“…It can also be formed if the radical attacks double bonds pendant on other chains already chemically connected with the growing radical [25]. A similar behavior was observed during the swelling studies reported for poly(Nvinyl-2-pyrrolidone/itaconic acid) and poly(acrylamide/maleic acid) hydrogel systems [26].…”

“…Since it does not require additives, the generated structures are capable of sterilization and free of carcinogenic materials. [32][33][34] Because of these advantages, the radiation-induced crosslinking can be one of the most attractive fabrication methods. Gamma rays have been employed to crosslink the gelatin-based hydrogels.…”

Gelatin-based hydrogels derived from hydrolysis of collagen have been extensively used in pharmaceutical and medical applications because of their biocompatibility and biodegradability. For example, gelatin-based hydrogels are finding use in drug delivery and tissue engineering because they are able to promote cell adhesion and proliferation. In addition, these hydrogels can be used as wound dressings due to their attractive fluid absorbance properties. Manufacturing technologies such as ultraviolet stereolithography and two-photon polymerization can be used to prepare structures containing photosensitive gelatin-based hydrogels. This review describes the preparation of gelatin-based hydrogels and use of these materials for biomedical applications.

“…Crosslink density of the networks was determined using equilibrium swelling data according to the Flory-Rehner equation [21,24]. The equilibrium degree of swelling (Q), which is the reciprocal of volume fraction of polymer in swollen state (V p ), was calculated based on the swelling data of the samples in various solvents using the following equations:…”

Hydroxyl functionalized nano-sized POSS or ethyleneglycol as diol monomers was incorporated to hydroxyl-terminated polybutadiene (HTPBD) chain in the presence of fumaryl chloride as extender. Blue light photocrosslinking system based on camphorquinone (photoinitiator) and dimethylaminoethyl methacrylate (accelerator) was applied to cure these two synthesized fumarate based macromers. Self-crosslinkability of unsaturated macromers and also crosslinking in presence of a reactive diluent were investigated in absence and presence of 1,4-butanediol dimethacrylate, respectively. Finally, photocured samples were characterized by XRD, SEM, equilibrium swelling study, TGA, DMTA, AFM and cell culture. The results showed that incorporation of POSS nanoparticle into the polymer matrix with a perfect distribution and dispersion can enhance thermal stability, mechanical and biocompatibility properties which can prove a good potential of this in-situ photocrosslinkable nanohybrid in medical applications.
