Synthesis and characterization of TiO2/fluorocopolymer nanocomposites with core-shell structure

Preparation, thermostability, and hydrophobic properties ofTiO2/poly(dodecafluoroheptyl methacrylate) nanocomposites

“…TGA was used to study the graft ratio of fluoropolymer and thermal stability of nanocomposites, and the results are shown in Figure . In Figure (a), the thermal weight loss of nano‐TiO 2 is 1.6% because of the decomposition of some hydroxyl on TiO 2 surface . The decomposition of MPS led to the thermal weight loss of 5.8%.…”

“…It is seen that some needle‐like peaks can be observed at the film surface, as nano‐TiO 2 content is increased from 10 wt % to 40 wt %, more apparently needle‐like peaks can be found. This phenomenon means that the surface roughness of the nanocomposite films is enhanced significantly with the increment of nano‐TiO 2 content, deriving from the existence of free TiO 2 particles on the film surface, which is in agreement with the results reported in previous literatures …”

“…In Figure 6(a), the thermal weight loss of nano-TiO 2 is 1.6% because of the decomposition of some hydroxyl on TiO 2 surface. 31 The decomposition of MPS led to the thermal weight loss of 5.8%. As a result, MPS graft ratio on TiO 2 surface is 4.2%, which is calculated by W MPS (%) 5 (weight loss of MPS -TiO 2 ) -(weight loss of TiO 2 ).…”

Retracted: A novel composite coating to improve the environmental adaptability of combustible cartridges

“…Fluoropolymer‐inorganic nanocomposites not only have good physical properties, such as high hardness and high strength of inorganic materials, but also have low surface free energy and thermal stability of fluoropolymer materials . At the same time, fluorine‐containing composites have been used to prepare super‐hydrophobic surfaces , which provides a method to address the problem of water absorption of combustible cartridges. Therefore, the addition of fluoropolymer to the nitrocellulose varnish can solve the problem of poor wear resistance and flammability of the initial nitrocellulose coating, and it is more significant in improving the adaptability of the combustible cartridge.…”

Design and fabrication of a composite coating to improve the environmental adaptability of combustible cartridges

“…Fluoropolymer-inorganic nanocomposites [9][10][11][12] not only have good physical properties, such as high hardness and high strength of inorganic materials, but also have low surface free energy [13][14][15] and thermal stability of fluoropolymer materials [16][17][18][19]. At the same time, fluorine-containing composites have been used to prepare super-hydrophobic surfaces [20][21][22][23], which provides a method to address the problem of water absorption of combustible cartridges. For example, Chen [24] reported the spin-coated fluorosilane functionalized silica nanoparticles to prepare superhydrophobic surfaces.…”
