Description

A new material system, consist of glass fiber/poly(glycidyl methacrylate) composites, was synthesized by integrating surface-initiated atom transfer radical polymerization (SI-ATRP) technique with the mussel-inspired polydopamine (PDA) chemistry. The homogenous PDA layer deposited onto the glass fiber mats (GFMs) facilitated the anchoring of ATRP initiators and controlled growth of poly(glycidyl methacrylate) (PGMA) brushes from the GFMs were then performed by the initiators for continuous activator regeneration (ICAR) ATRP method. Post functionality for GF/PGMA composite (GFPGMAC) was realized by nucleophilic substitution of the abundant epoxy groups and 4'-aminobenzo-15-crown-5 (B15C5). Lithium isotopes separation by GFPGMAC-B15C5 exhibited a maximum adsorption capacity of 6.46 mg·g-1 and separation factor was 1.307±0.002 in optimal experimental conditions. (author)
