Abstract:

A new class of surface modified particles and a multi-step Michael-type addition surface modification process for the preparation of the same is provided. The multi-step Michael-type addition surface modification process involves two or more reactions to compatibilize particles with various host systems and/or to provide the particles with particular chemical reactivities. The initial step comprises the attachment of a small organic compound to the surface of the inorganic particle. The subsequent steps attach additional compounds to the previously attached organic compounds through reactive organic linking groups. Specifically, these reactive groups are activated carbon—carbon pi bonds and carbon and non-carbon nucleophiles that react via Michael or Michael-type additions.

Abstract:

The present invention relates to a new class of surface modified particles and to a multi-step surface modification process for the preparation of the same. The multi-step surface functionalization process involves two or more reactions to produce particles that are compatible with various host systems and/or to provide the particles with particular chemical reactivities. The initial step comprises the attachment of a small organic compound to the surface of the inorganic particle. The subsequent steps attach additional compounds to the previously attached organic compounds through organic linking groups.

Abstract:

This invention provides composite materials that combine the material properties of hydrophobic polymers with internal structure and order provided by polymerization of lyotropic liquid crystals (LLCs). Composites, particularly nanocomposites, are made by forming a LLC assembly that has hydrophobic regions and hydrophilic regions, combining hydrophobic polymer in the assembly and polymerizing the polymerizable LLC monomers in the assembly. The hydrophobic polymer, polymerized LLC assembly or both can be crosslinked in the composite. Nanoporous composites, particularly those with uniform-sized pores and/or with uniform pores distribution can be prepared in this way. In addition, complex polymers in which a second polymeric material, which may be organic or inorganic, can be introduced into the pores or other structural features of the composite can be prepared. Adding flexible hydrophobic polymers to the LLC assembly increases the flexibility and toughness of the resultant polymerized composite material to provide improved composite materials for use as membranes and in other applications. Hydrophobic polymer addition can also increase the diffusion resistance in the organic phase of the composite.

Abstract:

Surface-modified nanoparticles of boehmite, and methods for preparing the same. Aluminum oxyhydroxide nanoparticles are surface modified by reaction with selected amounts of organic acids. In particular, the nanoparticle surface is modified by reactions with two or more different carboxylic acids, at least one of which is an organic carboxylic acid. The product is a surface modified boehmite nanoparticle that has an inorganic aluminum oxyhydroxide core, or part aluminum oxyhydroxide core and a surface-bonded organic shell. Organic carboxylic acids of this invention contain at least one carboxylic acid group and one carbon-hydrogen bond. One embodiment of this invention provides boehmite nanoparticles that have been surface modified with two or more acids one of which additional carries at least one reactive functional group. Another embodiment of this invention provides boehmite nanoparticles that have been surface modified with multiple acids one of which has molecular weight or average molecular weight greater than or equal to 500 Daltons. Yet, another embodiment of this invention provides boehmite nanoparticles that are surface modified with two or more acids one of which is hydrophobic in nature and has solubility in water of less than 15 by weight.

Abstract:

The present invention provides block copolymers containing at least one block of a poly(heteroaromatic) polymer and at least two blocks of a non-conjugated polymer. The chemically different blocks of the copolymer are covalently bonded to each other in an alternating fashion through an appropriate linkage group. The poly(heteroaromatic) block may exist in its neutral or oxidized form, and when in the oxidized form, it associates with organic or inorganic counter-anions to balance the charge. The poly(heteroaromatic) polymer is an intrinsically conducting polymer (ICP), and when in the oxidized form it is electrically conducting. When the ICP block or blocks of the block copolymer are in the doped form, the block copolymer is electrically conducting. Preferably the conducting block copolymers have conductivities in the range 10-10S/cm. Block copolymers of this invention are soluble or dispersible in water, one or more organic solvents, or in a mixture thereof at a level of at least about 0. 1 g/liter.
