Stimuli-responsive polymers applied to traditional textiles have received widespread attention. In this work, a new type of polymer-modified polyester fabric was prepared with interpenetrating polymer network (IPN) hydrogel. The IPN hydrogel comprised of poly (N-isopropylacrylamide) (PNIPAAm), silk sericin (SS), and silver nanoparticles (Ag NPs). The presence of the IPN hydrogel on the surface of fibers can change the wettability of polyester fabric, in response to temperature. The thermal behavior of IPN hydrogel was characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TG). DSC results indicated that the IPN hydrogel exhibits temperature-responsive behavior and the lower critical solution temperature (LCST) was around 32.9℃. The decomposition temperature of modified polyester fabric (400.5℃) was better than the original polyester fabric (335℃). TG results indicated that the polymer-modified fabric possessed higher thermal stability than the original polyester fabrics. The thermo-physiological comfort of modified polyester fabric was characterized by water contact angle and vertical wicking test. Above the LCST, the wettability of the polymer-modified polyester fabric would decrease because of the volume phase transition of IPN hydrogel. Moreover, the antibacterial activity of the modified temperature-sensitive fabric against Staphylococcus aureus and Escherichia coli was also investigated, and the antibacterial activity for both microorganisms exceeded 95%. This study provided a feasible route to fabricate the temperature-responsive textile with great antibacterial performance.

Fast Release

Fast temperature-responsive interpenetrating polymer network hydrogels based on soy protein and poly(N-isopropylacrylamide) (PNIPAAm) were prepared using the sodium bicarbonate (NaHCO3) solutions as the reaction medium. The structure and properties were characterized using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The bovine serum albumin (BSA) release behaviors and release mechanism were also investigated. The results show that the proposed hydrogels have high porous structures and have a fast release rate. The BSA release mechanism belongs to an anomalous transport and the Fickian contribution is dominant. The proposed hydrogels may have the potential applications in the field of biomedical materials such as in the controlled release of drugs.

Responsive Hydrogels

The interpenetrating polymer network of fast temperature-responsive hydrogels based on soy protein and poly(N-isopropylacrylamide) were successfully prepared using the sodium bicarbonate (NaHCO3) solutions as the reaction medium. The structure and properties of the hydrogels were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, differential scanning calorimetry and thermal gravimetric analysis. The swelling and deswelling kinetics were also investigated in detail. The results have shown that the proposed hydrogels had high porous structure, good miscibility and thermal stability, and fast temperature responsivity. The presence of NaHCO3 had little effect on the volume phase transition temperature (VPTT) of the hydrogels, and the VPTTs were at about 32?C. Compared with the traditional hydrogels, the proposed hydrogels had much faster swelling and deswelling rate. The swelling mechanism of the hydrogels was the non-Fickian diffusion. This fast temperature-responsive hydrogels may have potential applications in the field of biomedical materials.

Semi-interpenetrating polymer network (semi-IPN) gels have been synthesized using a hydrosilylation reaction of 1,3,5,7-tetramethylcyclotetrasiloxane (TMCTS) as a joint molecule, and a,w-nonconjugated dienes, 1,5-hexadiene (HD) or 1,9-decadiene (DD) as linker molecules in the presence of polystyrene (PS) as a liner polymers in toluene or cyclohexane. Network structure, mesh size and mesh size distribution, of the resulting semi-IPN gels was quantitatively characterized by means of a scanning microscopic light scattering (SMILS). The relaxation peaks derived from three kinds of structures were detected in the semi-IPN gels prepared in toluene by the SMILS analysis. One was derived from the mesh formed by TMCTS/a,w-nonconjugated dienes about 1-2 nm. Others were derived from transition networks about 20-150 nm and large clustered liner polymer chains about 700-2300 nm. Effect of concentration and molecular weight of the liner polymer on the network structure of the semi-IPN gels in toluene was investigated. The relaxation peaks derived from transition networks or random coils formed by aggregated PS chains were detected in the semi-IPN gels containing high concentration or high molecular weight PS. The semi-IPN gels containing PS were also prepared in cyclohexane as a poor solvent for PS at 40ºC, which was a higher temperature than the upper critical solution temperature (UCST = 34ºC) of PS in cyclohexane. The network structure of the semi-IPN gels was traced by SMILS on the cooling process. In the semi-IPN gel with the short linker molecule of HD, the relaxation peak derived from clustered PS chains was detected over the UCST. By contrast, the relaxation peak derived from transition network was observed in the semi-IPN gel with the long linker molecule of DD.

A series of semi-interpenetrating polymer network (semi-IPN) hydrogels based on N,N’-diethylacrylamide (DEA) and itaconamic acid (IAM) were synthesized by changing the molar ratio of linear copolymer P(DEA-co-IAM) and DEA monomer. Linear copolymer P(DEA-co-IAM) was introduced into a solution of DEA monomer to prepare pH-thermo dual responsive P(DEA-co-IAM)/PDEA semi-IPN hydrogels. The thermal gravimetric analysis (TGA) revealed that the semi-IPN hydrogel has a higher thermal stability than the conventional hydrogel, while the interior morphology by scanning electron microscopy (SEM) showed a porous structure with the pore sizes could be controlled by changing the ratio of linear copolymer in the obtained hydrogels. The oscillatory parallel-plate rheological measurements and compression tests demonstrated a viscoelastic behavior and superior mechanical properties of the semi-IPN hydrogels. Besides, the lower critical solution temperature (LCST) of the linear copolymers increased with the increase of IAM content in the feed, while the semi-IPN hydrogels increased LCSTs with the increase of linear copolymer content introduced. The pH-thermo dual responsive of the hydrogels was investigated using the swelling behavior in various pH and temperature conditions. Finally, the swelling and deswelling rate of the hydrogels were also studied. The results indicated that the pH-thermo dual responsive semi-IPN hydrogels were synthesized successfully and may be a potential material for biomedical, drug delivery or absorption applications. The further applications of semi-IPN hydrogels are being conducted.
