“…Thus, Brown and Butler (1997) and Berry (1987Berry ( , 1988 have recorded LV-SEM images of RuO 4 -stained bulk specimens of polymer blends after removal of an overstained surface layer. To image unstained polyolefins (isotactic polypropylene and high-density polyethylene [iPP]) containing antistatic additives, Dudler et al (2000) glued thick films (50-2200 µm) to an aluminium stub using a conductive carbon adhesive.…”

Morphologic characterization of polymers by scanning electron microscopy (SEM) is often made difficult by their sensitivity to electron beam damage. We describe here a specimen preparation method for the imaging of polymer blends by low-voltage SEM (LV-SEM) that improves their stability in the electron beam and hence facilitates focusing and recording of high magnification images. Its application to nanosized core-shell latexes embedded in a polymethylmethacrylate matrix and semi-crystalline polypropylene/ethylene-propylene rubber blends is discussed.

“…The use of polystyrene latex in filled polymer composites has been investigated extensively [31][32][33][34][35][36][37][38][39][40][41][42][43]. The common conductive fillers include ionic conductive polymers [44], conductive carbon black particles [45], and conductive nanotubes [37,[46][47][48][49][50]. Carbon is the most commonly used filler for polymer matrix composites, resulting in composites with increased strength, thermal, and electronic properties [45,51].…”

The interest in exploring porphyrin-based nanostructures for artificial solar radiation harvesting stems from their structural similarity to chlorophylls. In nature, the precise organization and orientation of the chlorophylls result in efficient absorption of light energy. Inspired by these naturally occurring architectures relevant optical studies including the dynamics of intermolecular and intra-molecular processes of the porphyrin nanorods were investigated. The design of artificial light harvesting systems requires several key factors, such as absorption in the UV-visible and nearinfrared wavelengths, energy transfer ability and the selection of light absorbing pigments. Another key factor is the organizational structure through which the components will interact. We attempted to accomplish this by incorporating porphyrin nanorods into polymer matrices and this will also aid in achieving an arrangement where they can be directly used as devices. The nanorods were embedded in a polymeric matrix, using latex technology and electrospinning which gave the possibility of investigating the orientation of nanorods in the polymer. Spectroscopic and microscopic studies were conducted to investigate the optical and morphological properties of the porphyrin nanorods-polymer composites for applications in artificial solar radiation harvesting systems.

“…Most of the studies on antistatic additives that have been carried out deal with the polyolefin to be used in the packaging application. [3][4][5][6] Even though, these additives have been widely used in noncrosslinked polyethylene foam for industrial applications, their performance is not yet fully understood and not even systematically studied, essentially due to the peculiarity of its expanded nature. Thus, up to our knowledge, there is a lack of scientific publications on the subject.…”

Polyethylene foams with different antistatic additives (Atmer 7325, Atmer 7105, and Atmer 190) were prepared by extrusion and stored during 6 months of time span in a real life environment. The antistatic performance was evaluated by measuring the surface resistivity and throughout decay-time experiments. Mechanical properties and migration tests were also performed. It was found that the migration of antistatic agents is in general low enough, which allows to maintain the antistatic performance for periods of time larger than 6 months. The tests revealed that the desired low surface resistance and required low static decay time could be achieved with all the antistatic agents under test. Moreover, the additives with amina (Atmer 7105 and 7325) as an active agent showed slightly better antistatic performance than the one with the ionic agent (Atmer 190). The addition of an antistatic agent does not significantly affect the mechanical behavior of the foam indicating a desired feature concerning industrial applications.
