Adsorbent polymeric structures are described. These adsorbent polymeric structures are capable of separating non-polar hydrocarbons, such as crude oil or diesel fuel, from polar liquids, such as water. The adsorbent polymeric structures may include acid grafted graphene and at least one styrene. A method of preparing an adsorbent polymeric structure may include mixing graphene and at least one acid catalyst in a polar liquid in the presence of at least one alcohol to form an acid grafted graphene via an esterification reaction; and the acid grafted graphene and at least one styrene monomer are introduced to water in the presence of an initiator to form the adsorbent polymeric structure according to any of the previously-described embodiments via an emulsion polymerization reaction. Moreover, the adsorbent polymeric structures may be incorporated into methods of fluidly separating at least one non-polar hydrocarbon from a polar liquid.

Metal ion sequestering particles were formed in a one-pot single step synthesis by azeotropically removing water while heating a reaction mixture containing a branched poly(ethylenimine), poly(acrylic acid), di-(2-picolylamine), a catalytic amount of N,N-duimethylformamide, toluene, and either glycine or a carboxy-terminated poly(N-isopropylacrylamide). No other catalyst was present. The branched and crosslinked particles formed using the poly(N-isopropylacrylamide) sequestered metal ion from water at ambient temperature and released the bound metal ion upon heating.

The core-shell type amine-based carbon dioxide adsorbent including a chelating agent resistant to oxygen and sulfur dioxide according to the present invention is an adsorbent which includes a chelating agent to inhibit oxidative decomposition of amine and has, as a core, a porous support on which an amine compound is immobilized and has, as a shell, an amine layer resistant to inactivity by sulfur dioxide, and a method of preparing the same. The amine-based carbon dioxide adsorbent including a chelating agent exhibits considerably high oxidation resistance because an added chelate compound functions to directly remove a variety of transition metal impurities catalytically acting on amine oxidation. In addition, the sulfur dioxide-resistant amine layer of the shell selectively adsorbs sulfur dioxide to protect the amine compound of the core and, at the same time, the amine compound of the core selectively adsorbs only carbon dioxide. In addition, sulfur dioxide adsorbed on the shell is readily desorbed therefrom at about 110 C. and thus remarkably improved regeneration stability is obtained during the temperature-swing adsorption (TSA) process containing sulfur dioxide.

Polymeric sorbents for aldehydes including formaldehyde are provided. More particularly, the polymeric sorbents are a reaction product of a hydrolyzed divinylbenzene/maleic anhydride polymeric material having carboxylic acid groups with a nitrogen-containing compound having at least two primary amino groups and/or secondary amino groups. The nitrogen-containing compound is ionically attached to the hydrolyzed divinylbenzene/maleic anhydride within the polymeric sorbent and has at least one primary amino and/or secondary amino group available for reacting with an aldehyde. Additionally, methods of making the polymeric sorbents, methods of sorbing aldehydes (i.e., aldehydes that are volatile under use conditions) on the polymeric sorbents, compositions resulting from the sorption of aldehydes on the polymeric sorbents, composite granules containing the polymeric sorbents, methods of making the composite granules, and methods of sorbing aldehydes on the composite granules are provided.

The object of the present invention is polyphenylene oxide based film with crystalline nanoporous phases with surface area equal to or greater than 30 m2/g, preferably greater than 100 m2/g, and a procedure for the attainment thereof.

Microcapsules or macrocapsules have a core composition that includes a phase change material (PCM) encapsulated within a polymer wall with an outer shell having a siloxane tethered to an exterior surface of the polymer wall by a surfactant. The siloxane may form a crystalline or a sol-gel outer shell. Methods of making such capsules and textile fabrics and clothing incorporating such capsules include treating pre-formed capsules with a surfactant solution followed by treating with a compound containing a siloxane functional group. The surfactant connects or tethers the siloxane to the exterior surface of the polymer wall and the siloxane forms an outer shell of the capsules.
