This study explores task-specific ionic liquids (TSILs) in smart floor systems, highlighting their strong electrical rectification abilities and previously established wood preservative properties. Two types of TSILs, featuring a "sweet" anion and a terpene-based cation, were used to treat selected wood samples, allowing for a comparison of their physical and electrical performance with untreated and commercially treated counterparts. Drop shape analysis and scanning electron microscopy were employed to evaluate the surface treatment before and after coating. Near-IR was used to confirm the presence of a surface modifier, and thermogravimetric analysis (TGA) was utilized to assess the thermal features of the treated samples. The different surface treatments resulted in varied triboelectric nanogenerator (TENG) parameters, with the molecular structure and size of the side chains being the key determining factors. The best results were achieved with TSILs, with the instantaneous voltage increasing by approximately five times and the highest voltage reaching 300 V under enhanced loading. This work provides fresh insights into the potential application spectrum of TSILs and opens up new avenues for directly utilizing tested ionic compounds in construction systems.
本研究探索了智能地板系统中的特定任务离子液体（TSILs），突出了它们强大的电整流能力以及先前已确定的木材防腐性能。使用了两种具有“甜味”阴离子和萜烯基阳离子的TSILs来处理选定的木材样本，以便将其物理和电气性能与未处理的以及商业处理的同类样本进行比较。采用液滴形状分析和扫描电子显微镜来评估涂层前后的表面处理情况。利用近红外光谱确认表面改性剂的存在，并采用热重分析（TGA）来评估处理后样本的热特性。不同的表面处理导致了摩擦纳米发电机（TENG）参数的变化，其中侧链的分子结构和大小是关键决定因素。TSILs取得了最佳结果，在增强负载下瞬时电压增加了约五倍，最高电压达到300V。这项工作为TSILs的潜在应用范围提供了新的见解，并为在建筑系统中直接利用经过测试的离子化合物开辟了新途径。
