The versatility of polymer materials is almost legendary, and the rise of high-performance plastics has permanently changed many industrial sectors. Research into new plastics is a topic that has kept Bruker busy for decades. We offer a broad and powerful technology portfolio for all research tasks to keep pace with the next generation of polymers.
无机盐(例如聚磷酸铵或二氧化钛)经常用作聚合物填充材料,以改善加工性,光学特性或阻燃性。必威手机客户端
To completely characterize such composite polymers and identify the inorganic fillers using FT-IR technique only the mid infrared (MIR 400-4000 cm-1)光谱范围不够。MIR范围提供信息以识别聚合物宿主材料,而额外的远红外(FIR低于400厘米必威手机客户端-1) region reveals important information about lattice vibrations of inorganic ionic compounds in the fillers.
布鲁克’s unique FM technology for FT-IR R&D spectrometers merges MIR and FIR spectral range and enables the measurement from 6000 – 50 cm-1在一个没有交换任何光学扫描component (which has been mandatory for spectral range extension into FIR). Find out here, how Bruker FM simplifies polymer characterization.
阻燃剂是用于聚合物的关键成分建筑和工程。没有它们,安全问题将是巨大的,因为某些聚合物表现出明显的燃烧性。在某些材料中,阻必威手机客户端燃剂可以占30%聚合物配方!
An incorrect此类添加性的分布可能导致关键构成effects of the base material.图显示化学物质拉曼图像无卤素火焰的分布在聚酰胺-6基质中的阻燃三聚氰酸(MC)。
显然,阻燃剂没有迁移到整个材料中,并且形成了簇和空隙区域。尽管晶粒尺寸是均匀的,但总体结果并不令人满意,必须优化过程。
Semi-crystalline polymers play a key role in materials science, technology and nature. Approximately two thirds of all synthetic polymers possess the ability to crystallize, which is what makes the diverse use of these materials as molded parts, films or fibers possible in the first place.
使用TD-NMR,可以获得有关最重要的合成半结晶聚合物的大量结晶和结晶动力学的信息。通过确定温度依赖性的松弛行为,可以明确测定聚合物结晶度。另外,可以监测等温结晶。
TD-NMR allows the characterization of the bulk crystallinity and crystallization kinetics of polymers, which predestines the technique for use in research, quality control and processing laboratories.
Thermal analyzers collects the information of the temperature-dependent mass-change (Thermogravimetry), the Enthalpie values (Differential Scanning Calorimetry) or the combination of both. FT-IR on the other hand collects the spectral (molecular) information.
FT-IR combined with Thermal analysis can help to elucidate the fundamental thermal behaviour of new polymer materials. Use it to analyze:
催化剂在聚合物研究和合成中起着基本作用,并且理解化学反应过程对于提高产量,所需聚合物功能的效率至关重要。
FT-IR可用于表征催化剂,其行为和涉及的化学反应。时间分辨的测量值最多为每秒110个光谱,使您可以分析催化过程到低微秒域中。
通过步骤扫描,快速扫描和交织的TRS,可以使用强大的Bruker工具来阐明任何类型的动态过程,例如化学或物理反应。
