“…[13,14] While progress has been made toward advanced brush architectures, current surface initiation strategies lack temporal and spatial control and, therefore, rely on a prepatterned initiator layer to template brush formation. Prepatterning has been demonstrated on a variety of substrates using top-down lithographic techniques, [15] such as photo-and interference lithography, [6] electron-beam lithography, [16][17][18] scanningprobe lithography, [19][20][21] and soft lithography. [22] In these cases, polymerization only occurs in regions where the initiator is present, resulting in patterned polymer brushes.…”

Ein einfacher Zugang zu gemusterten 3D‐Polymerbürsten basiert auf einer durch sichtbares Licht angeregten radikalischen Polymerisation. Die zeitliche und örtliche Kontrolle der Polymerisation ermöglicht die Musterung der Polymerbürsten ausgehend von einer einheitlichen Initiatorschicht durch eine einfache Photomaske (siehe Bild). Durch Änderung der Lichtintensität können unter anderem gemusterte Polymerblöcke und komplexe 3D‐Strukturen aufgebaut werden.

“…22 As illustrated in Scheme 1, initiator-modified graphene/Cu was placed in a polymerization solution to grow polymer brushes via SI-ATRP. [23][24][25][26] Subsequently, the entire substrate was immersed in an iron (III) chloride aqueous solution to etch away the copper foil. After copious water rinsing, a freestanding and transparent polymer@graphene floating on the water/air interface could be clearly observed (Figure 1a).…”

Compared with inorganic two-dimensional (2D) materials, such as graphene and transition metal dichalcogenides, organic 2D materials are believed to possess more interesting chemical and biological properties for certain applications, such as separation membranes, smart surfaces, sensors, catalysis and drug delivery. However, the study of organic 2D materials is largely hindered because of the lack of effective methods to produce them. This paper presents a new type of organic 2D material, namely 'polymer@graphene 2D objects', that can be synthesized via a simple and scalable chemistry. Polymer@graphene 2D objects are made of functional polymer brushes that tether one end of the polymer chain on the surface of graphene sheets via non-covalent p-p stacking interactions. These materials are transparent, freestanding, lightweight, flexible, transferable to various substrates with good stability and are patternable into different structures. Their functionality can be tailored by changing the polymer brushes that are immobilized. In this paper, we demonstrate the applications of these 2D objects in the smart control of surface wettability and DNA biosensors. INTRODUCTION Two-dimensional (2D) inorganic materials including graphene 1-3 and various transition metal dichalcogenides 4-6 have received tremendous attention in the past decade because of their unique properties and wide applications in optics and electronics. These remarkable phenomena have recently attracted research interest in 2D organic materials, including 2D polymers 7-10 and quasi-2D polymers. [11][12][13][14][15] The focus has mainly been on their chemical and biological properties and their applications as separation membranes, smart surfaces and sensors, and for catalysis and drug delivery. However, the 2D polymers reported to date are only limited to very specific building blocks and microscale sizes because of the lack of robust methods to produce them. On the other hand, the preparation of quasi-2D polymers either requires the undesirable crosslinking of the materials, using expensive and opaque novel metal supports, or high-energy electron beams. 16,17 Therefore, the investigation of the fundamental properties as well as practical applications of these organic 2D materials have remained largely hindered.In this paper, we report the development of a new type of functional organic 2D material, namely 'polymer@graphene 2D objects' , which are prepared in a cost-effective and high-throughput manner. Polymer@graphene 2D objects are made of functional

“…Due to the strong bonding between both substrate-ligand and ligand-metal, the resultant electrodes are highly stretchable. [133] Furthermore, patterned stretchable metal interconnects could be fabricated based on this strategy. Various printing methods, including dip-pen nanolithography (DPN, a scanning probe lithography technique that uses an atomic force microscopy (AFM) tip to create patterns with different inks), inkjet printing, and screen printing ( Figure 4b), could be applied to selectively deposited catalytic moieties to polymer brush modified substrates depending on the requirement of pattern resolution.…”

Emerging next‐generation soft electronics will require versatile properties functioning under mechanical compliance, which will involve the use of different types of materials. As a result, control over material interfaces (particularly soft/hard interfaces) has become crucial and is now attracting intensive worldwide research efforts. A series of material and structural interface designs has been devised to improve interfacial adhesion, preventing failure of electromechanical properties under mechanical deformation. Herein, different soft/hard interface design strategies at multiple length scales in the context of flexible hybrid electronics are reviewed. The crucial role of soft ligands and/or polymers in controlling the morphologies of active nanomaterials and stabilizing them is discussed, with a focus on understanding the soft/hard interface at the atomic/molecular scale. Larger nanoscopic and microscopic levels are also discussed, to scrutinize viable intrinsic and extrinsic interfacial designs with the purpose of promoting adhesion, stretchability, and durability. Furthermore, the macroscopic device/human interface as it relates to real‐world applications is analyzed. Finally, a perspective on the current challenges and future opportunities in the development of truly seamlessly integrated soft wearable electronic systems is presented.
