“…Because ABC triblock copolymers can self‐assemble into various self‐assembled hierarchical structures, these kinds of triblock copolymers can act as the templates to achieve hierarchical mesoporous silicas 122–125 . For example, we have prepared hierarchical mesoporous silicas templated by PE‐ b ‐PEO‐ b ‐PCL or PE‐ b ‐PEO‐ b ‐PLA triblock copolymer as single templates, 126–128 obtaining mesopores of two different sizes, as confirmed through SAXS, TEM and Brunauer–Emmett–Teller (BET) analyses (Fig.…”

The self‐assembled structures formed through hydrogen bonding interaction of block copolymers in polymeric materials are interesting materials because of their potential applications in biomedicine, nanopatterning and photonics, taking advantage of their responsive and tunable properties. In this review, we discuss the self‐assembled nanostructures that can be obtained from hydrogen‐bonded diblock copolymer/homopolymer (A‐b‐B/C) and diblock copolymer (A‐b‐B/C‐b‐D) mixtures in the bulk and how these block copolymer mixtures can then be used to synthesize mesoporous silica, phenolic and carbon materials. © 2021 Society of Industrial Chemistry.

This personal account concerns novel recent discoveries in the area of mesoporous materials. Most of the papers discussed have been published within the last two to three years. A major emphasis of most of these papers is the synthesis of unique mesoporous materials by a variety of synthetic methods. Many of these articles focus on the control of the pore sizes and shapes of mesoporous materials. Synthetic methods of various types have been used for such control of porosity including soft templating, hard templating, nano-casting, electrochemical methods, surface functionalization, and trapping of species in pores. The types of mesoporous materials range from carbon materials, metal oxides, metal sulfides, metal nitrides, carbonitriles, metal organic frameworks (MOFs), and composite materials. The vast majority of recent publications have centered around biological applications with a majority dealing with drug delivery systems. Several other bio-based articles on mesoporous systems concern biomass conversion and biofuels, magnetic resonance imaging (MRI) studies, ultrasound therapy, enzyme immobilization, antigen targeting, biodegradation of inorganic materials, applications for improved digestion, and antitumor activity. Numerous nonbiological applications of mesoporous materials have been pursued recently. Some specific examples are photocatalysis, photo-electrocatalysis, lithium ion batteries, heterogeneous catalysis, extraction of metals, extraction of lanthanide and actinide species, chiral separations and catalysis, capturing and the mode of binding of carbon dioxide (CO ), optical devices, and magneto-optical devices. Of this latter class of applications, heterogeneous catalysis is predominant. Some of the types of catalytic reactions being pursued include hydrogen generation, selective oxidations, aminolysis, Suzuki coupling and other coupling reactions, oxygen reduction reactions (ORR), oxygen evolution reactions (OER), and bifunctional catalysis. For perspective, there have been over 40,000 articles on mesoporous materials published in the last 4 years and about 1388 reviews. By no means is this personal account thorough or all inclusive. One objective has been to choose a variety of articles of different types to obtain a flavor of the breadth of diversity involved in the area of mesoporous materials.

“…Silica derivative products as flame retardant material are intriguing for their good thermal-stability, non-toxicity and no poisonous gases release during burning process. [14][15][16][17] These materials have performed significant influence in enhancing flame retardancy and thermal stability feature of polymeric materials. [18] Ultra-violet (UV)-curing technology presents various advantages when it is compared to other conventional polymerization methods; these advantages include short polymerization time, high chemical stability, decrease in energy consumption, and relatively cheap production.…”

In this study mesoporous silica spheres (MPSs) and polyphosphoric acid based organophosphate ester flame retardant (FR material) material were synthesized and flame retardancy performance in acrylate-based polyurethanes (PUR) and polyester (PET) resins investigated. For this, both MPSs and FR material were synthesized according to literature and FR material was loaded into MPSs which takes the role of carrier. Loaded MPSs were put into UV curable PUR and PET resins and polymerized under UV radiation. Their characteristics were investigated by FT-IR, TGA, LOI, SEM and TEM. The results showed that FR material had excellent flame-retardant abilities for both PUR and PET series. The TGA curves suggested that synthesized FR material shows lower thermal stability at low temperatures than original materials however it showed good ability of char formation at higher temperatures, therefore improving the flame retardant property of samples. Moreover the LOI analysis showed that flame retardancy properties were improved significantly. The additive increased the LOI value from 20,5 and 21 to 26,5 and 27.
