Fabricating ternary hydrogels of P(AM-co-DMAEMA)/PVA/ β -CD based on multiple physical crosslinkage

Highly Strong and Transparent Ionic Conductive Hydrogel as Multifunctional Sensors

“…The embedded β‐CD inside PVA hydrogel matrix will affect the partial PVA chains form crystallites, but will generate multiple hydrogen bonds to offset the loss of mechanical strength. [ 29 ] Finally, because of the osmotic pressure difference between the SN‐hydrogels and the PAA/KCl solution, a transparent and ionic conductive DN‐hydrogels with high mechanical property can be fabricated after soaking SN‐hydrogels in PAA/KCl solution. It was reported that the short PAA chains (low molecule weight, M w ≈ 3000) can diffuse into the PVA/β‐CD hydrogel until reach an equilibrium and realize a homogeneous distribution.…”

“…[ 31,32 ] The XRD curves showed the visible changes of characteristic peaks compared to PVA hydrogels, indicating that the embedding of high‐crystallization β‐CD molecule and amorphous PAA short chains would affect the crystallinity of the ionic conductive hydrogels (Figure S3, Supporting Information). [ 29,30 ] In addition, SEM images showed the variations of distinct network structure for different DN‐hydrogels. The results illustrated that appropriate β‐CD contents could facilitate the formation of hydrogel with uniform and firm networks (Figure S4, Supporting Information).…”

The investigation of the specific behavior of a cationic block structure and its excellent flocculation performance in high-turbidity water treatment

“…8 shows the TGA thermographs of the polymers, in which three stages of weight loss were observed. The loss of absorbed moisture in the polymers (CPAA: 10.1 wt%, TPAA: 9.9 wt%) occurred within the temperature range of 30-195 C. 43 The thermal decomposition of the imine in the amide groups (CPAA: 18.9 wt%, TPAA: 18.1 wt%) occurred between the temperatures of 195 and 350 C. 44 Carbonization of the polymeric backbone and the decomposition of N + -(CH 3 ) 3 groups (CPAA: 52.5 wt%, TPAA: 53.7 wt%) were observed in the range of 350-520 C. 45 Obviously, double hump-like heat absorption peaks (383.6 and 417.1 C) were observed for TPAA, whereas only one absorption peak (421.1 C) was observed for CPAA. Because there were two different structural blocks (ATAC and AM blocks) in the TPAA polymer chain, their decomposition generated two different heat absorption peaks.…”

Inclusion Complex of Docetaxel with Sulfobutyl Ether β-Cyclodextrin: Preparation, In Vitro Cytotoxicity and In Vivo Safety

“…Insoluble drugs should be made dissolvable by physico-chemical or biological means in order to arrive at the pharmacological target in appreciable amounts. Various approaches exemplified by the addition of co-solvents [ 1 , 2 , 3 ], solid dispersion [ 4 ], size reduction [ 5 , 6 ], as well as the complexation with cyclodextrins(CD) [ 7 ], have been used to optimize the solubility of insoluble substances.…”
