研究目的
Investigating the stability of silver nanowire/polyimide composite films for transparent film heaters under ambient conditions.
研究成果
The cPAP films demonstrated superior stability under accelerated test and H2S atmosphere conditions compared to cPA films, with minimal impact on transmittance, mechanical flexibility, and heating performance. The fabricated TFHs show potential for applications in defogging or defrosting smart windows.
研究不足
The study focuses on the stability of AgNW/polyimide composite films under specific conditions (105 °C and 100% relative humidity, and H2S atmosphere). The long-term stability under more varied environmental conditions and the scalability of the fabrication process are areas for further investigation.
1：Experimental Design and Method Selection:
The study employed a simple drop-coating approach to fabricate transparent film heaters (TFHs) by embedding silver nanowires (AgNWs) between colorless polyimide (cPI) and polymethyl methacrylate (PMMA).
2：Sample Selection and Data Sources:
AgNWs ink was purchased from Ningbo Nanotech Advanced Materials Co., Ltd. The cPI in N,N-dimethylacetamide (DMAC) solution and PMMA powder dissolved in chloroform were prepared.
3：List of Experimental Equipment and Materials:
Equipment included a roll coater, SEM (Hitachi S-4800), digital multimeter (FLUKE 15B), UV–Vis spectrophotometer (Perkin-Elmer Lambda 950), power source (LODESTAR DC POWER SUPPLY LPS305D), infrared thermometer (SMART SENSOR AR842A), and infrared camera (FLUKE TiS20 or FLIR E60).
4：0). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: AgNWs suspension was deposited on a glass substrate, annealed, coated with cPI solution, and then PMMA solution was drop-coated onto the cPA film.
5：Data Analysis Methods:
The resistance change ratio (Rc) was defined and calculated to evaluate the stability of the films under various conditions.
