“…Bicontinuous phases have attracted a lot of attention from the research community owing to their subtle microtextures and the easy control over the length scale. Nanomaterials with bicontinuous textures has been extensively exploited in different research areas, namely, optical applications, data storage, electronic devices, energy conversion and storage, mass transport, drug delivery systems, and catalysis . Also, there are many reviews well documenting the progress in these areas .…”

In search of optimal structures for functional materials fabrication, the gyroid (G) structure has emerged as a promising subject of widespread research due to its distinct symmetry, 3D interconnected networks, and inherent chiral helices. In the past two decades, researchers have made great progress fabricating G-structured functional materials (GSFMs) based on G templates discovered both in nature and in the lab. The GSFMs demonstrate extraordinary resonance when interacting with light and matter. The superior properties of GSFMs can be divided into two categories based on the dominant structural properties, namely, dramatic optical performances dominated by short-range symmetry and well-defined texture, and effective matter transport due to long-range 3D interconnections and high integrity. In this review, G templates suitable for fabrication of GSFMs are summarized and classified. State-of-the-art optical applications of GSFMs, including photonic bandgap materials, chiral devices, plasmonic materials, and matamaterials, are systematically discussed. Applications of GSFMs involved in effective electron transport and mass transport, including electronic devices, ultrafiltration, and catalysis, are highlighted. Existing challenges that may hinder the final application of GSFMS together with possible solutions are also presented.

“…A typical glass has a refractive index between 1.45 and 1.65 in the visible spectral region, which implies that the refractive index of an AR lm must be between 1.20 and 1.28. The silica AR lms [7][8][9][10] prepared by a sol-gel technique have been widely used in solar energy application elds for their low refractive index, ease of preparation and low cost. The growth of silica sols with an acid catalyzed sol-gel process invariably leads to a linear structure with branches.…”

High-performance antireflection (AR) layers were prepared by depositing hierarchical nanoporous silica films on glass substrates. We designed a composite layer consisting of mesoporous silica nanoparticles (MSNs) and a mesoporous silica matrix. The introduction of bimodal nanoporous structures, i.e., independent nanopore formation within the MSN and within the matrix, was achieved by using surface-protected MSNs and a polymeric nonionic surfactant template during the fabrication process. A porosity of more than 40% was achieved for composite AR materials. The protrusion of MSNs from the matrix led to spontaneous formation of nanoscale roughness on the surface of the coatings, which enhanced the AR properties. The solid bonding of the MSNs to the nanoporous matrices played an important role in the achievement of high mechanical durability. The optimal nanoporous coating, which contained ca. 50 wt % MSN, exhibited high transparency (91.5-97.5%) and low reflectance (<2.2%), over the whole range of visible light wavelengths, and sufficient wear resistance.
