“…3A), consistent with the size expected for individual glycopolymer chains in this molecular weight range in solution. 60,61 As the hydrodynamic diameters observed for (1) MAN with and without Nile red were close to the lower limit of detection for DLS, Taylor dispersion analysis (TDA) of (1) MAN was then carried out to obtain a more accurate estimation of its hydrodynamic size. TDA is an absolute method to determine the diffusion coefficients (D), and thus the hydrodynamic radii (R h ), of molecules in solution, 62,63 based on the dispersion of a solute plug through a uniform cylindrical tube under laminar Poiseuille flow.…”

“…Chemical modification is used to impart a deliberate change in the composition or structure of fabrics leading to an improvement in fibre properties [235,236]. In the pursuit to achieve durable antimicrobial finish with the natural biocide berberine (Figure 3), the surface of cotton fabric was modified with an anionic bridging agent to create electrostatic interactions with cationic natural dye, thereby enhancing the affinity of berberine to cotton fabric [132,237].…”

The antimicrobial finishing of textiles has attracted research attention lately due to demands for a healthy lifestyle. As a result, several synthetic and natural antimicrobial agents for textiles have been developed over the years. Recently research into antimicrobials agents of natural origin have become more popular due to their enormous therapeutic potential and effectiveness in the treatment of infectious diseases while mitigating the side effects of the synthetic antimicrobials. Research into these natural biocides for textiles has seen increasing consumers awareness for two reasons, namely the potential negative impact of synthetic biocides on health versus the benefits of natural biocides, and the increasing rate of microbial resistance to most natural biocides. The immense literature on natural biocides suggests the preparedness of the research community and industry in addressing the environmental and health challenges associated with synthetic antimicrobial agents in response to the new consumer demands. This review focuses on the advances in natural antimicrobial agents and various methods of their application. Literature suggest that natural antimicrobial agents have chalked some success in terms of efficacy and wash durability, with minimal effect on the tensile strength of fabrics.

Star‐shaped poly(2‐hydroxyethyl acrylate) (PHEA)6 polymers were synthesized using hexafunctional chain transfer agent (CTA) trithiocarbonate type via reversible addition‐fragmentation chain transfer (RAFT) polymerization. The (PHEA)6 polymers with dodecyl chain‐end were non‐water soluble. As the molecular weight increased, the polymers could disperse in water, forming large aggregates with a DH of 1027 to 525 nm. On the contrary, the (PHEA)6 polymers with the carboxylic acid group at the chain‐end were completely soluble in water. Then, (PHEA)6 polymers were chain extended with N‐isopropylacrylamide (NIPAM) to obtain poly(2‐hydroxyethyl acrylate)‐b‐poly(N‐isopropylacrylamide) (PHEA‐b‐PNIPAM) block copolymers. The dodecyl group strongly affects the aqueous solution properties of the copolymers even with a high PNIPAM content. Copolymers with dodecyl chain‐end were insoluble or partially soluble in water, forming large aggregates (0.5 mg/ml in distilled water). The copolymers with carboxylic acid end‐group were totally water soluble. The thermo‐responsive phase behavior of the star‐shaped block copolymers was studied, and for this purpose, it was necessary to remove the RAFT group containing the dodecyl tail. The intense turbidity observed in the aqueous dispersions of the corresponding copolymers made it challenging to determine the LCST accurately. The copolymers with a carboxylic end group were evaluated as is.
