A light scattering technique was used in this process in order to characterize the sizes and zeta potentials of a PNIPAm hydrogel with the change of temperature and subsequently to observe and record ...

“We developed the loofah-inspired PNIPAm hydrogel by free radical polymerization using the mixed solvent as the polymerization medium,” explains Xu. “We then functionalized the PNIPAm with PDA and ...

One solution could be temperature-responsive hydrogels, specifically poly(N-isopropyl acrylamide) (PNIPAm), that switch from absorbing water at cooler temperatures to repelling it when heated.

Through a series of characterizations of γ-FeOOH microgel and γ-FeOOH/KGM(Ga)/PNIPAM thermosensitive hydrogel, it is demonstrated that the composite thermosensitive hydrogel has been ...

This combination of the hygroscopic polymer and PNIPAM resulted in what the Yu group calls a super moisture-absorbent gel (SMAG) (Adv. Mater. 2019, DOI: 10.1002/adma.201806446). At 90% relative ...

“Crucially, the required weight for our optimized system, the 15 wt.% PNIPAM/PAM semi-IPN hydrogel, was only 5.14 kg m2, which is 80%-85% lower when compared to other examples,” said the ...

A study published in materials demonstrated that amino functionalized boron nitride nanosheets/poly(N-isopropyl acrylamide) (NH 2-BNNS/PNIPAM) hydrogel has high absorption capacity for hydrophilic ...

(Courtesy: Z Zhu et al Sci. Advances doi: 10.1126/sciadv.adh2213) The researchers formed the microneedle patch from a mixture of silk fibroin and the hydrogel pluronic F127 (silk-Fp), adding ...
