“…Compared with the traditional solution grafting and vapor phase grafting, melt grafting has two advantages. One is that the melt grafting requires much less time, around tens of minutes, than hours in solution or vapor phase grafting . The other is that melting grafting achieves the modification of polymer bulk, more efficient than the only surface modification in solution grafting and vapor phase grafting .…”

The surface modification of isotactic polypropylene by dielectric barrier discharge of air plasma is studied. The air plasma induces melt grafting of pentaerythritol triacrylate onto polypropylene, which successfully introduces polar long-chain branching (LCB) structure into polymer bulk. The results of X-ray photoelectron spectroscopy show that C─O and C O oxygen-containing functional groups are formed on polypropylene surface, of which the functional groups contents can reach 24.4 and 12.0%, respectively. It is found that there is an optimum plasma treatment time of 4 min to obtain the high peroxides concentration of about 3.38-3.69 × 10 −7 mol cm −2 . The highest grafting degree of this plasma method is 1.79%, which achieves the same level as the chemical grafting method. The molecular structural change of the graft-modified polypropylene, in the form of LCB is investigated by shear rheology.

“…However, due to its poor moisture absorption and air permeability, the property of wearing comfort is not excellent. To solve this problem, there are many modified methods executed such as blending modification [1][2][3], copolymerization modification [4][5][6], surface modification [7][8][9], special-section modification [10,11] and postfinishing [12][13][14]. For example, Pappas et al [15] functionalized the PA surface by the addition of new reactive chemical groups to improve its wettability.…”

To improve the moisture absorption and air permeability of polyamide (PA) fibers, the modified fibers with porous structure were fabricated by melt spinning using polyethylene glycol (PEG) as the pore-forming agent due to its high solubility in water. The effects of pores caused by different PEG contents on the structure and properties of modified fibers were analyzed by electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and water contact angle. These results indicate that the porosity of modified fibers increases with PEG content increasing. Moreover, the formation of pores obviously affects the crystal forms of modified fibers. The alpha crystal gradually decreases and the gamma crystal increases with the porosity increasing. Furthermore, with respect to the modified fibers obtained from 47.33% PEG content, its water absorption increases from 3.78% of pure PA to 19.76% and its contact angle decreases from 116° to 85°. In addition, due to the interaction of hydrogen bond occurring between PA and PEG during the spinning process, the elongation at break, rupture work, and initial modulus of modified fibers were improved when the porosity was not more than 4.23%.

“…The principle of plasma grafting consists of using ionized high-energy particles to bombard the surface of the material to produce active sites (e.g., free radicals), triggering the grafting reaction of monomers on the surface. Grafting modification of PP fibers can greatly improve the hydrophilicity, functionality, and other physical and chemical properties [12]. Basarir et al found that the electrochemical properties of PP films were improved as a result of activation with plasma followed by polymerization of the acrylic monomers on the surface [13].…”

To improve the adsorption selectivity towards hexavalent chromium anion (Cr(VI)), surface Cr(VI)-imprinted polypropylene (PP) fibers were fabricated by the plasma-mediated grafting strategy. Hence, a non-thermal Rradio frequency discharge plasma irradiation followed by a gaseous phase grafting was used to load acrylic acid (AA) onto PP fibers, which was afterwards amidated with triethylenetetramine and subjected to imprinting with a Cr(VI) template. The plasma irradiation conditions, i.e., gas species, output power, pressure, and time, were optimized and then the influence of grafting time, pressure, and temperature on the grafting degree of AA was investigated. Scanning electron microscopy and Fourier transform infrared spectroscopy were used for the characterization of pristine and modified fibers and to confirm the synthesis success. The hydrophilicity of modified fibers was greatly improved compared with pristine PP fibers. The adsorption thermodynamics and kinetics of Cr(VI) were investigated, as well as the elution efficiency and reusability. The prepared imprinted fibers showed superior adsorption selectivity to Cr(VI) compared with non-imprinted fibers. Finally, the stability of the imprinted fibers against the oxidation ability of Cr(VI) is discussed.
