“…Currently, transition metals are found a better flame retardant additive toward the above problems, which can not only effectively promote the char formation during the combustion but also perform well in blocking the heat exchange and reducing the toxic smoke release . Considering the advantages and disadvantages of different flame retardants, many transition metal compounds, such as Ni(OH) 2 , Co 2 P, Cu\Ni complexes, and MoS 2 , are used to improve the flame retardance of polyphosphazene flame retardants.…”

A novel PZS@CS hybrid structure was synthesized for enhancing the flame retardancy of polyethylene terephthalate (PET). The PZS@CS hybrids showed significant flame retardance. For example, the incorporation of 6 wt% PZS@CS obviously brought about an 8.8% increase of limiting oxygen index value (29.3%) and passed the vertical burning test UL-94 V-0 level, accompanied with the sharp reduction of heat and smoke release. The flame retardant mechanism of PZS@CS hybrids was fully studied by the Thermogravimetric Analysis (TGA), pyrolysis-gas chromatography-mass spectrometry, and Raman methods, and the results showed that the improvement of flame retardancy was mainly ascribed to the synergistic effect of PZS and CS phases in both the condensed and the gas phase. Rheological results showed that PZS@CS hybrids improved the melt complex viscosity of PET composites and the well compatibility of PET matrix and PZS@CS hybrids was also proved by the improvement of mechanical properties.

T WO triazole Schiff base derivatives N-(furan-2-ylmethylene)-1H-1,2,4-triazole-3-amine (FTA), N-(thiophene-2-ylmethylene)-1H-1,2,4-triazole-3-amine (TTA) and their metal complexes Co(II), Ni(II), Cu(II) and Zn(II) were synthesized under microwave irradiation. The structure of these compounds has been investigated by using elemental analysis, FT-IR, UV-Vis spectrometric methods, magnetic susceptibility, mass spectra, NMR, ESR and thermal studies. The antimicrobial activities of the prepared ligands and their respective Zn (II) complexes were studied against the bacterial (positive and negative) grams and fungal strains. The inhibitive characteristics of Schiff base ligands on C-steel corrosion in hydrochloric acid were studied using weight loss measurements. The prepared Schiff base derivatives show high inhibition efficiency and their adsorption surface was found to obey Langmuir model. The data also revealed that FTA is less than TTA in terms of inhibiting efficiency.

Polyurethanes as one of the leading elastomers are explored in academics as well as in industry. These are segmented macromolecules having alternate sequence of soft and hard segments. Structure-property correlation between these segments has been extensively reported in the literature. PUs are used widely in coatings, varnishes, glues, foams, adhesives, sealants, automobile parts, synthetic leather etc. Its application in biomedical devices is also growing rapidly. It is therefore need to highlights the recent developments in this fast growing field. The present article is summarized the conventional and ecofriendly synthetic routes for the preparation of PUs. Conventionally, PUs was synthesized by isocyanates route, later shortcoming of this method explore new synthesis method in which either used biobased polyol or non isocyanates route for preparation of ecofriendly PUs. The applications of different types of PUs coating in various fields are also highlighted in this review.
