Superabsorbent polymer

Diaper Debate When my wife and I were expecting, we made a list of all the items that should be purchased before the baby arrived. The one item every one of our friends and relatives said we could not have enough of was diapers. We started early on by pricing plain, standard, and no frills disposable diapers. These were the diapers I knew and assumed were the only option for an on-the-go family like ours. I slowly noticed other families with new babies and trends among them. Not all babies were wearing regular disposable diapers, but something fluffy with cool designs. When I asked my wife what this strange contraption was, she explained it as a cloth diaper. This was not the cloth diaper I had seen in old television shows and cartoons, it was a fashionable clothing item with a purpose. Once I realized this new approach to an old method was available, I decided to do some research. My findings on the design, safety, environmental impact and overall brought me to one conclusion; cloth diapers were the better choice. Though I do not have an eye for fashion, I know that cool designs are better than no design. The average disposable diaper is plain and white. For something that catches waste it would not seem that this would be a problem. However, this seemingly insignificant detail does matter to some. A plain diaper can look dull or out of place in professional baby portraits, or poking out from under a newly mobile baby 's dress. Disposable diapers are now being made with…

Sodium polyacrylate is a polymer with a unique structure, that chemists are leveraging in a variety of lucrative industrial applications. Sodium polyacrylate possesses a unique chemical property: the ability to absorb incredible amounts of water. It can absorb 300 to 800 times its weight in water (Superabsorbent Polymers). Industrial chemists have taken advantage of the polymer’s special function, and have incorporated it into dozens of different products. In fact, the industry behind…

Plastics are a material currently being used all around the world. As the production of this synthetic polymer has increased, it has become almost impossible to completely avoid interaction with a plastic material. With the discovery of this practical material, positives and negatives were discovered too. Plastics have a strong effect on the environment and human health. During manufacturing, additives are put in that can be harmful to each of these important aspects. Due to their synthetic…

and “unsinkability”. When the U.S Coast Guard adopted for use in a six-man life raft, was the start of many other wartime applications by the Coast Guard and U.S Navy. This new material was light weight but as durable as others, and exhibited outstanding thermal and moisture-resistant properties. INVENTION OF STYROFOAM A German apothecary named Edward Simon discovered polystyrene in 1939. He isolated the substance from…

6.3. A. Microemulsions (135-143) Microemulsions are clear, stable, isotropic mixtures of oil, water, and surfactant, frequently in combination with a cosurfactant 135-137. Microemulsions have several advantages such as enhanced drug solubility, good thermodynamic stability, and higher transdermal permeability over conventional formulations 138,139. Many studies reported the use of microemulsions as topical drug delivery vehicles showed their ability to improve transdermal and dermal delivery…

According to cerakoteguncoatings.com (2017), Cerakote is a Polymer-Ceramic coating that can be applied to metals, plastics, polymers and wood. Cerakote is used on; knives, weapons, tools, some electronic covers, glasses and anything durable that needs a tough coating. This ceramic thin-film coating is intended to offer an appealing finish with unequaled performance. The ceramic coating of Cerakote provides the advantage of having extraordinary; adhesiveness, pliability, corrosion and wear…

The polyurethane segments show high intersegment attraction such as hydrogen bonding and may be able to crystallize and form hard segments. In such polymers hard segments with Tg well above normal ambient temperature are separated by polyol soft segments, which in the mass are rubbery in nature. Hard and soft segments are arranged alternate along the polymer chain. Fig.7. Polyurethane chain configuration [32] 4.2.2. Polyurethane properties and advantages for product development…

Before we can talk about what a polymer is, we need to know about ATOMS and ELEMENTS and MOLECULES. To learn about atoms and elements and molecules, click here. Paul Lemur This is PAUL LEMUR. He's a lemur named Paul. Polymers are made up of many many molecules all strung together to form really long chains (and sometimes more complicated structures, too). What makes polymers so fun is that how they act depends on what kinds of molecules they're made up of and how they're put together. The…

How this fact neoprene? The wetsuit is made by a set of fabrics neoprene (it is a type of synthetic rubber with micro bubbles) that sewed or sealed to each other whose task is to try to prevent the passage of water or heat loss when one is wearing. Today the technology advanced a lot and we almost waterproof neoprene. Who invented the wetsuit? But this was not always so. The first sketches that were found on something like a neoprene date from the time of Leonardo da Vinci. Much later, Hugh…

Similar method was used for the synthesis of the poly(4-(4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b ']dithiophen-2-yl)-8-(5-(2,6-didodecylbenzo[1,2-d:4,5-d ']bis(thiazole)-4-yl)selenophen-2-yl)-2,6-didodecylbenzo[1,2-d:4,5-d ']bis(thiazole)) [P2] polymer by replacing the 2,5-bis(trimethylstannyl)thiophene with 2,5-bis(trimethylstannyl)selenophene, as shown in Fig. 1. The number-average molecular weights (Mn) of P1 and P2 were 15,710 and 26,220, with polydispersity indexes (PDI) Đ of…
