در این پروژه، تغییر ساختار ptfe در اثر تخریب با پرتو الکترون گزارش شده و در حین کار از تکنیک های مختلف ftir, xrd,dsc,esr و اندازه گیری خواص فیزیکی مکانیکی استفاده شده است.
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
crosslinked poly(acrylic acid)s were prepared using two types of crosslinker by precipitation polymerization method in a binary organic solvent. n,n’-methylenebisacrylamide (mba) and polyethylene glycol dimethacrylate (pegdma-330) were used as low-molecular weight and long-chain crosslinkers, respectively. the effect of various types of crosslinkers on polymer characteristics (i.e., gel content...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
tricalcium phosphate as hydroxyapatite is used as a suspension stabilizer in styrene polymerization process. particle size of tcp plays an essential role in the particles’ size distribution and geometrical form of polystyrene products. as the particle size of tcp is reduced, there will be much better chance to engulf the styrene particles. the higher the number of tcp particles surrounding each...
abstract in order to analyse of soil volume humidity and water potential of turf using of different amounts of water absorbent polymer in sort of acryl amid potassium, an experiment conducted at research farm of meybod azad university in 2005. the experiment was conducted in randomized completed block design in four levels of polymers of 3, 6, 12 and 24 gr/m2 and 0 gr/m2 of polymers was conside...
