Identify 2 composites that are photoresponsive and answer the following: What is the primary parent material? What is the limitation in using the parent material? What material has properties that will help reduce or eliminate the limitation of the parent material? How do the composite properties differ from those of the parent material? A sample answer would look like this: Primary parent material: titanium dioxide (TiO2) Limitation in using parent material: it absorbs only in the UV (4-5% of solar spectrum) Materials that will reduce/eliminate limitation: Chalcogenides (cadmium sulfide or CdS) absorbs in visible part of solar spectrum Difference in composite and parent: a TiO_2-CdS composite will be able to absorb both UV and visible spectrum resulting in improved optical properties
