A recently published study explores a convenient way to achieve good UV protection for organic pigments coated with titanium dioxide.
overspending polyester (HBP) includes a variety of HBPs. Generation 2 (HBPs16) and 4th generation (HBPs 64) are designed to encapsulate the pigments and
. The pigment encumulation of titanium dioxide is then coated from the positive butanol (TBOT) method by sol-gel. The coating properties of titanium dioxide are described through thermal heavy analysis (TGA), scanning/transmission electron microscopy (SEM / TEM), Fourier Transform Infrared Spectroscopy (FTIR), Dynamic Light Scattering (DLS), X-ray diffraction map (XRD) and Zeta position analysis.
significant improvement in UV protection
stable coating pigment nanocomposates for printing cellulose fabrics. The UV shielding performance of pigment printing is systematically studied. It is further proved that the titanium dioxide shell of the pigment print obtained can be used as an effective protection against UV light and can significantly enhance UV shielding performance. The degree of protection depends on the number of hydroxyl ends in overspending polyester. In addition, under adverse conditions, titanium dioxide coated pigments have no significant effect on the driving force that accelerates the pigment printing process.
the study was published in Organic Coatings Progress Volume 136, November 2019, 105295.
