Preparation and Characterization of Polypyrrole/Attapulgite with Organic Surface Modification Conducting Composite

Abstract:

Attapulgite was organic surface modified with silane coupling agent (KH570) and acetone, with ferric chloride (FeCl3∙6H2O) as the oxidant, sulfamic acid(SA) as dopant, prepared polypyrrole/attapulgite with organic surface modification conducting nano-composite materials (PPy/ATTP-KH) by chemical oxidation polymerization, and using IR, XRD and SEM characterization methods to characterize Internal structure of composite materials obtained. The results show that in the condition of n(Py):n(FeCl3∙6H2O):n(SA) =1:1:0.5, and with the increase of contents, composite conductivity increased and then decreased, when the contents of attapulgite is to 50%, the conductivity reaches maximum 30.0 S•cm-1. We can see from the IR spectrum, silane coupling agent and hydroxyl of attapulgite surfaces have a chemical bonding, and plays a good modification to the surfaces of attapulgite, Thereby enhancing the conductivity of the composite materials.
