Good biocompatibility, biodegradability  and non-toxicity are expected with hydrogel composites based on chitosan, acrylic acid, and cellulose nanofibrils.

I would recommend using polyester urethane you can easily tailor the properties and cross linkers can be added as well. Some PEG based hydrogels have also shown promising results. 

Another option is using natural polymers like collagen chitosan or Hyaluronic acid and cross linking with proanthocyanadins or riboflavin both have shown good compatibility 

Hope this helps
