Reducing the amount of energy consumed to run products and services remains one of the most important topics being addressed in the modern world as advanced products and services tend to require more energy to perform sophisticated functions with higher level of complexity. However, new technology advancement and discovery will not be sustainable with the continuous exploitation of non-renewable energy that leads concerning environmental problems. One way to reduce the consumption of energy inside buildings or vehicles is to implement smart glasses that block infrared radiation from penetrating. In this report, student synthesizes different silver nanostructures that include wires and particles, and subsequently coats them onto glass substrate using dip coating technique and sol-gel as precursor. Substrates are coated with different concentration of AgNWs in ethanol by weight percentage to study the effect on physical, optical and electrical properties. Various characterizations methods are used on both silver nanostructures and coated films to allow visual inspection and performance evaluation. All experiments and results are detailed with figures and explanations. Last but not the least, student summarizes the results of his findings and gives recommendation on potential improvement.
