詳細(xì)介紹
設(shè)計(jì)用于高速GPC分析，HSPgel色譜柱提供準(zhǔn)確與精確的分子量測(cè)定，提高樣品通量，并顯著降低了溶劑損耗與處理成本。
Waters提供6.0x150mm規(guī)格的HSPgel色譜柱，共三個(gè)系列：
HSPgel HR系列
專門設(shè)計(jì)用于高分辨、室溫下分析有機(jī)聚合物。這些色譜柱保存于THF，允許一次溶劑轉(zhuǎn)換，轉(zhuǎn)換成甲苯、二氯甲烷或氯仿。
HSPgel RT系列
設(shè)計(jì)用于常規(guī)的、室溫下分析有機(jī)聚合物。這些色譜柱保存于THF，允許多次溶劑轉(zhuǎn)換，從THF轉(zhuǎn)換成甲苯、氯仿、二氯甲烷、DMF、DMSO等。
HSPgel HT系列
專門設(shè)計(jì)用于從室溫到高溫(180 °C)條件下的聚合物分析。色譜柱保存在THF或ODCB中。保存于ODCB的色譜柱可以直接轉(zhuǎn)換到TCB溶劑體系。這些色譜柱能夠忍受多次溶劑轉(zhuǎn)換。
Improved properties of chemically modified graphene/poly(methyl methacrylate) nanocomposites via a facile in-situ bulk polymerization
The nanosheet of graphene was chemically modified by long alkyl chain for enhanced compatibility with polymer matrix and graphene/poly(methyl methacrylate) (PMMA) nanocomposites with homogeneous dispersion of the nanosheets and enhanced nanofiller-matrix interfacial interaction were fabricated via a facile in-situ bulk polymerization. The nanocomposites were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, Scanning electron microscopy and thermogravimetry. The results showed that the graphene nanosheets were fully exfoliated in PMMA matrix and the thermal and mechanical properties of the nanocomposites were significantly improved at low graphene loadings. Large shifts of 15°C in the glass transition temperature and 27°C improvement of onset thermal degradation temperature were achieved with graphene loading as low as 0.07 wt%. A 67% increase in tensile strength was also observed by the addition of only 0.5 wt% graphene. The method used in this study provided a novel route to other graphene-based polymers.
