Summary
Trimethylsilane (TMS) plasma nanocoatings significantly enhance the stability of silver nanowires (AgNWs). These protective coatings improve conductivity retention against environmental and aqueous degradation, crucial for electronics applications.
Area of Science:
- Materials Science
- Nanotechnology
- Surface Chemistry
Background:
- Silver nanowires (AgNWs) are essential for transparent conductive films.
- AgNWs suffer from environmental degradation, limiting their long-term stability.
- Developing effective protective strategies for AgNWs is critical for advanced electronics.
Purpose of the Study:
- To assess the efficacy of trimethylsilane (TMS) plasma nanocoatings in protecting AgNWs.
- To evaluate the impact of nanocoating thickness on AgNW stability.
- To investigate the effect of TMS nanocoatings on AgNW electrical and surface properties.
Main Methods:
- Deposition of TMS plasma nanocoatings of varying thicknesses onto AgNWs.
- AgNWs were prepared on glass, SEBS, and PLLA substrates.
- Electrical resistance and surface properties were measured after environmental and aqueous exposure.
Main Results:
- TMS nanocoatings minimally increased AgNW electrical resistance (~25%).
- Coated AgNWs showed significantly improved stability against degradation in ambient and PBS conditions.
- Increased nanocoating thickness further enhanced conductivity stability and surface hydrophobicity.
Conclusions:
- TMS plasma nanocoatings offer robust protection for AgNWs against degradation.
- These nanocoatings preserve electrical conductivity and optical transparency.
- TMS nanocoatings are promising for enhancing the durability of AgNWs in transparent electrodes and wearable devices.
