ABSTRACT In this study, we synthesized a new organic-inorganic hybrid material based on N-halamine and TiO2 using miniemulsion polymerization. N-halamine as a broad-spectrum antimicrobial agent has a more powerful inactivation ability over other agents. The novel TiO2 based nanocomposites (MPS-TiO2@PVBC-DMH-Cl NPs) demonstrated significantly enhanced UV stability, potent antibacterial and antifungal activities. Upon addition of a certain amount of the nanoparticles into commercial water-based latex paints as UV-stable antibacterial additives, the prepared paint successfully prevented biofilm formation against model microbe cells. The prepared paint was also stable under UV exposure, and readily rechargeable if efficacies were lost under challenging conditions. 相似文献

Water-based coatings require coalescing aids to achieve properties equivalent to solvent-borne paints. A common coalescing
aid in latex paints is 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TMPD-MIB). The relatively large quantity of TMPD-MIB
used in latex paints has raised concerns regarding its emissions to both indoor and outdoor atmospheres. In this study, a
one-dimensional dual (paint and material) layer diffusion model was developed to estimate emissions of TMPD-MIB from two latex
paints applied to gypsum board. The paints contained different pigment volume concentrations (PVC) and different amounts of
TMPD-MIB. Different modeling approaches were used depending on the PVC of the paint. The proposed model for paint drying and
TMPD-MIB emissions was tested with data from previous chamber experiments. Experimental data were first used for purposes
of parameter estimation, and the model was then compared against an independent experimental dataset. The diffusion coefficient
of the paint layer was adjusted as a function of the water content remaining in the wet paint film. The effective diffusion
coefficient of TMPD-MIB in the paint layer was found to be dependent on the PVC and water content of the paint. 相似文献
