“…There is a growing interest in using EPD as a manufacturing method because of its compatibility with a vast material set including metals, 66 ceramics, 24,67 biomaterials, 68 polymers, 69 semiconductors 70 and composites, 71 and its speed, with depositions, typically lasting from seconds to minutes that can yield composite functional materials with several centimetres of thicknesses 72 . It has been successfully used in a wide variety of applications such as solid‐state lighting, 73 reactive materials, 74 energy storage, 75 drug delivery, 76 and photovoltaics 77 .…”

“…Some investigators applied EPD electrodes with special features such as the ability to change position during EPD and/or the ability to be reconfigured in order to form free‐standing films or turbulent gradients that is normally not attainable under standard conditions 67 . Of particular note, Anné et al applied a series of four counter‐electrodes to prepare a functionally graded net‐shaped femoral ball head 85 .…”

“…As mentioned above, EPD is well‐suited for multi‐material deposition and has been proven at industrial scale, but patterning of fine features and voids generally has not been possible 67 . Pascall and co‐workers previously demonstrated a new additive manufacturing technique called ‘Light‐Directed EPD’, which involves the use of photoconductive electrodes, laser‐cut photomasks and UV light to locally control the electric field 87,88 .…”

“…Pascall and co‐workers previously demonstrated a new additive manufacturing technique called ‘Light‐Directed EPD’, which involves the use of photoconductive electrodes, laser‐cut photomasks and UV light to locally control the electric field 87,88 . The use of laser‐cut photomasks, while reconfigurable, limits the scalability, the ability to be automated, and the resolution of the technique to 100 seconds of μm 67 . A more recent work expands on that of Pascall and co‐workers' by moving to a projection‐based system that not only removes the need to produce physical masks, but additionally enables an adaptable depositing pattern to form as a function of processing parameters.…”

The applications of electrophoretic deposition (EPD) to the development of electrochemical energy storage (EES) devices such as batteries and supercapacitors are reviewed. A discussion on the selection of parameters for optimizing EPD electrode performance, such as light-directed EPD, co-deposition of active materials such as metal oxides and materials manufactured with high porosity and fibrous properties is highlighted. Additionally, means for overcoming obstacles in the improvement of the mechanical properties, conductivity and surface area of EES materials are discussed. The exceptional benefits of EPD such as low cost, small processing time, simple apparatus requirements, homogeneous coatings, binder-free deposits and selective modification associated with thickness and mass loadings leading to effective EES electrode materials are highlighted. Finally, EPD processes have evolved as modern manufacturing tools to produce technologically improved solid electrolytes and separators for lithium-ion and/or sodium-ion batteries, and further research and development programmes are encouraged towards industrialisation.

“…Traditional composites produced using electrophoresis are limited to producing layers of materials perpendicular to the surface of the electrode, unlike its light-directed counterpart which enables the formation of patterns with different materials in-plane and layering one material over another with the disadvantages being scalability and the need to produce physical masks for each deposited layer. Optically controlled digital electrodeposition (ODE) has shown several advantages over conventional metal patterning processes by allowing dynamic patterning of custom micro-scale silver structures with high conductivities, resolution of 2.7 µm over a large scale in a matter of seconds [121]. The process involves the use of a solution with metal ions injected into an ODE chip followed by projecting images and alternating the electric field to form patterns.…”

Composite Reinforcement Architectures: A Review of Field-Assisted Additive Manufacturing for Polymers

et al. 2019

View full text Add to dashboard Cite

The demand for additively manufactured polymer composites with increased specific properties and functional microstructure has drastically increased over the past decade. The ability to manufacture complex designs that can maximize strength while reducing weight in an automated fashion has made 3D-printed composites a popular research target in the field of engineering. However, a significant amount of understanding and basic research is still necessary to decode the fundamental process mechanisms of combining enhanced functionality and additively manufactured composites. In this review, external field-assisted additive manufacturing techniques for polymer composites are discussed with respect to (1) self-assembly into complex microstructures, (2) control of fiber orientation for improved interlayer mechanical properties, and (3) incorporation of multi-functionalities such as electrical conductivity, self-healing, sensing, and other functional capabilities. A comparison between reinforcement shapes and the type of external field used to achieve mechanical property improvements in printed composites is addressed. Research has shown the use of such materials in the production of parts exhibiting high strength-to-weight ratio for use in aerospace and automotive fields, sensors for monitoring stress and conducting electricity, and the production of flexible batteries.

Electropatterning—Contemporary developments for selective particle arrangements employing electrokinetics

et al. 2023

View full text Add to dashboard Cite

The selective positioning and arrangement of distinct types of multiscale particles can be used in numerous applications in microfluidics, including integrated circuits, sensors and biochips. Electrokinetic (EK) techniques offer an extensive range of options for label‐free manipulation and patterning of colloidal particles by exploiting the intrinsic electrical properties of the target of interest. EK‐based techniques have been widely implemented in many recent studies, and various methodologies and microfluidic device designs have been developed to achieve patterning two‐ and three‐dimensional (3D) patterned structures. This review provides an overview of the progress in electropatterning research during the last 5 years in the microfluidics arena. This article discusses the advances in the electropatterning of colloids, droplets, synthetic particles, cells, and gels. Each subsection analyzes the manipulation of the particles of interest via EK techniques such as electrophoresis and dielectrophoresis. The conclusions summarize recent advances and provide an outlook on the future of electropatterning in various fields of application, especially those with 3D arrangements as their end goal.
