•Porous membranes are obtained with poly(vinyl alcohol) (72% degree of hydrolysis).•Spinodal and cloud point curves are very close suggesting spinodal decomposition.•Cross-linking reaction appears to be a key step for the membrane structuration.•The control of the relative humidity affects the porosity of the top skin layer.

The mono-6-deoxy-6-azides of 2,6-di-O-methyl-β-cyclodextrin (DIMEB) and randomly methylated-β-cyclodextrin (RAMEB) were conjugated to propargylated hydroxyethyl starch (HES) by Cu(+)-catalysed [2 + 3] cycloaddition. The resulting water soluble polymers showed lower critical solution temperatures (LCST) at 52.5 °C (DIMEB-HES) and 84.5 °C (RAMEB-HES)...

Interpenetrating polymer networks (IPN) hydrogels have gained great attention in the last decades, mainly due to their biomedical applications. This review aims to give an overview of the recent design concepts of IPN hydrogels and their applications in controlled drug delivery, and separation processes. In the first part, the main strategies for t...

Thermoresponsive polymers have been the subject of numerous publications and research topics in the last few decades mostly driven by their easily controllable temperature stimulus and high potential for in vitro and in vivo applications. P(NIPAAm) is the most studied amongst these polymers, but recently other types of polymers are increasingly bei...

Each year millions of people sustain traumatic or surgical wounds, which require proper closure. Conventional closure techniques, including suturing and stapling, have many disadvantages. They inflict additional damage on the tissue, elicit inflammatory responses and have a relatively long application time. Especially for the more demanding wounds,...

The host-guest complex of dipropoxypillar[5]arene and an ionic liquid 1,3-dimethylimidazolium iodide is found to exhibit a lower critical solution temperature (LCST)-type phase transition in chloroform. This LCST-type phase behavior can be conveniently modulated by experimental parameters and can be easily combined with the ionic liquid for potenti...

Poly(N-isopropylacrylamide-co-N-hydroxyethylacrylamide) (poly(NIPAAm-co-HEAAm)) was prepared as a new thermosensitive copolymer possessing a sharp phase transition around the human body temperature. The effect of the copolymer concentration on the lower critical solution temperature (LCST) was determined under physiological conditions by cloud poin...

Polymer hydrogels have been widely explored as therapeutic delivery matrices because of their ability to present sustained, localized and controlled release of bioactive factors. Bioactive factor delivery from injectable biopolymer hydrogels provides a versatile approach to treat a wide variety of diseases, to direct cell function and to enhance ti...

Layered silicate clays are natural crystallites and are well recognized for their structures and industrial applications, but there are very few reports on their structural confinement properties and on the mechanisms that underlie their polymer interactions. In this review, we summarize the recent progress on clay modification via conventional ion...
