This study reports the application of UV induced "thiol-ene click reaction" by coupling the covalent bonds of venyl-terminated dendritic polyester (VTDP) and polyester (PET) fiber and resulting in the fabrication of hyperbranchstructured PET named as VTDP-PET fiber. The PET fiber or VTDP-PET fiber as additives were blended with styrene-butadiene-styrene modified asphalt (SBSMA) to prepare fiber/SBSMAs. Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive spectrometry, and X-ray photoelectron spectroscopy characterizations indicated that VTDP-PET fiber was linked with spherical three-dimensional dendritic molecular structure. Cone penetration, dynamic shear rheometer, multistress creep recovery, and thermogravimetric analysis tests showed that VTDP-PET/SBSMA exhibited enhanced resistance to flow, viscoelasticity, resistance against rutting, and thermal stability as compared to those of PET/SBSMA. The newly designed PET fiber and VTDP-PET fiber can be envisioned as effective alternative candidate for the fabricated of modified SBSMA with enhanced performances for practical applications in construction and highway industries.

“…To date, majority of the reported MOFs are polydisperse microcrystalline powders. However, the utility of MOF powders in industrial applications is limited by various problems, including dustiness, abrasion, clogging, low packing densities, mass transfer limitations, and mechanical instability during the packing process [12][13][14]. For example, when packing HKUST-1 powder into an adsorption column for capturing CH 4 , the mass transfer resistance increases with increasing column time because of the obvious decrease in pressure [15].…”

Although considerable achievements have been realized in recent years with respect to the syntheses of metalorganic frameworks (MOFs), majority of the developed MOFs are in the form of polydisperse microcrystalline powders, which cause dustiness, abrasion, and clogging and decrease pressure when used in industrial applications. Monolithic MOFs overcome these drawbacks and exhibit various promising characteristics. In this review, we present the recent advances associated with monolithic MOFs based on metal centers and a brief outline of the most prominent examples. Furthermore, the challenges and prospects associated with monolithic MOFs in terms of large-scale production and engineering applicability are analyzed based on our knowledge to conclude this review.

With their outstanding diversities in both structures and performances, newly emerging metal-organic frameworks (MOFs) materials are considered to be the most promising artificial catalysts to meet multiple challenges in the fields of energy and environment. Especially in absorption and conversion of solar energy, a variety of MOFs can be readily designed to cover and harvest the sun irradiation of ultraviolet (UV), visible and near-infrared region through tuning both organic linkers and metal nodes to create optimal photocatalytic efficiency. Nowadays, a variety of MOFs were successfully synthesized as powerful photocatalysts for important redox reactions such as water-splitting, CO2 reduction and aqueous environmental pollutants detoxification. MOFs applications in indoor-air VOCs pollutants cleaning, however, are less concerned partially because of limited diffusion of both gaseous pollutant molecules and photo-induced active species in very porous MOFs structures. In this mini-review, we focus on the major breakthroughs of MOFs as photocatalysts for the effective removal of indoor-air VOCs such as aldehydes, aromatics and short-chain alcohols. According to their nature of photoactive centers, herein MOFs photocatalysts are divided into two categories to comment, that is, MOFs with variable valence metal nodes as direct photoactive centers and MOFs with non-variable valence metal nodes but after combining other photoactive variable valence metal centers as excellent concentrated and concerted electron-transfer materials. The mechanisms and current challenges of the photocatalytic degradation of indoor-air VOC pollutants by these MOFs will be discussed as deeply as possible.
