CONSTITUTION:A composition obtained by compounding preferably a poly(m- phenyleneisophthalamide) polymer, an amide solvent such as N,N-dimethyl-acetamide, and a solubilization assistant composed of calcium chloride, is introduced into a multi-stage aqueous coagulation bath through the T-die of an ...
poly(m-phenyleneisophthalamiderheological propertiessolutionionic liquidThe steady-state rheological properties of poly ( m -phenyleneisophthalamide)(PMIA) in 1- n -butyl-3-methylimidazolium chloride [Bmim]Cl and DMAc/LiCl solutions are presented. The polymer in the concentration range investigated ...
The aromatic poly( m-phenylene isophthalamide)( PMIA) hollow fiber membranes with polyethylene glycol( PEG),Li Cl and Ca Cl2 as additives were fabricated by dry-wet spinning technology. The effects of adding amount of PEG in the casting solution during membrane fabrication on the performance of...
A segment of block copolymers with poly(m-phenylene isophthalamide) (PmIA) length was prepared. The block copolymers were prepared using various molecular weights of polytetramethylene glycols (PTMG) as the soft segment, and 4,4-diphenylmethane diisocyanate (MDI), 1,4-butane diol (BD), and ...
Poly (m-phenylene isophthalamide) (PMIA) has great thermal resistivity (Tg270°C), good chemical stability, elongation at break and toughness as well as high mechanical strength, which explains PMIA is an outstanding membrane material [38], [39], [40]. Wang et al. fabricated a PMIA hollo...
Recently, nylon-6 NF/N filters with cavity structures (enlarged voids between the adjacent fibers) were designed and fabricated by embedding PAN nanofibers or poly(m-phenylene isophthalamide) staple fibers into the membranes, and their air permeability was effectively enhanced. However, the nanonets...
