Preparation and biological thermal properties of sp- bound composites

Abstract

Sporopollenins (Sp) are modified, using a two-step process with amine and benzoyl- isothiocyanate groups. This article describes, the synthesis and characterization of Sp modifi- ed with a series of new benzoylthiourea compounds. The Sp-bound benzoylthiourea derivati- ves of ethylenediamine; Sp-N,N?-(ethane- 1-methylbenzamide-2-benzoylthiourea) 1, diethylen triamine; Sp-N,N?-(N?,N?-diethylamine-1,3-dibenzoylthiourea) 2, N?,N?-bis(3aminopropyl)-a- mine; Sp-N,N?-(N?,N?-d propylamine-1,3-dibenzoylthiourea) 3, N?,N?- bis(3aminopropyl)-eth ylenediamine; Sp-N,N?-(N?,N?-dipropyl-ethanediamide-dibenzoylthiouurea) 4 are synthesi- zed. The compounds are characterized by elemental analysis, FT-IR, UV-VIS, TGA, SEM, GPC and conductance measurement. Sp bound compounds are discussed in terms of biologi- cal, electrical and thermal properties. The antimicrobial activities of Sp bound compounds are also evaluated against seven species of bacteria and mold. The present work shows that ben- zoylthiourea could be utlized to increase the conductivity of insulating Sp. © IDOSI Publications, 2013.
