fine fibers made from polymer crosslinked with

Fiber

Fiber or fibre (from Latin: fibra) is a natural or man-made substance that is significantly longer than it is wide Fibers are often used in the manufacture of other materials The strongest engineering materials often incorporate fibers for example carbon fiber and ultra-high-molecular-weight polyethylene

Elastomeric Fibers

Elastomeric fibers are those fibers that possess extremely high elongations at break and that recover fully and rapidly from high elongations up to their breaking point The fibers are all used in specialized applications where high elasticity is necessary within the textile structure An Elastomer is a polymer with the physical property of elasticity The elastomer is a term derived from elastic polymer which is often

Cellulose hydrogels physically crosslinked by glycine

Crosslinking in polymer chemistry leads to a multidimensional extension of polymeric chains which results as a network structure It can be classified as ionic (physical) or covalent (chemical) When a polymer is in liquid form it can turn into a "solid" or "gel" due to the chain crosslinking Great attention is paid to crosslinked polymers as they are relatively resistant to heat wear and solvents in addition to being

A fiber is obtainable from or comprises an ethylene/alpha-olefin interpolymer characterized by an elastic recovery Re in percent at 300 percent strain and (1) cycle and a density d in grams/cubic centimeter wherein the elastic recovery and the density satisfy the following relationship: Re1481-1629(d) Such interpolymer can also be characterized by other properties The fibers made

POLYMERS AND PLASTICS

Polymers can also be classified in other ways for example based on their uses many varieties of rubber are often referred to as elastomers Dacron is a fiber and polyvinyl acetate is an adhesive The chemical based classification will be used in this essay ADDITION POLYMERS Most of the polymers made are of the addition type The monomers

Polymers

The synthesis and photoluminescence properties of crystal crosslinked gels (CCGs) with an aggregation-induced emission (AIE) active crosslinker derived from tetraphenylethene (TPE) is discussed in this article The CCG was prepared from a metal organic framework (MOF) with large pore aperture to allow the penetration of TPE crosslinker The obtained CCG possessed a rectangular shape originated
