Leaf Secret Inspires Self-cleaning PaintA self-cleaning paint inspired by lotus leaves is being developed by Australian researchers. A paint compound is designed to prevent dirt from sticking to its surface.
According to the leader of the researchers, the initial inspiration for the paint came from nature. One researcher noticed that while lotus plants live in water, water never sticks to their leaves, “We asked if we could mimic (模仿) that property.”
Plant leaves keep clean because a thin, and slightly bumpy(隆起), coating of wax(腊膜) on them enables rain to easily wash the dirt from them. The team have mimicked the natural cleaning action of water on leaves by creating a synthetic(化合物) compound, which is designed to decrease the strength of the bond between dirt and the surface of paint.

The idea is yet to undergo a lot of testing. “Testing needs to be done outside and under certain conditions, and under certain temperatures, ” the researchers said.
If it proves itself, the new paint compound is designed to become part of the normal mixture of paint chemicals which include solvent, pigment and oxidants. The paint could be used on house exteriors, cars, road signs and billboards which would then be washed clean any time it rained. It could also make foot surfaces easier to wash.
Answer the following questions.
1.What is the self-cleaning paint?
________________________________
2.How do the researchers get the idea about this kind of paint?
________________________________
3.What is the basis of the new paint?
________________________________
4.What kinds of tests does the paint need?
________________________________
5.Which ways can the paint be used in future?
________________________________
解析:
1. It's a paint compound that can prevent dirt from sticking to its surface. 2. The researchers noticed that while lotus plants live in water ,water never sticks to their leaves. 3. The basis of the new paint is a synthetic compound, which can decrease the strength of the bond between dirt and the surface of paint. 4. Tests outside, under certain condition and under certain temperatures. 5. It can be used on house exteriors, cars, road signs and billboards, etc.
