“…Hollow structure has attracted much attention due to its low mass density, high surface area and tailored structure with less agglomerated configuration [15]. These remarkable properties enable the hollow structure to possess great potential applications in catalysis, drug-delivery, sensors, fillers, microreactors and waste removal [16].…”

A series of hydrophobic hollow silica nanospheres with high specific surface areas and porous shells were successfully prepared through combination of a one-step reverse-phase microemulsion route and a simple post selective etching method. These materials owned porous shells and high specific surface areas, which were generated in the etching process. The distribution difference of organic groups among the solid nanosphere was innovatively utilized to create a different etching rate between the surface and the inner part of the solid silica nanosphere. After etching, the organic groups are still present on the surface which together with the rough surface give it hydrophobic properties and the contact angles can reach 150u. The reported materials showed good performance in the removal of 4-NP in water.

“…On the other hand, as a blowing agent, ADP releases inert gases to dilute the oxygen concentration in the air. Moreover, ADP is able to catalyze the hydrolysiscondensation of MTMS to form a Si-O-Si network structure with a low surface energy [29,[34][35][36][37][38][39], as shown in Scheme 1. According to the previous research [40], amine salts can interact with clays, causing clay nanoplatelets to deposit in stacks rather than as individual sheets.…”

Intumescent flame retardant and hydrophobic coatings, consisting of sodium montmorillonite (MMT), am moniu m d ihy dro gen ph os pha te ( ADP), an d methyltrimethoxysilane (MTMS), were prepared via in situ sol-gel and self-assembly techniques to acquire multifunctional cotton fabrics. The impact of MTMS concentration on hydrophobicity, fire resistance, thermal stability, and heat release behavior of the coated fabrics was investigated. A Si-O-Si network structure was generated via the hydrolysis-condensation reaction of MTMS, induced by the catalysis of ADP. After treated by the coating with 2.0 wt.% of MTMS, the cotton fabric with a total uptake of 22.7 wt.% achieved appreciable flame retardancy and hydrophobicity, as well as satisfactory thermal stability and heat release behaviors. Overall, this research provides a facile and effective approach to prepare flame retardant and hydrophobic cotton fabrics.
