Special Issue Information

Dear Colleagues,

Hybrid materials, integrating two different materials at the nano or molecular scale, show superior properties or new synergetic characteristics compared with the two individual counterparts. There are numerous examples in nature where organic and inorganic materials are combined to generate hybrid materials with robust properties, e.g., bones, in terms of mechanical strength, and metalloenzymes, in terms of catalytic activity/selectivity. Taking such inspiration, tire industries have been using carbon black and textile fibers as fillers to improve properties of elastic rubbers for many years. Other than the amplification of materials performance, hybridization of two different materials sometime adds new synergetic characteristics or functionalities. One example is the use of gold nanoparticles as catalysts for CO oxidation discovered in 1980s. When combining two catalytically inactive materials, i.e., small gold nanoparticles supported on hematite, the hybrids show remarkable activity for CO oxidation. While those hybrids display incredible properties, the synergetic characteristics consistently arise from the complex interfacial interactions of the different materials. Developing new synthetic method to engineering the interface of different materials is not only of fundamental interest, but also provides new opportunities for technological innovation.

The research in hybrid materials is highly interdisciplinary given a tremendously large library of materials available to design hybrid materials across polymers, metals, inorganic oxides and ceramics. This Special Issue of Materials aims to provide a forum for researchers in hybrid materials community to discuss new advances in synthesis of hybrid materials. We welcome contributions in any form of hybrid materials, including nanomaterials, hydrogels, thin films, porous materials. The studies on fundamental correlations of synthesis-interface-synergetic characteristics of hybrid materials are particular encouraged.

Abstract
In this work, we fabricated porphyrin-loaded shape memory polymer (SMP) film by cross-linking micellar particles prepared by co-assembly of porphyrin compounds and amphiphilic macromolecules formulated by copolymerization of 2-butoxy ethanol (BCS), methyl methacrylate (MMA), butyl acrylate (BA) acrylic acid (AA), and diacetone acrylamide [...] Read more.
In this work, we fabricated porphyrin-loaded shape memory polymer (SMP) film by cross-linking micellar particles prepared by co-assembly of porphyrin compounds and amphiphilic macromolecules formulated by copolymerization of 2-butoxy ethanol (BCS), methyl methacrylate (MMA), butyl acrylate (BA) acrylic acid (AA), and diacetone acrylamide (DAAM). The experimental results revealed that this film was able to respond to the red light in terms of photothermal effect enabled by the porphyrin filler. The photothermal-triggered shape memory behaviors of the film were further examined in detail. It was noteworthy that this material was expected to have potential applications in the biomedical field due to the excellent biocompatibility of the porphyrin filler and the red-light source, which was optimal and safe enough for biomedical treatment.

Thermo-responsive hydrogel is an important smart material. However, its slow thermal response rate limits the scope of its applications. Boron nitride nanosheet-reinforced thermos-responsive hydrogels, which can be controlled by heating, were fabricated by in situ polymerization of N-isopropylacrylamide in the presence of boron nitride nanosheets. The hydrogels exhibit excellent thermo-responsiveness and much enhanced thermal response rate than that of pure poly(N-isopropylacrylamide) hydrogels. Interestingly, the hydrogels can be driven to move in aqueous solution by heating. Importantly, the composite hydrogel is hydrophilic at a temperature below lower critical solution temperature (LCST), while it is hydrophobic at a temperature above LCST. Therefore, it can be used for quick absorption and release of dyes and oils from water. All these properties demonstrate the potential of hydrogel composites for water purification and treatment.

In an effort to explore the use of organic high-performance lithium ion battery cathodes as an alternative to resolve the current bottleneck hampering the development of their inorganic counterparts, a rational strategy focusing on the optimal composition of covalent triazine-based frameworks (CTFs) with carbon-based materials of varied dimensionalities is delineated. Two-dimensional reduced graphene oxide (rGO) with a compatible structural conformation with the layered CTF is the most suitable scaffold for the tailored mesopores in the polymeric framework, providing outstanding energy storage ability. Through facile ionothermal synthesis and structure engineering, the obtained CTF-rGO composite possesses a high specific surface area of 1357.27 m2/g, and when used as a lithium ion battery cathode it delivers a large capacity of 235 mAh/g in 80 cycles at 0.1 A/g along with a stable capacity of 127 mAh/g over 2500 cycles at 5 A/g. The composite with modified pore structure shows drastically improved performance compared to a pristine CTF, especially at large discharge currents. The CTF-rGO composite with excellent capacity, stability, and rate performance shows great promise as an emerging high-performance cathode that could revolutionize the conventional lithium-ion battery industry.

Mesoporous materials are materials with high surface area and intrinsic porosity, and therefore have attracted great research interest due to these unique structures. Mesoporous titanium dioxide (TiO2) is one of the most widely studied mesoporous materials given its special characters and enormous applications. In this article, we highlight the significant work on mesoporous TiO2 including syntheses and applications, particularly in the field of photocatalysis, energy and biology. Different synthesis methods of mesoporous TiO2—including sol–gel, hydrothermal, solvothermal method, and other template methods—are covered and compared. The applications in photocatalysis, new energy batteries and in biological fields are demonstrated. New research directions and significant challenges of mesoporous TiO2 are also discussed.
