This review covers the recent advances in studies of the volume phase transition and critical
phenomena of polymer gels mostly carried out in our group from 1973 to the present. We …

Topological entanglement in polymers and biopolymers is a topic that involves different
fields of science such as chemistry, biology, physics, and mathematics. One of the main …

The small angle neutron scattering experiments were conducted on N‐isopropyl acrylamide
(NIPA) gels in D2O and on the corresponding NIPA solutions. The NIPA gels underwent a …

We discuss the elastic modulus G and swelling/deswelling behavior of networks as a
function of their concentration< t> and their preparation state. Simple scaling ideas …

The phase transition of gels containing N-isopropylacrylamide (NIPA) was investigated by
differential scanning calorimetry (DSC) and swelling measurements. The enthalpy of …

The coil-to-globule transition of individual poly (N-isopropylacrylamide)(PNIPAM) linear
chains and the volume phase transition of spherical PNIPAM microgels were studied by a …

Responsive hybrid colloids containing both organic and inorganic components have been
the subject of many investigations in recent years. These new materials combine the stimuli …

Concentration fluctuations in polymer gels are composed of dynamic thermal fluctuations
and frozen inhomogeneities. Particularly, the latter is a characteristic of gels and is due to …

There have been more challenges for hydrogel actuators to meet the combined requirement
of discoloration, complex deformation, and simple preparation. Structural coloration is widely …

Poly (N-isopropylacrylamide-co-acrylamide-co-maleic acid)(P (NIPAM-AM-MA)) hydrogel
has been synthesized by free radical polymerization. The incorporation of functional …
