Abstract

Silver (Ag) ornamented TiO semiconducting nanoparticles were synthesized through the sol-gel process to be utilized as nanofillers with photo resin to enhance the mechanical and thermal properties of stereolithography 3D printed objects. The as-prepared Ag-TiO nanoparticles (Ag-TNP) were typified and qualified by XRD, XPS, Raman, and FESEM; TEM analysis dissected the morphologies. The enhancement in the tensile and flexural strengths of SLR/Ag-TNP nanocomposites was noted as 60.8% and 71.8%, respectively, at the loading content of 1.0% / Ag-TNP within the SLR (stereolithography resin) matrix. Similarly, the thermal conductivity and thermal stability were observed as higher for SLR/Ag-TNP nanocomposites, equated to neat SLR. The nanoindentation investigation shows an excerpt hike in reduced modulus and hardness by the inclusion of Ag-TNP. The resulted thermal analysis discloses that the introduction of Ag-TNP can appreciably augment the glass transition temperature (T), and residual char yield of SLR nanocomposites remarkably. Hence, the significant incorporation of as-prepared Ag-TNP can act as effective nanofillers to enhance the thermal and mechanical properties of photo resin.

摘要

通过溶胶-凝胶法合成了银（Ag）修饰的TiO半导体纳米颗粒，用作光固化树脂的纳米填料，以提高立体光刻3D打印物体的机械性能和热性能。通过XRD、XPS、拉曼光谱和场发射扫描电子显微镜对制备的Ag-TiO纳米颗粒（Ag-TNP）进行了表征和鉴定；透射电子显微镜分析了其形态。在立体光刻树脂（SLR）基体中，当Ag-TNP的负载量为1.0%时，SLR/Ag-TNP纳米复合材料的拉伸强度和弯曲强度分别提高了60.8%和71.8%。同样，与纯SLR相比，SLR/Ag-TNP纳米复合材料的热导率和热稳定性更高。纳米压痕研究表明，加入Ag-TNP后，降低模量和硬度有显著提高。热分析结果表明，Ag-TNP的引入可以显著提高SLR纳米复合材料的玻璃化转变温度（T）和残炭率。因此，所制备的Ag-TNP的显著掺入可以作为有效的纳米填料来提高光固化树脂的热性能和机械性能。
