summarize the required properties of soft materials and their characteristics for configuring sensing and substrate components in wearable and implantable devices and systems. Details of functionality and sensitivity of the recently developed FHE are discussed with the application areas in medicine, healthcare, and machine interactions. This review concludes with a discussion on limitations of current materials, key requirements for next generation materials, and new application areas.

“…Immersive LbL assembly, also known as “dip assembly,” is the most commonly used approach to fabricate LbL films and is generally performed by sequentially immersing substrates (of various sizes, shapes, amd so on) into a desired solution containing the layer materials, followed by several cleaning steps to remove unbound materials. , This process is repeated thrice and can be performed for different types of materials including planar, nonplanar, or particulate substrates. For instance, irregular substrates (e.g., graininess substrates) can be layered using an immersion-based strategy.…”

The complete recovery of tissues or cells damaged by an accident or illness is a major issue in medicine. With increasing medical costs and incidences of incurable diseases, this aspect is emerging as an important human health problem worldwide. However, reproducing actual cells and tissues is not easy because of the involvement of several variables. External environmental changes such as different pH levels, the presence of oxidants, and ultraviolet exposure can impair cell function or trigger cell death owing to the limitations of the cells. In addition, transplanted therapeutic cells die easily owing to inflammatory and immune responses. Efforts to overcome this problem through multilayer cell coating can provide avenues for diagnosis and basic cell biology studies owing to the following features of multilayer films: (i) high capacity available for attaching different biomolecules; (ii) natural replication of signal molecule diffusion across cells; and (iii) the possibility of cell patterning. Furthermore, light-triggered release from multilayer films achieves the delivery of biomolecules with a high spatiotemporal resolution. In this study, we reviewed the methods and recent innovations in multilayer cell coatings that demonstrate a strong potential for applications in biomolecule loading, cell patterning, and biosensors.
