采用~(60)Coγ射线对苯乙烯二乙烯基苯共聚物(SDB)和在SDB上担载金属铂后的疏水催化剂(Pt—SDB)在限量空气和氘气气氛下进行辐照,辐照剂量范围为200～1000 kGy。辐照后,通过扫描电镜(SEM)、傅立叶变换红外光谱(FT-IR)、差热扫描量热法(DSC)和热重(TG)等分析方法研究了辐照对SDB和Pt—SDB表观型貌、热性能、化学结构和氢同位素交换的影响。研究结果表明:在200～1 000 kGy的剂量范围内,辐照对SDB的表观型貌没有破坏性影响;辐照没有引起SDB的热性能和结构变化;氘气气氛下SDB和Pt—SDB有一定的氢同位素交换,但辐射对氢同位素交换影响不大。
Irradiation was carried out under a limited air and deuterium atmosphere using ~ (60) Coγ-ray-pair styrene-divinylbenzene copolymer (SDB) and a hydrophobic catalyst (Pt-SDB) The dosage range is 200 to 1000 kGy. After irradiation, the effects of irradiation on the SDB and Pt-SDB spectra were studied by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC) and thermogravimetry Appearance, Thermal Properties, Chemical Structure and Hydrogen Isotope Exchange. The results show that the radiation has no detrimental effect on the apparent appearance of SDB in the dose range of 200-1 000 kGy; the thermal properties and structure change of SDB are not induced by irradiation; the densities of SDB and Pt-SDB There is a certain hydrogen isotope exchange, but radiation has little effect on hydrogen isotope exchange.
