高分辨色譜柱、高溫色譜柱、高分子量色譜柱

詳細(xì)介紹

Styragel HR(High-Resolution，高分辨)色譜柱

專(zhuān)為低分子量樣品分析所需而設(shè)計(jì)，Styragel HR色譜柱適用于分析低聚物、環(huán)氧樹(shù)脂、以及聚合物添加劑，對(duì)于這些分析物而言高分辨率至關(guān)重要。Styragel HR色譜柱的填料粒徑為5 µm，為低-中分子量樣品提供高分辨率與高柱效。

Styragel HT(High-Temperature，高溫)色譜柱

您可以在Styragel HT色譜柱上使用高溫和強(qiáng)有機(jī)溶劑，而不會(huì)犧牲柱效或柱壽命。色譜柱用堅(jiān)硬的10um顆粒裝填，通常一根色譜柱的典型柱效可達(dá)10,000塔板數(shù)以上。這些色譜柱極為穩(wěn)定耐用，原因是填料粒徑分布范圍很窄，從而確保色譜柱床的穩(wěn)定。Styragel HT色譜柱無(wú)論是室溫還是高溫都適合使用，為中-高分子量范圍的聚合物提供的分辨率。

Styragel HMW(High-Molecule-Weight，高分子量)色譜柱

Styragel HMW色譜柱設(shè)計(jì)專(zhuān)用于分析超高分子量聚合物，這類(lèi)樣品對(duì)于剪切力很敏感。StyragelHMW色譜柱使用10 µm大孔篩板和20 µm填料，讓剪切效應(yīng)最小化?？稍谑覝鼗蚋邷叵率褂?，有很好的柱壽命。


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.
