UV-curable polymer composites are of importance in industry, biomedical applications, scientific fields, and daily life. Outstanding physical properties of polymer composites were achieved with nanoparticles as filler, primarily in enhancing mechanical strength or barrier properties. Structure-property relationships of the resulting nanocomposites are dictated by the polymer-filler molecular architecture, i.e. interactions between polymer matrix and filler, and high surface area to volume ratio of the filler particles. Among monomers, acrylates and methacrylates attracted wide attention due to their ease of polymerization and excellent physicochemical and mechanical properties of the derived polymers. We prepared and photopolymerized two series of formulations containing hydrophobized silica nanofiller (Aerosil R7200) dispersed in 2-hydroxyethyl acrylate (HEA) or polyethylene glycol diacrylate (PEGDA) monomers. We compared selected physical properties of the formulations, both before and after photocuring; specifically the viscosity of formulations and dispersion of the filler in the polymer matrices. Additionally, we estimated the bulk Poisson׳s ratio of the investigated nanocomposites. This article contains data related to the research article entitled "Nanoscale Young׳s modulus and surface morphology in photocurable polyacrylate/nanosilica composites" (Gojzewski et al., 2017) [1].
紫外光固化聚合物复合材料在工业、生物医学应用、科学领域及日常生活中都很重要。以纳米粒子作为填料可使聚合物复合材料具有出色的物理性能，主要体现在提高机械强度或阻隔性能方面。所得纳米复合材料的结构-性能关系取决于聚合物-填料分子结构，即聚合物基体与填料之间的相互作用以及填料颗粒的高比表面积。在单体中，丙烯酸酯和甲基丙烯酸酯因其易于聚合以及衍生聚合物具有优异的物理化学和机械性能而备受关注。我们制备并光聚合了两个系列的配方，其中包含分散在丙烯酸羟乙酯（HEA）或聚乙二醇二丙烯酸酯（PEGDA）单体中的疏水化二氧化硅纳米填料（气相二氧化硅R7200）。我们比较了光固化前后配方的选定物理性能；具体而言，是配方的粘度以及填料在聚合物基体中的分散情况。此外，我们还估算了所研究纳米复合材料的体积泊松比。本文包含与题为《光固化聚丙烯酸酯/纳米二氧化硅复合材料的纳米级杨氏模量和表面形态》（戈耶夫斯基等人，2017年）[1]的研究论文相关的数据。
