POLYMER MATERIALS FOR DELIVERY OF SHORT-CHAIN FATTY ACIDS TO THE INTESTINE FOR APPLICATIONS IN HUMAN HEALTH AND TREATMENT OF DISEASE

Provided herein are polymer materials that find use in, for example, delivery of short-chain fatty acids. In particular, polymers are provided that form stable nanoscale structures and release their payload, for example, by cleavage of a covalent bond (e.g., via hydrolysis or enzymatic cleavage). The polymers are useful, for example, for delivery of payloads (e.g., SCFAs) to the intestine for applications in health and treatment of disease, and have broad applicability in diseases linked to changes in the human microbiota including inflammatory, autoimmune, allergic, metabolic, and central nervous system diseases, among others.

Solid-state, individual dispersion of single-walled carbon nanotubes in ionic liquid-derived polymers and its impact on thermoelectric properties

The structure of carbon nanotubes and their electronic interaction with a matrix are important for extracting the unprecedented electronic properties, which have yet to be explored. Here we investigate the dispersibility of single-walled carbon nanotubes (SWNTs) in ionic liquid-derived polymers (PILs), revealed by cross-sectional transmission electron microscopy, infrared optical spectroscopy, and Raman spectroscopy. Surprisingly, SWNTs studied here are highly dispersed, at least down to 7.5 nm-fibres, in a trimethylammonium-suspended PILs. Based on this discovery, we found that the well-dispersed and almost fully dispersed SWNTs in PILs are responsible for the enhanced thermoelectric properties, a future energy harvesting technique.

A strategy for enhanced antibacterial activity against Staphylococcus aureus by the assembly of alamethicin with a thermo-sensitive polymeric carrier

We demonstrate here a strategy for enhanced antibacterial activity against microbial strains by the assembly of antimicrobial peptides with a temperature-responsive polymeric carrier. The assembly complex was less toxic to human cells and more stable to enzymatic cleavage. This work may provide a promising drug delivery system for antimicrobial peptides.

Preparation and functionalization of linear and reductively degradable highly branched cyanoacrylate-based polymers

Ethyl cyanoacrylate (ECA) was polymerized radically in the presence of small amounts of trifluoroacetic acid as effective inhibitor of incidental anionic polymerization. Methyl methacrylate and other functional vinyl monomers (e.g., 2-chloroethyl and 2-bromoethyl methacrylate) were copolymerized with ECA, yielding linear ECA-rich copolymers, which could readily undergo further modifications, for instance nucleophilic substitution with azide. In the presence of a disulfide-containing dimethacrylate crosslinker and a chain transfer agent (CBr4) during the free radical copolymerizations of ECA with methacrylates, highly branched ECA-based polymers containing disulfide groups at the branching points were obtained prior to gelation. The polymers degraded upon addition of reducing agents. The prepared polymers, which contained peripheral (chain end) alkyl bromide groups as well as pendant alkyl chloride or bromide groups were then reacted with sodium azide, affording azide-containing polymers that were reacted with functional alkynes under copper-catalyzed “click” chemistry conditions.

Controlled synthesis of photosensitive graft copolymers with high azobenzene-chromophore loading densities in the main and side chains by combining ATRP and ADMET polymerization

Photosensitive graft copolymers containing azobenzene chromophores in the main and side chains were successfully synthesized by combining living atom transfer radical polymerization (ATRP) and acyclic diene metathesis (ADMET) chemistry based on the results of proper heterodifunctional inimer and azobenzene monomer design. The precise copolymer architectural features were manipulated by combining the macromonomer technique and the macroinitiator method. The as-prepared copolymer containing azobenzene chromophores in the main and side chains showed unique reversible isomerization processes, suggesting that the photoisomerization of azobenzene chromophores occured mainly in one of the two types of azobenzene groups in the main or side chains with similar probabilities due to their main and side-on structure.

Imidazolium-based poly(ionic liquid)s as new alternatives for CO 2 capture

Solid imidazolium-based poly(ionic liquid)s with variable molecular weights that contain the poly[2-(1-butylimidazolium-3-yl)ethyl methacrylate] (BIEMA) cation and different counter anions were evaluated in terms of CO2 capture and compared with classical ionic liquids with similar counter anions. In addition to poly(ionic liquid)s with often-applied ions such as BF 4-, PF6-, NTf2 -, trifluoromethanesulfonate (OTf-) and Br-, for the first time [BIEMA][acetate] was synthesised, which revealed a remarkably high CO2 sorption performance that exceeded the poly(ionic liquid)s studied previously on average by a factor of four (12.46 mg gPIL -1). This study provides an understanding of the factors that affect CO2 sorption and a comparison of the CO2 capture efficiency with the frequently used sorbents. Moreover, all the studied sorbents were reusable if regenerated under carefully selected conditions and can be considered as suitable candidates for CO2 sorption. Pretty poly(ionic liquid)s! Solid poly(ionic liquid)s that contain the poly[2-(1- butylimidazolium-3-yl)ethyl methacrylate] cation and different anions, in particular a new combination with the acetate anion, are evaluated for CO 2 capture and demonstrated to be alternative CO2 sorption materials.

Anion exchanged polymerized ionic liquids: High free volume single ion conductors

In this study, we investigate the isolated effect of anion type on the chemical, thermal, and conductive properties of imidazolium-based polymerized ionic liquids (PILs). PILs with various anions at constant average chain length were prepared by ion exchange with a water-soluble PIL precursor, (poly(1-[(2-methacryloyloxy)ethyl]-3-butylimidazolium bromide) (poly(MEBIm-Br)). NMR, IR, and elemental analysis confirm that anion exchange of ploy(MEBIm-Br) with bis(trifluoromethanesulfonyl) imide (TFSI), tetrafluoroborate (BF 4), trifluoromethanesulfonate (Tf), and hexafluorophosphate (PF 6) in water resulted in nearly fully exchanged PILs. As a function of anion type, the glass transition temperature plays a dominant role, but not the sole role in determining ion conductivity. Other factors affecting ionic conductivity include the size and symmetry of the anion and dissociation energy of the ion pair. Both the Vogel-Fulcher-Tammann (VFT) and Williams-Landel-Ferry (WLF) equations were employed to investigate the temperature dependent ionic conductivities. The C1g (9.03) and C2g (168 K) values obtained from the WLF regression of these PILs greatly deviate from the classical WLF values originally obtained from the mechanical relaxation of uncharged polymers (C1g = 17.44, C2g = 51.6 K) and the WLF values obtained from the conductive properties of other polymer electrolytes. This suggests that the fractional free volume (f (Tg) = B/(2.303C1g)) and Vogel temperature (T0 = T g - C2g) are strong functions of ion concentration, where high free volume allows for ion mobility at temperatures farther below the glass transition temperature of the polymer.
