文摘
Ferrocene-based derivatives are widely used as ferrocene-based burning rate catalysts (BRCs) for ammonium perchlorate (AP)-based propellant. However, in long storage, small ferrocene-based derivatives migrate to the surface of the propellant, which results in changes in the designed burning parameters and finally causes unstable combustion. To retard the migration of ferrocene-based BRCs in the propellant and to increase the combustion of the solid propellant, zero to third generation ethylene diamine-based ferrocene terminated dendrimers (<strong class="boldFont">0Gstrong>, <strong class="boldFont">1Gstrong>, <strong class="boldFont">2Gstrong> and <strong class="boldFont">3Gstrong>) were synthesized. The synthesis of these dendrimers was confirmed by <sup>1sup>H NMR and FT-IR spectroscopy. The electrochemical behavior of <strong class="boldFont">0Gstrong>, <strong class="boldFont">1Gstrong>, <strong class="boldFont">2Gstrong> and <strong class="boldFont">3Gstrong> was investigated by cyclic voltammetry (CV) and the burning rate catalytic activity of <strong class="boldFont">0Gstrong>, <strong class="boldFont">1Gstrong>, <strong class="boldFont">2Gstrong> and <strong class="boldFont">3Gstrong> on thermal disintegration of AP was examined by thermogravimetry (TG) and differential thermogravimetry (DTG) techniques. Anti-migration studies show that <strong class="boldFont">1Gstrong>, <strong class="boldFont">2Gstrong> and <strong class="boldFont">3Gstrong> exhibit improved anti-migration behavior in the AP-based propellant.
