"Toughened hydrogels for biomedical application"

Abstract: Hydrogels are the three-dimensional polymer structure. The keen interest in the hydrogel is due to their properties like good water absorption, porous structure, biocompatibility and many more. For these reasons’ hydrogel has a huge scope in biomedical field. At present, the hydrogel used does not fulfil the demand up to its capabilities. The reason behind that is its poor mechanical properties. As the commonly used hydrogel (Poly (acrylic acid))/PAA has very weak mechanical properties. Therefore, there is great need to provide toughness to the conventional hydrogel so that its range of applications can be extended. The toughness is provided by the hyperbranched polymer (HB) to the conventional hydrogel.

In this thesis, various experiments were performed such as tensile testing, double peeling, water swelling test, FTIR and SEM. The properties of the hydrogel have improved by providing the enhancement to the conventional hydrogel in form of the hyperbranched polymer (HB). According to the experiments the PAA-HB hydrogel or the toughened hydrogel has the fracture toughness of 38.7J as compared to the 8.25J fracture toughness of the PAA i.e. conventional hydrogel.
