In recent years, the introduction and use of new nanomaterials in construction has increased at a rapid rate. Exterior surface paints have been a product that have had these nanomaterials added to them. In this study, the effects of natural weathering and exposure to atmospheric agents was examined to determine the detrimental effects on outdoor paint that has been created with nanomaterials. Data collected over the course of the yearlong study indicate that the nanoparticles of the titanium dioxide were eliminated rapidly. Further testing indicated that various elements of weathering were affecting the physical integrity of the paint. The weathering agents that appeared to have the greatest effect on the samples were acid deposition and total precipitation. There was a strong association between carbon monoxide and the effects on the panels. These results can lead to new plans for assessments involving the synergistic effects of all weathering agents.
近年来，新型纳米材料在建筑中的引入和使用呈快速增长趋势。外墙涂料就是添加了这些纳米材料的产品。在这项研究中，研究了自然风化和大气物质暴露对使用纳米材料的户外涂料的有害影响。经过一年的研究收集的数据表明，纳米二氧化钛颗粒迅速被消除。进一步的测试表明，各种风化因素影响了涂料的物理完整性。对样品影响最大的风化因素似乎是酸沉降和总降水量。一氧化碳与面板的影响之间存在很强的关联性。这些结果可以为评估所有风化因素的协同效应提供新的计划。
