Field emission gun-scanning electron microscopy

Transmission electron microscopy (TEM) has traditionally been the mainstay of morphological investigations of polyolefins [8], but recent developments in low voltage high-resolution field emission gun scanning electron microscopy (FEG-SEM) [9] and the advent of atomic force microscopy (AFM) and related near-field techniques [10] have challenged its dominance at the length scales of the order of 10 nm, characteristic of both microdeformation (cavitation, fibrils) and structural components of semicrystalline...

The degree of clay dispersion in a PS matrix was characterized by x-ray diffraction analysis (XRD), and electron microscopy that is, scanning [with field emission gun scanning electron microscopy (FEGSEM)] and transmission (TEM) the results are listed in Table 14.1. The XRD scans were obtained at a scan rate 0.3°/min. The specimens were prepared by compression molding at T= 200°C and a compressive...

To characterise surface modifications to the samples, two microscopie methods were used Field Emission Gun Scanning Electron Microscopy (FEG-SEM) and AFM. The structure of the irradiated zone was analysed by Low Incidence X-Ray Diffraction (LI-XRD) technique. 

Employing the field emission gun scanning electron microscopy (FEG-SEM) and TEM to study the morphology of the epoxy reinforced with polystyrene-p-polybutadiene-p-poly(methyl methacrylate) block copolymer (SBM), the nanostructured epoxy matrix with disperse micro-scale phase was revealed. Enhanced flexural properties, which were dependent on the composition of blend was obtained. 

Campos et al. [21] studied sisal flber-reinforced TPS and polycaprolactone, both biodegradable pol5miers. Sisal fibers (5% and 10%) were extruded in a twin-screw extruder with TPS/ polycaprolactone (80 20 wt). Films were produced with a single extruder and analyzed by field emission gun scanning electron microscopy, mechanical tests, thermogravimetric analysis, and differential scanning calorimetry. The morphology of the composites with 10% sisal fiber content presented an interface...
