| Inhoud: |
Silane coupling agents, namely 3-[(2-aminoethyl)amino]propyltrimethoxysilane (AETMS), 3-[(2-maleicmonoamido)maleicmonoamido]propyltrimethoxysilane (MMTMS) and 3-[(2-maleicdiamido)maleicdiamido]propyltrimethoxysilane (MDTMS), were synthesized and characterized using FT-IR and viscosity studies. The silane coupling agents developed in the present investigation were utilized for coupling hydroxyl terminated polydimethylsiloxane with epoxy matrix and cured with hexamethylenediamine and diaminodiphenylmethane. The siliconized epoxy system developed using MDTMS and cured with diaminodiphenylmethane yielded higher glass transition temperature, better thermal stability and imparts higher crosslinking density due to its higher functionality (pentafunctional) than AETMS and MMTMS (trifunctional). Diamine-cured siliconized epoxy resins coupled with AETMS, MMTMS and MDTMS can be used for the development of high-performance advanced composites. |
