“…The particle‐fluid interaction is an ability for particles to blend well with liquids by a capillary force caused by the wetting ability of liquids between particles [54] . When a polymer having hydrophilic and hydrophobic groups is adsorbed onto a hydrophilic porous matrix, the carboxyl group of the polymer is strongly attracted to the matrix to form a dense connection with the matrix, whereas the hydrophobic alkyl chain is not adsorbed into the pores due to the repulsive force with matrix [55] . As the Mg‐ST HNP has hydroxy groups (−OH) on the surface and the fluid surrounding the particles is an oil consisting of hydrophilic carboxyl groups and hydrophobic alkyl chains, the particle–fluid interaction depends on the functional group of the medium, resulting in a difference in wettability.…”

This paper proposes the fabrication of a new type of electrorheological (ER) fluid with ecoresorbable features as well as excellent electroresponsive performance. The proposed ER fluid consists of biocompatible Mg‐doped silica/titania hollow nanoparticles (ST HNPs) suspended in vegetable oils (canola, grapeseed, olive, and soy). The effects of biodegradable plant‐derived carrier liquids on the ER performance are analyzed. The polarizability and wettability of the fabricated ER fluids are studied. The high polarizability of the nanoparticles contributes to the highly electroresponsive performance by inducing electrostatic interactions between the nanoparticles under electric fields; this enables the formation of a rigid and strong fibril structure. A suitable wettability, which represents the favorable interaction between the oil and the nanoparticles, allows the nanoparticles to disperse evenly in the oil and prevents their aggregation, thereby making the formation of a rigid and strong fibrillar structure under the electric field easier.

“…On the other hand, some polymer particles filled the capillary pores since particle size was in the range of 100-1000 nm, which increased the impermeability of cement-based materials. Zhou [18] manufactured polymers with different functional groups and investigated the repelling water effect. The results of molecular dynamics revealed that the polarity carboxyl group of polymers adsorbed on the CSH surface, while hydrophobic carbon chains played a role like a gate and had an inhibiting effect when the cement paste contacted with water [18].…”

The results of molecular dynamics revealed that the polarity carboxyl group of polymers adsorbed on the CSH surface, while hydrophobic carbon chains played a role like a gate and had an inhibiting effect when the cement paste contacted with water [18]. Hou [3] found that tetraethoxysilane (TEOS) and nano-SiO 2 were used to modulate the transport properties: TEOS decreased the porosity of the pores smaller than 0.1 µm, while nano-SiO 2 blocked the pores of around 0.1 µm, and thus reduction in water absorption was achieved in the case of both.…”

Durability improvement is always important for steel–concrete structures exposed to chloride salt environment. The present research investigated the influence of a novel nano-precursor inhibiting material (NPI), organic carboxylic acid ammonium salt, on the mechanical and transport properties of concrete. The NPI caused a slight reduction in the strength of concrete at later ages. NPI significantly decreased water absorption and slowed down the speed of water absorption of concrete. In addition, the NPI decreased the charge passed and the chloride migration coefficient, and the results of the natural chloride diffusion showed that the NPI decreased the chloride concentration and the chloride diffusion coefficient. The NPI effectively improved the resistance of chloride penetration into testing concrete. The improvement in the impermeability of concrete was ascribed to the incorporation with the NPI, which resulted in increasing the contact angle of cement pastes. The contact angle went up from 17.8° to 85.8° for 0% and 1.2% NPI, respectively, and cement pastes became less hydrophilic. Some small pore throats were unconnected. Besides, the NPI also optimized the pore size distribution of hardened cement paste.

“…Light-colored synthetic asphalt (LCSA) binders were prepared using aromatic oil, petroleum resin, and various polymer modifiers. The bending beam test (BBR) results show that the binder prepared with SBS, EVA, and SBS + EVA had a better performance under low temperatures with better aging resistance in the seal pavement (Sengoz and Isikyakar, 2008;Tang et al, 2018;Zhou et al, 2020). He (2013) and Jin (2015) indicated that a network structure can be formed by the polymer modifiers in the LCSA binder, which significantly influences the performance at both high and low temperatures.…”

A uniform test design method was used to investigate the storage stability, wear resistance performance, anti-slide performance, and color durability of a colored emulsified asphalt seal mixture (CEASM). The optimal mix proportions of the seal mixture were determined, and the engineering test application and effect evaluation analysis were performed. The results show that the clay, silica fume, pigment, mineral aggregate, and emulsified asphalt contents in the prepared mixture ranged from 15-17, 12-16, 10-14, 28-32, and 25-32%, respectively. In practical engineering applications, CEASM with a molding thickness of 2-3 mm stored in liquid form has a good storage stability and wear resistance, which is suitable for manual scraping pavement or mechanical spraying construction. In addition, it has been shown that colored pavement has the advantages of low cost, safety, environmental protection, convenient construction, good durability, and rapid molding. The CEASM also has great application prospects in color repaving for non-color roads, the early maintenance of colored pavement, and road disease maintenance. The results guide colored pavement designs to improve the storage stability of CEASM and enhance the color durability and crack resistance of colored pavements.
