摘要：

Two procedures using a template-free synthesis of zeolites A and X were compared in an effort to assess how modification of the porous structure of zeolites with various ligands impacts the property of hydrophobicity. Modification with ligands such as octyltrichlorosilane (OTCS), dichlorodiphenylsilane (DCDPS), chlorotrimethylsilane (CTMS), hexamethyldisiloxane (HMDS) as well as with a combination of CTMS and HMDS, was performed. Both procedures led to the formation of water repellant materials. The hydrophobicity of zeolite A increased when zeolite A was modified with DCDPS and with OTCS. Zeolite X demonstrated superior hydrophobic properties when modified with all ligands, except with HMDS. Infrared spectroscopy (IR), macroscopic analysis, scanning electron microscopy (SEM), and thermogravimetric analysis (TGA) data are presented. (C) 2015 Elsevier Ltd. All rights reserved.
