Abstract It was found that montmorillonite intercalated with ϵ‐caprolactam. X‐ray diffraction revealed the chain axes of ϵ‐caprolactam were parallel to plates. The swollen by molten at 200°C. ϵ‐Caprolactam and 6‐aminocaproic acid (accelerator) polymerized 260°C for 6 h, yielding a nylon 6‐clay hybrid. transmission electron micrography silicate layers hybrid uniformly dispersed in matrix. Mechanical properties improved. strength modulus increased compared previously reported clay‐hybrid (NCH)...
Magnesium hydride owns the largest share of publications on solid materials for hydrogen storage. The group international experts contributing to IEA Task 32 Hydrogen Based Energy Storage recently published two review papers presenting activities focused magnesium based and Mg compounds energy This article not only overviews latest both fundamental aspects Mg-based hydrides their applications, but also presents a historic overview topic outlines projected future developments. Particular...
Abstract Nylon 6–clay hybrid is a molecular composite of nylon 6 and uniformly dispersed silicate layers montmorillonite. One‐pot synthesis the was carried out by following procedures. Montmorillonite in water, then ε‐caprolactam, acid (phosphoric acid, hydrochloric benzenesulfonic isophthalic trichloroacetic or acetic acid), 6‐aminocaproic were added to dispersion. The mixtures reacted at 260°C for h, yielding hybrids (1potNCHs). X‐ray diffraction revealed that 1potNCH phosphoric matrix....
Abstract Various nylon 6‐clay hybrids, such as molecular composites of 6 and silicate layers montmorillonite saponite, NCHs NCHPs, respectively, have been synthesized. Sorption water in those hybrids was measured to estimate the resistance permeation. The diffusion coefficient D partition K were obtained from sorption curves. permeation NCH superior that because a decrease . In NCHP, saponite had smaller effect on increase resistance. coefficients NCHP decreased with an amount clay minerals....
Liquid hydrogen carriers are considered to be attractive storage options because of their ease integration into existing chemical transportation infrastructures when compared with liquid or compressed hydrogen. The development such forms part the work International Energy Agency Task 32: Hydrogen-Based Storage. Here, we report state-of-the-art for ammonia-based and organic carriers, a particular focus on challenge ensuring easily regenerable, high-density storage.
Abstract We synthesized nylon 6‐clay hybrid materials using four types of clay minerals, montmorillonite, saponite, hectrite, and synthetic mica. The mechanical properties their injection molded specimens were measured according to ASTM. Nylon montmorillonite was superior the other hybrids in properties. This might result from difference interaction between molecules silicates hybrids. To clarify this hypothesis, we intercalated compounds minerals with glycine as model hybrids, analyzed 15 N...
Abstract Nylon‐6–clay hybrid (NCH) is a molecular composite of Nylon‐6 and uniformly dispersed silicate monolayers montmorillonite. In this study, orientation montmorillonite crystallites in the NCH film was measured by x‐ray diffraction transmission electron micrography (TEM), which revealed that, layers (γ‐form) have planar orientation, independent content. Based on crystal structure model proposed Bradbury et al., it seems that hydrogen bonded sheet plane {020} or zigzag backbone {110}...
Ammonia is well-known as a hydrogen carrier owing to its high capacity (17.8 wt %). However, the toxicity and storage pressure limit application of ammonia. Consequently, storing ammonia in solid state has become promising method utilize for practical applications. In this review, absorption properties metal hydrides, halides, borohydrides form amides ammine complexes with various coordination numbers have been systematically summarized. Through research, we found correlation between...
Abstract Nylon 6‐clay hybrid (NCH) is a molecular composite of 6 and uniformly dispersed silicate monolayers montmorillonite. In this study the preferred orientation montmorillonite Nylon‐6 crystallites in thick (3 mm) injection‐molded bar NCH has been investigated using x‐ray diffraction electron micrography (TEM). It clear that triple layer structure consisting surface, intermediate, middle layers which have different orientation. surface both chain axes are parallel to though latter...
