Improving the quality and design of plastic so that we pull its polymers – the long chains of molecules that make it up – apart and put them back together in an endless loop would mean that plastic would be made once a...
Like other polymers, spandex is made from repeating chains of monomers that are held together with an acid. Early in the spandex development process, it was recognized that this material is highly heat-resistant, which means that notoriously heat-sensitive fabrics like nylon and polyester are impro...
Homemade slime is a fun way to explore chemistry concepts like polymers, cross-linking, states of matter, elasticity, and viscosity! When borate ions (from activators like sodium borate, borax powder, or boric acid) mix with PVA glue (polyvinyl acetate), a cross-linking chemical reaction occur...
The first key to success is making sure you have the right tools. That means having the right 3D printer and accessories. With polypropylene, only a couple of upgrades are recommended if they do not already come stock with your machine. FDM printers that have the electrical hardware to print...
How firm do you like your slime? 💡 BAKING SODA SLIME TIP: Slime with clear glue usually doesn’t need quite as much baking soda as slime with white glue! 2. Slime Activator The saline solution is the slime activator and helps the slime to get its rubbery texture! Be careful; adding...
Because of this highly decisive factor in the valuing of this type of jade stone, some will treat or bleach jade in order to obscure and remove the evidence of discoloration before instilling it with colored polymers; these artificially altered jadeites are not nearly as valuable as their ...
Temperature isone of the most important settings to fine tune when printing. It generally depends on thematerial to 3D print. Theextrusion temperature for printing polymersmust be higher than the Tm, the melting temperature, to have a fluid material that can rearrange...
Polymer chemistry studies the synthesis, properties, and applications of polymers. Polymers are large molecules of repeating subunits widely used in industries such as plastics, textiles, and biomedicine. Biodegradable polymers: synthesis and environmental impact Polymers in tissue engineering and regenerative...
You add the borate ions to the mixture, and it then starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubbery like slime! Slime is a polymer. Picture the difference between wet spaghetti...
These inorganic polymers are unique materials being used in personal care applications for more than half a century due to their distinctive properties. The resultant of the strength of the Si-O bound is a chemical with high thermal and biological stability. Their low surface tension conjugated ...
