作者:Gao, JL (Gao, Jinglong)[ 1 ] ; Ni, ZC (Ni, Zaochun)[ 1 ] ; Liu, YH (Liu, Yanhui)[ 1 ] E-POLYMERS 卷: 16 期: 2 页: 111-115 DOI: 10.1515/epoly-2015-0223 出版年: MAR 2016 查看期刊信息 摘要 The effect of electron beam (EB) irradiation on polytetrafluoroethylene (PTFE) film was studied in air at room temperature. The structural changes of the PTFE film irradiated by EB were determined by Fourier transform infrared (FTIR) and X-ray diffraction (XRD). The morphological changes on the film surface were described using scanning electron microscopy (SEM). The surface hydrophilicity of the modified film was characterized through water contact angle measurement. The results show that scission of the chain on the surface of PTFE film was induced by EB irradiation. The atomic ratio of F/C decreased and the atomic ratio of O/C increased. The surface roughness of the irradiated sample increased. In the case of irradiation in the presence of residual air, carboxylic acid fluoride groups appear and can hydrolyze to carboxylic groups in the surface-near regions. These polar groups significantly reduced the hydrophobicity and oleo-phobicity of the PTFE film and consequently cause the decline of the water contact angle of the film surface. XRD analysis reveals an increase of the crystallite size of PTFE along with the increasing time of the irradiate. 关键词 作者关键词:crystallite size; electron beam irradiation; modification; polytetrafluoroethylene; wetting property KeyWords Plus:TRIBOLOGICAL PROPERTIES; POROUS MEMBRANES; BINARY MONOMERS; WEAR BEHAVIOR; EPDM RUBBER; FRICTION 作者信息 通讯作者地址: Liu, YH (通讯作者) 显示增强组织信息的名称 Shenyang Ligong Univ, Sch Mat Sci & Engn, Shenyang 110168, Liaoning, Peoples R China. 地址: 显示增强组织信息的名称 [ 1 ] Shenyang Ligong Univ, Sch Mat Sci & Engn, Shenyang 110168, Liaoning, Peoples R China 电子邮件地址:liouyh@126.com 基金资助致谢 基金资助机构 授权号 Chinese National Science Foundation 51472048 Shenyang Municipal Science and Technology Foundation F15-199-1-18 F15-173-6-00 Liaoning Municipal Science and Technology Foundation 2015004001 查看基金资助信息 出版商 WALTER DE GRUYTER GMBH, GENTHINER STRASSE 13, D-10785 BERLIN, GERMANY 类别 / 分类 研究方向  olymer ScienceWeb of Science 类别 olymer Science文献信息 文献类型:Article 语种:English 入藏号: WOS:000374996700003 ISSN: 1618-7229 期刊信息 Impact Factor (影响因子): Journal Citation Reports® 其他信息 IDS 号: DK5YI Web of Science 核心合集中的 "引用的参考文献": 15 Web of Science 核心合集中的 "被引频次": 0 引文网络 0 被引频次 15 引用的参考文献 查看 Related Records 查看引证关系图查看引证关系图 当有人引用此记录时接收电子邮件创建引文跟踪 (数据来自 Web of ScienceTM 核心合集) 全部被引频次计数 0 / 所有数据库 0 / Web of Science 核心合集 0 / BIOSIS Citation Index 0 / 中国科学引文数据库 0 / Data Citation Index 0 / Russian Science Citation Index 0 / SciELO Citation Index 使用次数 最近 180 天: 0 |
