Fabrication and superhydrophobicity of fluorinated titanium dioxide nanocoatings

Synthesis and visible‐light‐derived photocatalysis of titania nanosphere stacking layers prepared by chemical vapor deposition

“…Figure 2 shows cross‐sectional (2(a)) and top (2(b)) views of FE‐SEM images of Ni‐doped TS, prepared by the CVD process using a mixed precursor of Ti(OC 3 H 7 ) 4 + Ni(NO 3 ) 2 . The spherical shape of Ni‐doped TiO 2 particles is similar to a previous study,15 i.e. the as‐prepared layer consisting of a large number of titania particles on a glass substrate.…”

“…These approaches to synthesize various TiO 2 nanomaterials are expected to positively impact realistic applicability. Recently, our study15 proposed an efficient chemical vapor deposition (CVD) approach to fabricate TiO 2 nanosphere (TS) layer on conducting glass, using titanium isopropoxide (Ti(OC 3 H 7 ) 4 as precursor. This approach exhibited the following advantages: (i) atmospheric operation without vacuum equipment; (ii) high growth rate; and (iii) spherical form of TiO 2 products.…”

A facile and large-area fabrication method of superhydrophobic self-cleaning fluorinated polysiloxane/TiO2 nanocomposite coatings with long-term durability

“…15,18 Another is ex situ casting or deposition of superhydrophobic coatings on the substrates. This strategy is versatile for creation of a superhydrophobic surface and can be executed by three routes: (a) creating micro/nanostructure surfaces via deposition of dual-sized particles or nanoparticles and then casting a layer of low surface free energy materials; 20,21 (b) casting low surface free energy coatings and further creating rough structures on the outmost surfaces of the coatings via electron irradiation, 22,23 plasma treatment, 24 nanocasting; 25 (c) casting polymer solutions or polymer/particles (nano)composite solutions and subsequently drying to produce superhydrophobic surfaces by phase separation [26][27][28] or self-organization. [29][30][31][32][33] For outdoor self-cleaning applications, the former two approaches are too complicated and difficult to be realized, while the latter one would be a good choice because it has similar simple fabrication process to the ''traditional organic coatings'' approach.…”

Metal oxide thin films and nanostructures for self-cleaning applications: current status and future prospects

“…Metal oxide thin films for self-cleaning applications can be deposited by a wide variety of techniques such as sol-gel, spray pyrolysis, liquid phase deposition, physical vapor deposition Chemical deposition, hydrothermal methods [101][102][103][104][105][106][107][108][109][110][111][112][113][114][115][116][117][118][119]. In physical and chemical vapour deposition techniques many parameters like pressure, substrate temperature, power density, gas flow rates are available to control properties of films.…”
