A process is provided for the incorporation of fibrous material into a polymer wherein the fibrous material as a dispersion in water is added to a solution of the polymer which is being subjected to agitation, whereby the fibrous material transfers from the aqueous phase to the polymer solution...
How To Sew Spandex Fabric Using polyurethane research, DuPont sought to create a new polymer fabric with high elasticity. During the development process, scientists at DuPont referred to this fabric as "spandex;" once this fabric was completed, it was sold under the brand name Lycra, but consu...
If you’ve been trying out different skincare products and want to find out exactly what’s in them, you have a few different options for doing just that. One of the easiest ways to check out the ingredients of a product you bought is to read the list of ingredients on the back of ...
Several nanoparticle systems have been used to aid in the formulation, encapsulation and release of active compounds extracted or derived from natural resources. The main types of these particles are liposomes, solid lipid nanoparticles, inorganic nanoparticles, micro-emulsion, polymer nanoparticles, dendri...
If you live in a particularly dry region, help your soil retain water by using mulch around the base of your plants or adding polymer crystals to your soil mix to store moisture. Managing Pests and Diseases Natural pest control methods (ladybugs, neem oil, etc.) ...
While traditional and thin-film solar panels are made from silicon or similar semiconductors, organic solar cells are made from carbon-based materials. They're often referred to as "plastic solar cells" or "polymer solar cells" for this reason. Organic solar cells are flexible, durable, and ...
A battery connects the positive terminal to the negative terminal through an electrolyte. In a simple laboratory experiment, the electrolyte could be pure water. In a real electrolyzer, performance is improved considerably by using a solid polymer membrane as the electrolyte, which allows ions to mo...
Carbon fiber is a kind of polymer that is sometimes referred to as graphite fiber. It’s a solid material and is extremely lightweight in comparison to its strength. Carbon fiber is incredibly strong—five times stronger than steel and twice as rigid! The best part is, even though it is ...
