copolymer by graft copolymerization technique

Polyacrylonitrile (PAN) fiber is used in the textile industry frequently and has
a prominent place among the synthetic fibers. It has good thermal stability,
compatibility with polar materials due to containing the high polar nitrile groups,
hardness and high abrasion resistance. However, in spite of many superior properties
of PAN fibers, some of their poor features such as low moisture absorption and poor
antistatic properties limit their further usage. So, surface modification is particularly
important for fiber/fabric materials and in order to modify of surface of PAN fiber,
functional monomers can be incorporated into fiber structure. One of the mostly
used methods for this purpose, graft copolymerization method was used to graft
Hydroxyethyl Methacrylate (HEMA) onto PAN fiber directly to get the surface modified fibers. The grafting processes were
carried out in aqueous medium containing benzoyl peroxide solution in acetone as initiator and HEMA solution at suitable
concentrations. PAN fibers grafted HEMA at different percentages was prepared depend on the polymerization conditions
such as initiator and monomer concentration, polymerization temperature. Grafting yield was determined gravimetrically
and the maximum grafting yield was obtained as about 90% under the conditions investigated. The chemical structure of
PAN fiber-g-poly(hydroxyethyl methacrylate) was characterized by FTIR and H-NMR spectroscopic techniques. The surface
morphology of the grafted fiber was studied by SEM.
