Abstract:
Chitosan (CS)-based porous hydrogels are very attractive nowadays due to their interesting properties, such as biocompatibility, bioactivity, non-toxicity, and biodegradability. Thus, they have been used as integral parts in various applications (e.g. biomedicine, agriculture and industry). However, chitosan itself gives porous hydrogels with low mechanical properties. In this present study, the mechanical properties of chitosan porous hydrogels can be enhanced by the introduction of oppositely charged polymers as physical crosslinkers or by the addition of reinforcing fillers, which are the negatively- charged alginate (Alg) and two reinforcing fillers poly(hydroxyethyl methacrylate) poly-ethyleneimine (PHEMA PEI) core-shell particles and or short pineapple leaf fibers (PALFs), respectively. The results show that the incorporation of both PHEMA PEI particles and PALFs can improve the compressive modulus of CS Alg porous hydrogels from 0.0260MPa up to 0.0706MPa and increase percentwater uptake in deionized water from 1165 percent to 1483 percent with the same percentporosity about of 80 percent. In addition, they also exhibited high physical stability in acid and basic solutions. It is very promising that the addition of PHEMA PEI particles and PALFs could bring the benefits to chitosan-based porous hydrogels, due to the extra amine functional groups from the PHEMA PEI particles and high mechanical strength from PALFs, without chemical crosslinker
