Study on the inorganic–organic surface modification of potassium titanate whisker

Crystalline Structure, Synthesis, Properties and Applications of Potassium Hexatitanate: A Review

“…However, it is important to consider for short fiber polymer composites two significant aspects which have great influence on the properties of composites: The aspect ratio of reinforcement material and the interfacial adhesion between the polymer matrices and reinforcements [72]. In addition to the above, it is important to mention that PHT fibers often exhibits easy aggregation and poor dispersion in polymer matrix; moreover, the large surface energy difference between hydrophilic PHT and hydrophobic polymer could be the principal cause of the poor interfacial interaction, which leads to the decrease of the composite's performance [73,74]. For the above-mentioned reasons, it is necessary to use surface-treated fibers with a coupling agent, in order to improve both the homogenous distribution and the adhesion to the matrix.…”

A facile strategy to improve the encapsulation efficiency of polymer microcapsules containing water‐soluble salt cores

“…C and Si elements are additionally detected in the EDS spectra of OA‐modified APS and silane‐modified APS. Thereby it indicates that OA and KH‐570 are successfully grafted onto the APS surface …”

“…Hydrophobic materials were chosen as shells of the microcapsules to retain the cores' water solubility . However, the difference of surface energy between the water‐soluble cores and hydrophobic shells was distinct . Accordingly, the cores were difficult to be encapsulated into hydrophobic materials efficiently; the encapsulation efficiency of the resulting microcapsules was low.…”

Improving water-injection performance of quartz sand proppant by surface modification with surface-modified nanosilica

“…Nanoscale silica (denoted as nano-SiO 2 ) is a kind of inorganic powders with high specific surface area and a great number of unsaturated bonds [15,16]. In the previous works, we have prepared a series of super-hydrophobic nano-SiO 2 by in situ surface-modification, the silane coupling agent with hydrophobic groups was covalently bound to the nascent nano-silica surface and the wettability of nano-SiO 2 has been changed from hydrophilic to hydrophobic [17][18][19]. One of the prepared super-hydrophobic nano-SiO 2 has been utilized as a novel promising modifier for reversing the wettability of rock surface in the water-injection wells [20].…”
