“…To probe the effect of gels on the morphology of JSs, we further used SEM images to observe the assembly morphology before (Figure 4d) and after (Figure 4e) polymerization of NIPAm. As shown inFigure 4e, the microspheres are filled in the framework of gels, which further suggests the successful polymerization of NIPAm monomers and the complete replacement of the air space by gels in the CPC structure 43. The controlled PBGs and thermosensitivity of the as-prepared JSs are attributed to the hydrogel framework filled in the CPC structures.…”

The design and development of Janus suprabeads (JSs) with multiple responses are highly desirable in the fabrication of functional nanomaterials. In this work, we report a triphase microfluidic strategy for the construction of JSs with temperature-magnetism-optics triple responses. Initially, macromonomer poly(methacrylic acid) (PMAA) obtained via catalytic chain transfer polymerization (CCTP) was grafted onto the polystyrene (PS) colloidal photonic crystals (CPCs) surface. Because abundant carboxylic acid groups in PMAA could coordinate cadmium ions for in situ production of fluorescent CdS quantum dots (QDs) after introducing sulfur ions, the as-prepared JSs were endowed with favorable optical properties. Meanwhile, the as-prepared Cd(2+)/PS CPCs were employed as a template to build JSs with temperature-magnetism sensitivity via the introduction of magnetic Fe3O4 and hydrogels. Finally, the fluorescence pattern was easily performed by using chalcogenides as "ink" to write on the pad, in which in situ reaction mechanism was involved in the response. The multiple responsive JSs show promising applications in sensor, display, and anticounterfeit fields.

“…A photonic lattice composed of spherical particles has directional independence, which induces structural color that is angle-independent. Additionally, humidity sensors [94]- [96], glucose sensors [97], salt sensing materials as a rewritable photonic paper (shown in Fig. 3(b)) [98], pH sensors, and solvent sensors [99], [100] were developed by many researchers using photocurable polymer nanocomposites.…”

Intelligent" polymer nanocomposites have been an intensely popular research topic for several decades. These materials are based on combinations of two technologies: 1) the bottomup synthesis of nanoparticles to assign a novel functionality and 2) the top-down photolithography of polymers to create desirable microstructures. Such intelligent nanocomposites are comprised of functional nanoparticles embedded in polymer mesh, and these nanoparticles enable polymers to display functions and properties that natural polymers cannot possibly show. Herein, we introduce and categorize intelligent polymer nanocomposites according to their functional applications. Three main categories are covered in this review: polymer nanocomposites with magnetic, optical, and biological functions. The statuses of this research field are covered, and the future directions of polymer nanocomposite research are discussed.

known that the optical properties related refractive index is an important parameter for ordered micro/nanostructures. Commonly, organic substances own lower refraction. Aiming at improving which, researchers introduce highly polarizable heteroatoms or rigid aromatic moieties. However, the maximum of refractive index is limited to 1.54-1.60, [3] which is far from the requirements of rapidly developing technologies. [4] Incorporation of inorganic materials with relative higher refractive index (TiO 2 , ZnO, ZnS, graphene nanoparticles, and Si) into an organic matrix is capable of enlarging the optical parameters to a great extent, generally up to a value of 2.5-3.0, [5] which offers more chances for the fabrication of novel ordered micro/nanostructures. Photonic crystals (PCs), for example, regularly arrange materials of high and low dielectric constants on the order of the wavelength of light. The photonic bandgap (PBG) prohibiting the propagation of light results from the sufficient dielectric contrast and appropriate geometry. The structural color therefore generates. Manipulating the propagation of light via micro/nanostructures meets the requirements for modern optical devices. [6] As a result, more efforts have been applied to devices consisting of micro/nanostructures of multiple materials, such as synthetic materials and biomaterials. [7] Besides optical properties, the strength and toughness of ordered micro/nanostructures are also improved based on the hybrid material. Meanwhile, the electric and magnetic features of inorganic dopants can also exactly assist the adjustability. Therefore, the hybrid can significantly improve performance compared with its constituent.This review emphasizes on applications sought (sensing, imaging, communication, photoelectricity, etc.), the materials used (silicon, metals, polymers, etc.), and the preparation methods employed (patterning, etching, deposition, etc.). We present an attempt to classify and compare some intensively reported micro/nanostructures of hybrid materials and/or heterogeneous structures, along with recent important developments in literatures. It is organized as follows: First, we summarize some fundamental physical principles and concepts in brief. Second, we particularly highlight artificial and natural laminar structures, represented by Bragg stacks (BSs) and butterfly wings, which have drawn much attention in the latest literatures. Next, the focus shifts to the preparation routes and materials adoption of colloidal crystals and their derived periodic arrays. A few examples of highly functional materials Recent advances in manufacturing and technology of ordered hybrid micro/ nanostructures have acquired many breakthroughs. With the aid of the cooperation of various materials, the ordered hybrid micro/nanostructures exhibit high-quality performance and mechanical stability and allow the modulation on the light-matter interaction in a controllable manner, thereby enabling a wide variety of innovative applications.
