To be hydrophobic means to fear water. In chemistry, it refers to the property of a substance to repel water.It isn't that the substance is repelled by water so much as it has a lack of attraction to it.
Examples of hydrophobic substances include fats, oils, waxes, alkanes and other greasy substances. The term hydrophobic comes from the Greek and is translated as “having a horror of water” or “water fearing.” In other words, hydrophobicity is a property of a substance that repels water.
Hydrophobic literally means “the fear of water”. Hydrophobic molecules and surfaces repel water. Hydrophobic liquids, such as oil, will separate from water. Hydrophobic molecules are usually nonpolar, meaning the atoms that make the molecule do not produce a static electric field. In polar molecules these opposite regions of electrical ...
Examples of Hydrophobic Molecules and Materials Waxes For example, if you have ever had your car waxed, you probably noticed that the water would bead up and roll off of the paint afterwards.
Proteins are large structures that use the effects of hydrophobic and hydrophilic groups to help them take shape. Another, simpler, example is the Phospholipid found in the bilayer making up the ...
The shape of a surface can also amplify the effects: For example, if a material is hydrophobic, creating nanopatterns on its surface can increase the contact area with a droplet, amplifying the effect and making the surface superhydrophobic. Similarly, nanopatterning of a hydrophilic surface can make it superhydrophilic.
Examples of Hydrophilic Sugar. Sugar, or more specifically glucose, is a molecule that many types of cells use as an energy source. A molecule of glucose has both hydrophobic and hydrophilic portions. The picture below shows a molecule of glucose. The black balls are carbon atoms, the red balls are oxygen atoms, and the white balls are hydrogen ...
All of the other answers use lots of words but no pictures. I thought I’d do the opposite, using as many pictures as possible to explain hydrophilic, hydrophobic, ultrahydrophobic, ultrahydrophilic, and amphipathic. Source: What is meant by hydrop...
Hydrophobic is water hating, hydrophilic is water loving. ie, hydrophobic substances avoid water, hydrophilic are attracted Asked in Biology , Chemistry , Biochemistry
For example, the super-hydrophobic coatings on 316L stainless steel exhibit an excellent corrosion resistance in chloride-containing solution at room temperature. Corrosion can be protected by making the surface hydrophobic, it is found hydrophobic surfaces strongly decrease the corrosion rate of concrete surface.
