Abstract

UV-LED curable coatings represent an up-to-date attractive field due to the high curing efficiency even in the presence of high filler loadings, as well as to the absence of infrared wavelengths that may negatively impact on heat-sensitive substrates. The addition of carbonaceous materials, such as biochar (BC) and/or multiwalled carbon nanotubes (MWCNTs) could positively improve both the rheological and thermal properties. In this study we report on the synthesis and characterization of carbon-reinforced films containing nanometric (MWCNTs) and micrometric (BC) carbon-based materials. We analyze the rheological properties of the UV-LED curable dispersions, as well as the thermal and optical properties of the resulting films, establishing some correlations between filler dispersion/loading with the main observed properties.

摘要

紫外光发光二极管（UV-LED）可固化涂料是一个具有吸引力的前沿领域，这是因为即使存在高填充量，其固化效率依然很高，而且不存在可能会对热敏基材产生负面影响的红外波长。添加含碳材料，如生物炭（BC）和/或多壁碳纳米管（MWCNT），可以积极改善流变学和热性能。在本研究中，我们报告了含有纳米级（MWCNT）和微米级（BC）碳基材料的碳增强薄膜的合成与表征。我们分析了UV-LED可固化分散体的流变学性质，以及所得薄膜的热学和光学性质，建立了填料分散/负载量与主要观察到的性质之间的一些相关性。
