Three different methods were used to make these comparisons. The polarized microscope (POM) method was used to observe and compare morphological changes. It was observed that the texture structures of the lyotropic lamellar phases obtained by using anionic and cationic surfactants were different from each other. Structural changes were investigated by the small-angle X-ray scattering (SAXS) method. As the polymer concentration added to the lyotropic lamellar phase(s) increased, it was determined that the structural changes of the anionic and cationic samples were different from each other. While the polymer added to the anionic surfactant compresses the structure, the polymer added to the cationic surfactant does not significantly alter the structural parameters. The interactions of surfactant-polymer molecules with each other and their packaging were accordingly investigated by Fourier transform infrared spectroscopy (FTIR). How the polymer was added to the lyotropic lamellar phase and how the surfactant interacted with the chain and head groups was determined by examining the frequency shifts of the methylene chains and head groups. These frequency shifts provide information about trans-gauche transformations. The results indicate that the polymer added to both groups leads to a transition towards a gauche conformation. Both polymers and lyotropic lamellar phases have wide biological and technological uses. For this reason, their use together, that is, the interactions of polymer doped-lamellar phases, is interesting and should be understood.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"303 2","pages":"301 - 312"},"PeriodicalIF":2.2,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143108701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several analytical methods, including FT-IR, XRD, SEM, DSC, and mechanical testing, were used to evaluate the modifications and properties of the composites. FT-IR confirmed successful chitosan incorporation into the ER-PA composites, supported by SEM analysis showing improved structural integrity.

The study aims to address the limitations of PTX, such as poor water solubility and drug resistance in cancer cells, by combining it with CUR, known for its anti-cancer properties and ability to inhibit drug resistance mechanisms. The FA-Ge-P407 nanogel was synthesized through a multi-step process involving the conjugation of folic acid (FA) onto a gelatin-Poloxamer P407 copolymer, which was characterized by FT-IR and HNMR spectroscopy. The nanogel particles were designed to encapsulate PTX and CUR, with their size, surface charge, and morphology thoroughly characterized using TEM and DLS techniques. In vitro release studies demonstrated that the presence of CUR enhanced and sustained PTX release, particularly under acidic conditions. The cytotoxicity assessment on MCF-7 breast cancer cells indicated that the FA-Ge-P407/PTX/CUR formulation exhibited superior anticancer activity compared to free PTX and FA-Ge-P407/PTX alone. The results suggest that FA-Ge-P407 nanogels offer a promising strategy for targeted breast cancer therapy, leveraging the combined effects of PTX and CUR to overcome drug resistance and achieve sustained therapeutic outcomes.

The influence of polymerizable surfactants mixed with conventional anionic surfactant and semi-batch seeded emulsion polymerization on the colloidal stability, particle size, zeta potential, electrolyte stability, water absorption of the polymer films, wet scrub resistance, and water absorption of the paint films were investigated. The contribution of semi-batch seeded operating conditions on the colloidal stability of poly(St/BA/AA/AM) latexes and on the waterborne paints was studied. The results showed a significant improvement in the latex stability against coagulation and end-use properties when compared to unseeded latex. The use of semi-batch seeded emulsion polymerization enhanced the application properties of the latex and paints based on the polymerizable surfactant mixtures. When polymerizable surfactant was used together with conventional anionic surfactant in semi-batch seeded conditions, stable latexes, particle sizes ranging from 105 to 130 nm, and better scrub resistance of the paint films were obtained. The use of polymerizable surfactants helps to reduce the total amount of surfactant in the latex recipe. Furthermore, the use of semi-batch seeded conditions helps in the control of particle size, coagulum content, electrolyte stability of the latexes, and increased wet scrub resistance of the paint films. The use of a seed latex prepared in situ provides additional insights for the production of poly(St/BA/AA/AM) latexes characterized by an increase in both colloidal stability and wet scrub resistance of the paint films.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"303 2","pages":"247 - 260"},"PeriodicalIF":2.2,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143110049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, HAMP was endowed with amphiphilic properties and thermo-associate behavior by introducing surfactant monomer and hydrophobic groups, respectively. Thus, HAMP has the potential for synergies with surfactant due to their amphiphilic properties and exhibits thermo-thickening behavior due to the thermo-associate behavior. These two properties are applied to the removal of oil-based drilling fluids and to increase the stability of spacers. Tests shows that: HAMP can synergize with ionic/non-ionic surfactant to increase the interface activity of surfactant/HAMP mixture; HAMP solution exhibits continuous thermo-thickening behavior at temperature above 70 °C when its concentration is higher than 0.3%, which can mitigate the consistency reduction of spacers at high temperature; the surfactant/HAMP mixture has higher removal efficiency and better temperature and salt resistance than the single surfactant solution; rheological property changes little in the range from 25to 90 ℃, and 0.3% HAMP can prevent the sedimentation of weighted spacer. Series of mechanism experiments indicate that more association forms a denser micronetwork at higher temperature, which leads to the thermo-thickening behavior of HAMP; the groups with different charges and hydrophobic groups in HAMP can make it better adsorbed on the surface and the components the oil-based filter cake, resulting in wetting modification of the surface and stabilizing oil-base components, which are conducive to the removal of the oil-based drilling fluid.

By unidirectionally transporting the saline, the AGA not only shows stable steam generation but also generates continuous electricity due to the formation of an asymmetric electric double-layer. For seawater desalination, the evaporation rate reaches about 2.82 kg m⁻² h⁻¹ under one sun irradiation. And the evaporation performance has no obvious attenuation after long-term usage due to self-operating salt rejection. During the seawater evaporation, the AGA can generate output voltage of ca. 0.85 V and short-circuit current of 0.01 mA. The AGA has the advantages of strong light absorption, high photothermal conversion ability, low thermal conductivity, low-cost, excellent salt rejection ability, making it very attractive for practical applications.

This research utilizes hydrogen bonding between amide groups to design molecular models of polynorbornene derivatives (PNbs). The PNbs are abbreviated as Pm-8, where “m” indicates the amount of methylene groups as spacers in the side chain, and “8” refers to the oxyoctyl tail. The aim is to obtain a gradual variation of inter- and intra-chain interplay for further elucidation. Based on an analysis of spatial descriptors, mean square displacement (MSD), and radial distribution function (RDF) by using molecular mechanics (MM) and molecular dynamics (MD) methods, it is found that the asymmetry of side chains plays a more significant role in determining micro-structural regularity than the length. Highly asymmetric side chains are favorable for forming inter-chain hydrogen bonding, promoting interdigitation, and creating a larger scale of regularity in P8-8 and P10-8 molecules. In contrast, the relatively symmetric side chains tend to form intra-chain bonding, resulting in limited regularity within P2-8 and P4-8 molecules. Therefore, unlike regular structures that usually require symmetrical molecules, polynorbornene derivatives with asymmetric side chains have achieved highly ordered orthorhombic lattices in experiments.
