Abstract
Official abstract text for this publication.
A controlled release composite membrane comprising hydrophobic styrene-butadienestyrene block copolymer as hydrophobic continuous medium and hydrophilic functional agents incorporated within silica nanoparticles as hydrophilic dispersed medium and a preparation process of said membrane are described.
First claim
Opening claim text (preview).
The invention claimed is: 1. A controlled release composite membrane comprising: a hydrophobic styrene-butadiene-styrene block copolymer as a hydrophobic continuous medium, and Pickering emulsion droplets comprising at least one anti-icing agent surrounded and stabilized by a hydrophilic dispersed medium comprising hydrophobic silica nanoparticles. 2. The controlled release composite membrane of claim 1 , wherein the at least one anti-icing agent is potassium formate. 3. The controlled release composite membrane of claim 1 , wherein the hydrophilic dispersed medium comprises agar. 4. A process for preparing a controlled release composite membrane according to any of claim 1 , 2 or 3 comprising: incorporating the at least one anti-icing agent into the hydrophobic styrene-butadiene-styrene block copolymer as hydrophobic continuous medium to form a mixture; and stabilizing the mixture with the hydrophobic silica nanoparticles using a Pickering emulsion templating method.
