聚丙烯腈纤维是合成纤维的一种,外观蓬松、柔软,有良好的弹性与保暖性。
但由于它是疏水性纤维,吸湿性差、易起静电,其穿着舒适性远远不及羊毛,从而限制了它的进一步发展。
本论文首次提出用蛋白质对聚丙烯腈纤维进行表面接枝改性的机制:聚丙烯腈纤维的蛋白质表面接枝改性由聚丙烯腈纤维的水解、酰氯化及与蛋白质的接枝反应三部分组成。
通过水解将聚丙烯腈纤维表面的氰基极性基团(–CN)转化为成羧基基团(–COOH),从而为酰氯化提供条件。
通过羧基与氯化亚砜之间的酰氯化反应,赋予纤维以酰氯强极性基团(–COCl),这是实现聚丙烯腈纤维与蛋白质接枝的基础。
接枝是通过酰氯基团与蛋白质中的氨基(–NH2 )和羟基(–OH)发生不可逆氮酰化和酯化反应实现的。

X射线图显示出轮廓明显的半圆形晶体反射，这主要是因为与分子链方向平行的不间断晶格面所致。
另外，由于明显地缺乏与分子链方向成横向关系的确定的晶格面，因此只有弥散“非晶态”的光强度贡献才可以观察到。

The chemical structure and morphologies of the modified PAN fibers were studied. The water transportation, water retention, moisture absorption and mechanical properties of the fibers were discussed. Results show that there is no residual PEG in modified PAN fibers after drawing process in hot water bath and post-treatment. With the increase in PEG molecular weight, the fiber surface grooves become deeper, the inner pore size increases, while the mechanical properties decrease. The water absorbing and transferring capabilities of the modified PAN fibers can be improved in varying degrees due to the different pore structures left by series molecular weight of PEGremoving. © 2010 The Korean Fiber Society and Springer Netherlands.(11 refs)Main heading:Spinning (fibers)Controlled terms:Blending - Fibers- Mechanical properties - Molecular weight - Polyacrylonitriles- Polyethylene glycols - Polyethylene oxides - Polyethylenes - Textile blends - Thermoplastics - Water absorption- Water treatmentUncontrolled terms:Chemical structure - Drawing process - Fiber surface - Hot water - Moisture absorption - PAN fiber- Polyacrylonitrile fiber- Porous fibers- Post treatment - Water baths - Water retention - Water transport - Water transportation - Wet-spinningClassification Code:951 Materials Science - 819.5 Textile Products and Processing - 819.3 Fiber Chemistry and Processing - 817 Plastics and Other Polymers: Products and Applications - 815.1.1 Organic Polymers - 812 Ceramics, Refractories and Glass - 802.3 Chemical Operations - 801 Chemistry - 445.1 Water Treatment TechniquesDatabase:Compendex七、Springlink1.

Increasing the weight gain of PANF-g-HPEI from 10% to 90% resulted in the increase of its COOH, amino and amide groups from 0.12 to 1.86 mmol/g, 1.44 to 8.90 mmol/g, and 0.67 to 2.12 mmol/g, respectively. Dye adsorption experiments demonstrated that (1) such PANF-g-HPEIs could effectively adsorb anionic Methyl Orange (MO) or cationic Methylene Blue (MB), through the pretreatment with acidic or basic solution, respectively; (2) PANF-g-HPEIs could selectively adsorb the anionic MO or the cationic MB from MO/MB mixture through the pretreatment with solution of pH = 5 or 10, respectively; (3) the cationic or anionic dyes adsorbed by PANF-g-HPEIs could be reversibly desorbed by the aqueous solution of pH = 1 or 10, respectively; (4) PANF-g-HPEI could be recycled efficiently, and its dye adsorption performances did not show pronounced loss even after 10 adsorption/desorption cycles, superior to PANF treated with the low molar-mass polyamines.Graphical abstractKeywordsPolyacrylonitrile fiber; Hyperbranched polyethylenimine; Recyclable; Selective adsorption; DyeCorresponding author.

Radiation-induced oxidation degradation and crosslinking was evaluated by measuring the gel fraction. It was found that radiation oxidation took place mainly on the fiber surface due to the limited penetration of oxygen into PAN fibers from the surface, and the oxidation thickness increased with the oxygen pressure. Chain scission was dominant in the oxidized area, and crosslinking occurred in the inner part of the fibers. However, the oxidized regions of the fibers can be converted to gel via crosslinking by thermal curing at 160 °C in a N2 atmosphere. Higher extents of radiation oxidation degradation led to a greater increase in the gel fraction. These results suggest that the radiation treatment of PAN fibers prior to thermal oxidation may be useful for manufacturing carbon fibers.KeywordsPolyacrylonitrile fiber; Radiation oxidation; Thermal curingCorresponding author.
