“…Recently, water-soluble nonionic polymers and their hydrogels have attracted much attention due to their scientific and technological importance. The interaction between hydrogels and surfactant as one of the focused points has been extensively studied. − It was found that some hydrogels could effectively concentrate surfactant molecules inside the gel networks and underwent a large volume change when the temperature increased. The adsorption of surfactant molecules into a gel network could also induce an extra swelling.…”

Narrowly distributed spherical poly(N-vinylcaprolactam) (PNVC) microgels were prepared by precipitation polymerization in water. The effect of both anionic (sodium dodecyl sulfate, SDS) and cationic (N-dodecylpyridinium bromide, DPB) surfactants on the swelling and shrinking of the microgels were investigated by laser light scattering (LLS). Our results showed that the microgels gradually shrank to the collapsed state when the temperature increased from 20 to ∼38 °C. The addition of anionic surfactant caused an extra swelling of the microgels and shifted the collapsing temperature higher, whereas the addition of cationic surfactant has different effects on the swelling and shrinking of the microgels prepared by using different initiators, depending on whether the decomposed fragments of the initiator are ionic or neutral. Our results clearly showed that the ionic groups introduced into polymer gels from the initiators should be taken into consideration in the study of the surfactant/gel interaction.

“…105,106 ELPs have drawn interest as thermally responsive biopolymers due to their lower critical solution temperature (LCST) phase behavior in water 107 and resemblance to the well-studied LCST polymer poly(N-isopropylacrylamide). 108 ELPs are soluble in water below the LCST transition temperature (T t ), which is often referred to as the cloud point temperature. 109 When raising the temperature above T t , ELPs undergo reversible phase separation from water (Figure 2A).…”

Protein-based polymers possess chemically defined sequences that can encode diverse properties and functions into a new class of biopolymeric materials.However, sequence variation that emerges from evolution can obscure the sequence-function relationships of naturally derived polymers. One strategy to clarify these relationships is to identify common sequences between proteins with similar functions. These conserved sequences often emerge from repeat proteins, and "consensus repeat sequences" provide a convenient platform for systematic investigations of biopolymer sequence-property relationships. In this review, we highlight recent approaches to engineer tunable polymeric materials using monomer-scale design of consensus repeat proteins. We explore established and emerging protein-based materials with mechanical resilience, thermodynamic phase behavior, chemical responsiveness, biomolecular transport, and hierarchical structure. Overall, recent advances in the monomer-scale design of repetitive protein polymers present exciting fundamental and translational opportunities for polymer scientists and engineers.

“…365,366 The influence of surfactants on the phase transitions in polymers with amino acid side groups has been investigated. 367 The antitumour preparation 9-b-D-arabinofuranosyladenine (Ara-A) was immobilised in a thermosensitive gel based on the copolymer of 2-hydroxyethyl methacrylate, styrene, and the methyl ester of acryloyl-L-proline cross-linked by nonaethylene glycol dimethacrylate. The gel was obtained by radiation-induced copolymerisation.…”
