This contribution introduces a new technique for preparing reversible thermochromic polydiacetylene/zinc(II)/zinc oxide nanocomposites in ambient conditions. The new solution-mixing method involves simple mixing of all precursors in liquid phase, followed by an incubation at room temperature, resulting in nano composites with small particle size around 60 nm. Important experimental parameters were investigated, and the new method requires shorter processing time and lesser energy compared to conventional techniques, crucial for large-scale production.
This contribution introduces a new technique for preparing reversible thermochromic polydiacetylene /zinc(II)/zinc oxide nanocomposites in ambient conditions. Our new solution-mixing method involves simple mixing of all precursors in liquid phase, followed by an incubation at room temperature. The particle size of resultant nano composites is quite small, similar to 60 nm. The small-size characteristic promotes their sensitivity to acid/base. Important experimental parameters, including aging time, incubating temperature, and type of solvents, were investigated. Compared to conventional techniques, our new method requires much shorter processing time and lesser energy, important for large-scale production.
