2019年11月1日 · PGMA was functionalized with aminophosphonic groups to sorb rare earth elements. XPS, FTIR and molecular modeling were applied for characterizing metal binding. Sorption isotherms and uptake kinetics are modeled for La (III) and Y (III) recovery. Metal desorption and sorbent recycling are highly efficients.

通过种子聚合制备了单分散的聚甲基丙烯酸缩水甘油酯/聚苯乙烯（PGMA / PS）各向异性微球。 从SEM图像中，已知获得的PGMA / PS微球具有三种不同的形态：树莓形，高尔夫球形和多孔结构。 基于这些微球的成功制备，通过碱性溶液中的多巴胺自动聚合制备了牛血清白蛋白（BSA）印迹的PGMA / PS微球。 由于多巴胺不会影响蛋白质结构的有效性，因此MIP表面上的印迹腔结构可以完全匹配模板蛋白质分子。 所获得的微米级BSA印迹PGMA / PS微球具有出色的饱和吸附容 …

2020年3月7日 · PGMA microspheres were prepared and modified by N-Methyl-D-glucamine, followed by free radical polymerization of acrylamide in the presence of microspheres to construct nanocomposite hydrogel. FT-IR, XPS and DLS verified a successful introduction of hydroxyl groups during modification.

2023年12月31日 · Sun et al. melt compounded PGMA functionalized CNCs up to 2 wt% in PLA/PBAT blends in order to enhance the strength and toughness of the final blend nanocomposites. They showed that the CNC-g-PGMA incorporation significantly reduced the PBAT droplet size with enhanced interfacial compatibility between PLA and PBAT [35].

2009年8月15日 · Attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) confirmed the grafting of P (PEGMA) and PGMA chains. Water contact angle measurements indicated that the introduction of P (PEGMA) and PGMA graft chains promoted remarkably the surface hydrophilicity of PSF membranes.

在最后一步中，通过在甲醛存在下使膦酸基团反应到胺官能团上，将亚甲基膦酸基团接枝到DETA-PGMA上，以生产聚氨基膦酸吸附剂（PPA-PGMA）。 通过元素分析，FTIR光谱，XPS，XRD，TG-TDA和SEM-EDX分析对吸附剂进行表征。 测试了材料对La（III）和Y（III）的吸附性能：在研究吸收动力学，吸附等温线（和热力学），金属解吸和吸附剂再循环之前，研究了pH对吸附性能的影响。 最大吸附容量达到0.79 mmol La g -1 和0.73 mmol Y g 在pH 5（最佳 …

2018年2月8日 · In this article, a new adsorbent (A-PGMA) has been synthesized via functionalizing poly (glycidyl methacrylate) microsphere with 2-aminothiazole and used to adsorb gold ions from aqueous solutions.

2022年4月15日 · Then, a feasible and efficient approach to quantitatively measure the molecular weight of surface-grafted PGMA onto insoluble MWCNTs was proposed by properly analyzing X -ray photoelectron spectroscope (XPS) and thermos-gravimetric analyzer (TGA) data.

XPS measurements were carried out to evidence the success of the grafting reactions. Figure 4 depicts the C 1s spectra of the unmodified PGMA microparticles as well as the modified particles...

2019年2月7日 · Poly (glycidyl methacrylate) (PGMA) is prone to modifications with different functional groups, magnetic fluids or direct coupling with biological molecules. The...
