Abstract
As an article of manufacture, a durable composite, which comprises in combination a glass bead, and a multifunctional polymeric substance which has a functionality capable of interacting with a species of interest, and a further functionality interacted with a functionality of said glass bead to adhere the substance to the glass, such that there is a decreased tendency of the agent toward removal from the composite by an aqueous medium; and a method of making same.
Claims11
As an article of manufacture, a substantially free-flowing composite which consists essentially of, in combination:
- a glass bead;
- and
- a multifunctional polymeric substance deposited on said glass bead, said substance having a first functionality capable of interacting with a species, wherein said first functionality is a moiety selected from the group consisting of sulfonate and carboxylate, and a second functionality interacted with said glass bead to form hydrophobic bonds which adhere the substance to the glass, wherein said second functionality is a moiety selected from the group consisting of epoxy radicals, N-methyol and silanol.
A substantially free-flowing composite particle which consists essentially of, in combination:
- a glass bead;
- and
- a multifunctional polymeric substance which has a first functionality capable of interacting with a species, wherein said first functionality is a moiety selected from the group consisting of sulfonate and carboxylate, and a second functionality interacted with said glass bead to form hydrophobic bonds which adhere the substance to the glass, wherein said second functionality is a moiety selected from the group consisting of epoxy radicals, N-methyol and silanol.
A multiplicity of durable composite particles, each of the particles consisting essentially of, in combination:
- a glass bead core;
- and
- a multifunctional polymeric substance deposited on said core, said substance having a first functionality capable of interacting with a species, wherein said first functionality is a moiety selected from the group consisting of sulfonate and carboxylate, and a second functionality interacted with said glass bead core to form hydrophobic bonds which adhere the substance to the glass bead, wherein said second functionality is a moiety selected from the group consisting of epoxy radicals, N-methyol and silanol;
- said multiplicity of particles being free-flowing.
A substantially free-flowing composition, which consists essentially of plurality of core glass beads, and deposited on said core glass beads a multifunctional polymeric substance which has a first functionality capable of interacting with a species, wherein said first functionality is a moiety selected from the group consisting of sulfonate and carboxylate, and a second functionality interacted with said core glass beads to form hydrophobic bonds which adhere the substance to the glass beads, wherein said second functionality is a moiety selected from the group consisting of epoxy radicals, N-methyol and silanol.
