摘要： Disclosed herein is a sequential functionalization methodology for the covalent modification of nanotubes with between one and four repeat units of a polymer. Covalent attachment of oligomer units to the surface of nanotubes results in oligomer units forming an organic sheath around the nanotubes, polymer-functionalized-nanotubes (P-NTs). P-NTs possess chemical functionality identical to that of the functionalizing polymer, and thus provide nanoscale scaffolds which may be readily dispersed within a monomer solution and participate in the polymerization reaction to form a polymer-nanotube/polymer composite. Formation of polymer in the presence of P-NTs leads to a uniform dispersion of nanotubes within the polymer matrix, in contrast to aggregated masses of nanotubes in the case of pristine-NTs. The covalent attachment of oligomeric units to the surface of nanotubes represents the formation of a functional nanoscale building block which can be readily dispersed and integrated within the polymer to form a novel composite material.

摘要： An embodiment of a microcapsule includes a shell surrounding a space, a liquid within the shell, and a light absorbing material within the liquid. An embodiment of a method of making microcapsules includes forming a mixture of a light absorbing material and an organic solution. An emulsion of the mixture and an aqueous solution is then formed. A polymerization agent is added to the emulsion, which causes microcapsules to be formed. Each microcapsule includes a shell surrounding a space, a liquid within the shell, and light absorbing material within the liquid. An embodiment of a method of using microcapsules includes providing phototriggerable microcapsules within a bulk material. Each of the phototriggerable microcapsules includes a shell surrounding a space, a chemically reactive material within the shell, and a light absorbing material within the shell. At least some of the phototriggerable microcapsules are exposed to light, which causes the chemically reactive material to release from the shell and to come into contact with bulk material.

摘要： Porous polymer monoliths are made thermally responsive by functionalizing/grafting the pores with thermally responsive polymers and copolymers. Depending on the reaction conditions employed, the grafted polymer can either completely block flow through micrometer-sized pores in the monoliths or control the flow rate through the monoliths. The grafted monoliths are useful as thermal gates, thermal valves, and for isocratic hydrophobic interaction chromatography of proteins.

摘要： Disclosed are a method and apparatus for converting light energy to mechanical energy by modification of surface tension on a supporting fluid. The apparatus comprises an object which may be formed as a composite object comprising a support matrix and a highly light absorptive material. The support matrix may comprise a silicon polymer. The highly light absorptive material may comprise vertically aligned carbon nanotubes (VANTs) embedded in the support matrix. The composite object is supported on a fluid. By exposing the highly light absorptive material to light, heat is generated, which changes the surface tension of the composite object, causing it to move physically within the fluid.

摘要： Novel main chain acid degradable polymer backbones and drug delivery systems comprised of materials capable of delivering bioactive materials to cells for use as vaccines or other therapeutic agents are described. The polymers are synthesized using monomers that contain acid-degradable linkages cleavable under mild acidic conditions. The main chain of the resulting polymers readily degrade into many small molecules at low pH, but remain relatively stable and intact at physiological pH. The new materials have the common characteristic of being able to degrade by acid hydrolysis under conditions commonly found within the endosomal or lysosomal compartments of cells thereby releasing their payload within the cell. The materials can also be used for the delivery of therapeutics to the acidic regions of tumors and other sites of inflammation.

摘要： Compositions and methods of making a modified polyhydroxylated polymer comprising a polyhydroxylated polymer having reversibly modified hydroxyl groups, whereby the hydroxyl groups are modified by an acid-catalyzed reaction between a polydroxylated polymer and a reagent such as acetals, aldehydes, vinyl ethers and ketones such that the modified polyhydroxylated polymers become insoluble in water but freely soluble in common organic solvents allowing for the facile preparation of acid-sensitive materials. Materials made from these polymers can be made to degrade in a pH-dependent manner. Both hydrophobic and hydrophilic cargoes were successfully loaded into particles made from the present polymers using single and double emulsion techniques, respectively. Due to its ease of preparation, processability, pH-sensitivity, and biocompatibility, of the present modified polyhydroxylated polymers should find use in numerous drug delivery applications.

摘要： A broadly applicable method requiring no more than a single step facilitates the preparation of large area super hydrophobic or super hydrophilic surfaces on a variety of substrates such as such as glass, metal, plastic, paper, wood, concrete and masonry. The technique involves the free radical polymerization of common acrylic or styrenic monomers in the presence of porogenic solvents in a mold or on a free surface. The material can be semi- or fully-transparent and either super hydrophobic or super hydrophilic depending on the choice of the monomers. Because porosity and dual scale roughness are intrinsic bulk properties of the monolithic materials and not only a surface characteristic, the polymers can be powdered to produce a super hydrophobic powder or otherwise fragmented and attached to the surface of any object to render it super hydrophobic or super hydrophilic. The surface properties of the porous material may also be altered locally by photografting with selected monomers.
摘要翻译：广泛应用的方法不需要单一步骤便于在各种基材如玻璃，金属，塑料，纸，木材，混凝土和砖石上制备大面积超疏水或超亲水表面。该技术涉及常规丙烯酸或苯乙烯类单体在造孔溶剂存在下在模具中或自由表面上的自由基聚合。根据单体的选择，该材料可以是半透明的或完全透明的，并且是超疏水的或超亲水的。由于孔隙率和双重尺度粗糙度是整体材料的固有本体特性，不仅表面特性，聚合物可以被粉末化以产生超疏水性粉末，或以其他方式分散和附着到任何物体的表面，使其超疏水或超级亲水的。多孔材料的表面性质也可以通过用选择的单体进行光刻而局部改变。
