Preparation of SiO₂/polymer co-coated colored aluminum pigments with excellent corrosion resistance and UV protection and their application in fabrics

Antibacterial and ultraviolet protective neodymium-doped TiO2 film coated on polypropylene nonwoven fabric via a sputtering method

“…A larger K/S value implies a darker color. 43 On the contrary, a smaller K/S value implies a lighter color. Therefore, the K/S value is used to express the color depth of the fabric surface because there is a linear relationship between K/S and gloss.…”

Preparation of Quaternary Ammonium Separation Material based on Coupling Agent Chloromethyl Trimethoxysilane (KH-150) and Its Adsorption and Separation Properties in Studies of Th(IV)

“…For SG-CTSQ, in Figure 3c 1 , due to the introduction of a large amount of octyl (containing −CH 3 and −CH 2 −) on the surface of silica gel after the quaternization reaction, the in-plane bending vibration peak of C−H in −CH 3 was more obvious at 1416 cm −1 and the out-of-plane bending vibration peak of C−H in −CH 3 appeared at 1156 cm −1 , which was previously covered by the large peak of 1078 cm −1 [29]. The in-plane bending vibration peak at 1376 cm −1 is of C−H in −CH 2 −.…”

“…Molecules 2022, 26, x FOR PEER REVIEW 5 of 24 in-plane bending vibration peak of C−H in −CH3 was more obvious at 1416 cm −1 and the out-of-plane bending vibration peak of C−H in −CH3 appeared at 1156 cm −1 , which was previously covered by the large peak of 1078 cm −1 [29]. The in-plane bending vibration peak at 1376 cm −1 is of C−H in −CH2−.…”

“…The above analysis shows that trioctylamine was successfully present on the surface of the silica gel and quaternized with coupling agent molecules. The 29 Si-MAS NMR spectra of SG and SG-CTS are shown in Figure 4. For SG, in Figure 4a, −90.0 ppm is the absorption peak of Si corresponding to the double-base −OH, −100.0 ppm is the absorption peak of Si corresponding to free-type −OH and hydrogen-bonded −OH, and −111.6 ppm is absorption peak of Si corresponding to siloxane groups [31].…”
