Abstract

In the present study, chemically surface-treated nanoparticles and nanofibers were added to the adhesive to improve the performance of the two-component structural adhesive. In the study, DP460 structural adhesive was used as adhesive, functionalized Multi Walled Carbon Nanotubes (MWCNT-COOH) with COOH and carbon fiber (CF) chemically surface treated with HNO3 solution were used as nanostructures. In the experimental study, eight different parameters were investigated as the nanostructure was (i) undoped, (ii) 1 wt% MWCNT-COOH added, (iii) 1wt%. untreated CF added, (iv) 0.5 wt% chemically treated CF added, (v) 1 wt% chemically treated CF added, (vi) 2 wt% chemically treated CF added, (vii) 0.5 wt% MWCNT-COOH and 0.5 wt% chemically treated CF added, and (viii) 1 wt% MWCNT-COOH and 1wt% chemically treated CF added. According to the results of the study, adding nanoparticles to the adhesive increases the performance of the adhesive by about 12%, while adding nanofibers increases the performance of the adhesive by about 18%. In addition, increasing the inertness and wettability of nanofibers by chemical treatment, as well as the use of nanoparticles and fibers together, significantly increases the performance of the adhesive. In addition, the obtained results were supported by fourier transform infrared spectroscopy (FT-IR) analysis and scanning electron microscopic (SEM) analysis.

化学氧化过程对含有纳米颗粒和纳米纤维添加剂的双组分胶粘剂性能的影响

在本研究中，粘合剂中添加了经过化学表面处理的纳米颗粒和纳米纤维，以改善双组分结构粘合剂的性能。本研究使用 DP460 结构粘合剂作为粘合剂，使用 COOH 功能化多壁碳纳米管（MWCNT-COOH）和经 HNO3 溶液化学表面处理的碳纤维（CF）作为纳米结构。在实验研究中，研究了八种不同参数的纳米结构：(i) 未掺杂；(ii) 添加 1 wt% 的 MWCNT-COOH；(iii) 添加 1 wt% 的未处理 CF；(iv) 0.5 wt% 的化学处理 CF，(v) 1 wt% 的化学处理 CF，(vi) 2 wt% 的化学处理 CF，(vii) 0.5 wt% 的 MWCNT-COOH 和 0.5 wt% 的化学处理 CF，以及 (viii) 1 wt% 的 MWCNT-COOH 和 1 wt% 的化学处理 CF。研究结果表明，在粘合剂中添加纳米粒子可使粘合剂的性能提高约 12%，而添加纳米纤维可使粘合剂的性能提高约 18%。此外，通过化学处理提高纳米纤维的惰性和润湿性，以及同时使用纳米颗粒和纤维，都能显著提高粘合剂的性能。此外，傅立叶变换红外光谱（FT-IR）分析和扫描电子显微镜（SEM）分析也支持所获得的结果。
