고선량율 전자가속기를 이용하여 폴리에스터/면혼방직포에 난연제 (Fyrol 76)를 그래프트 중합반응 시키는 방법의 개선을 시도하였다. 폴리에스터/면(65/35) 혼방직포에 고착시킨 난연제는 Fyrol 76을 사용하였다. 팽윤조건과 단위체와 접촉시간 및 선량율 등을 적절히 조절하므로써 섬유체 난연제를 그래프트 반응시킬 수 있었으며, 그래프트 중합반응의 수율은 방사선 선창과 선팽윤(先膨潤) 조건에 좌우되었다. 난연제로 처리한 혼방직포의 난연성 효과는 산소 지수로 측정하였다. 폴리에스터/면혼방직포에 난연제를 그래프트 중합반응... -
Radiation Grafting of Hydrophilic Monomers onto Polyester
Park. Jae-Ho, Lee. Chong-Kwang, Lee. Kwang-Jin 한국원자력학회 Journal of the Korean Nuclear Society 12 Pages

본 실험은 방사선을 이용하여 Polyester 직포의 흡수성과 염색성 그리고 대전성을 증진시키기 위한 연구로서 실온하에서 함침법으로 Acrylic acid또는 4-vinylpyridine을 Polyester 직포에 접목시켰다. Polyester 직포를 25$^{circ}$또는 7$0^{circ}C$에서 Acrylic acid나 Acrylic acid와 4-vinylpyridine의 emulsion 용액에 함침시켰으며 함침된 Polyester 직포를 질소깨스 존재 하에서 Co-60의 l-rays로 조사시켰다. Acrylic acid가 접목된 Polyester 직포를 Sodium carbonate, Calcium acetate 또는 Potassium persulfate로 처리하였을... -

본 연구에서 염화비닐벤질(vinylbenzyl chloride) 단량체는 동시조사방법을 이용하여 poly(tetrafluoroethylene-co-hexafluoropropylene)(FEP), poly(tetrafluoroethylene-co-perfluoropropylvinyl ether)(PFA), poly(ethylene-co-tetrafluoroethylene)(ETFE) 불소고분자 필름에 성공적으로 그래프트되었다. 실험 결과 같은 조사조건을 적용할 경우 다른 불소고분자 필름보다 ETFE 불소필름에 PVBC 고분자가 쉽게 그래프트됨을 확인하였다. 그래프트된 필름들은 FTIR, TGA, SEM-EDS 기기들을 사용하여 분석하였다. 그래프트된 필름의... -

Novel reforming of pyrolized fuel oil by electron beam radiation for pitch production
Jin-Young Jung, Mi-Seon Park, Min Il Kim and Young-Seak Lee 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.4 5 262-267 (6 pages)
Aromaticity (Fa), average molecular weight, solubility, softening point, and density increased in proportion to the absorbed dose of E-beam radiation, with the exception of the highest absorbed dose, due to modification by free radical polymerization and the powerful energy intensity of E-beam treatment. The H/C ratio and yield exhibited the opposite trend for the same reason. These results indicate that novel E-beam radiation reforming is suitable for the preparation of aromatic pitch with a... -
Preparation of pitch from pyrolized fuel oil by electron beam radiation and its melt-electrospinning property

or E-beam radiation treatment) and the use of a catalyst. The softening point and molecular weight were increased in proportion to absorbed doses of E-beam radiation and added AlCl3 due to the formation of pitch by free radical polymerization. The range of the molecular weight distribution of the modified pitch becomes narrow with better spinning owing to the generated aromatic compounds with similar molecular weight. The diameter of melt-electrospun pitch fibers under applied power of 20 kV...
