Photosensitive materials have their chemistry changed by light. The most energetic light is that pesky short wavelength ultraviolet or UV light. It tends to take weak covalent bonds apart if it can. Any material with weak covalent bonding may be subject to photodegradation. There are any number of materials - or components of materials - that fall into this group. As a group, the polymers, plastics composed of long chain molecules, have a number of different flavors that can get hammered by UV radiation. Many plastics will stand up to sunlight (specifically the UV) fairly well, and automotive paint is just one of them. And pollution (particularly oceanic polution) by plastics is reaching monumental proportions because the materials hang around so long. But as a group, the polymers take a beating when the energy in the UV rays that pound the material break chemical bonds and destroy the integrity of the material. We've seen what sun does to a plastic grocery bag. The most photosensitive materials are photographic films. But they are designed to do what they do in the specific way that they do it. They could easily be classified as the material most sensitive to photodegradation.
A material known for its ability to absorb water is called a hydrophilic material. Examples include cotton, paper, and certain types of polymers.
There are two main types of etching: Chemical etching, where a chemical solution is used to dissolve the material and create the desired design or pattern. Mechanical etching, which involves physically removing material through methods like engraving or sandblasting.
properties of matter
A material through which water can readily flow is called permeable material. This type of material allows water to pass through easily due to its interconnected pore spaces. Examples include sand, gravel, and certain types of soil.
Materials that are biocompatible and commonly used in medical devices, such as titanium, stainless steel, and some types of silicone, are less likely to be rejected by the body. It's best to consult with a healthcare professional or surgeon to determine the most suitable material for your specific situation.
The definition of photodegrade is of a substance to be decomposed by the action of light. It means to breakdown when exposed to sunlight and is a type of chemical change that results from light being absorbed.

Three types of material that can be recycled are paper, glass, and plastic. Another one is cardboard.

material scientists are scientists who work with different types of materials to cate new ones
The two types of conductivity are electrical conductivity, which refers to the ability of a material to conduct electricity, and thermal conductivity, which refers to the ability of a material to conduct heat.
The types of decay are different because every material has its own nucleus unstability
The different types of materials used for screen frame material include aluminum, fiberglass, and vinyl. Each material has its own advantages and disadvantages in terms of durability, cost, and maintenance.
