Also, the optimum range of concentration of GO and TiO 2 nanoparticles in polyelectrolyte solutions was determined to fabricate the film with the combined features of self-healable, UV-blocking, and anti-fog. The effect of the concentration of GO and TiO 2 nanoparticles on self-healing and UV-protection properties were investigated.
Due to the hydrophilic feature of PDDA/PAA molecules, the film also showed the anti-fog property in different environmental conditions. An effective UV-block performance was incorporated into the film by using the graphene oxide (GO) and titanium dioxide (TiO 2) nanoparticles as UV-blocking additives. When scratches occur, the film shows a quick and durable self-healing capability due to the dynamic movement of the flexible polyelectrolyte complex chains at the edges of the scratches.
The SSA-LbL method was found to be more efficient and time-saver in making a homogeneous thick film in tens of micrometers, compared to the conventional immersive assembly method which makes thin films in the nanometer range. Bloomberg Businessweek helps global leaders stay ahead with insights and in-depth analysis on the people, companies, events, and trends shaping todays. Herein, a high-performance and multifunctional LbL film was fabricated by using a spin-spray-assisted (SSA-LbL) assembly method with poly(diallyldimethylammonium chloride) (PDDA) and poly(acrylic acid) (PAA).
Layer-by-layer (LbL) deposition of oppositely charged polyelectrolytes has been widely used to make responsive and multifunctional smart films. Browse 15,788 images of letter r stock photos and images available, or start a new search to explore more stock photos and images.
