Hydrogels are synthetic or natural polymer networks crosslinked either chemically or physically to maintain 3D structures that are able to absorb and retain large amounts of water. [ 1 ] Porous biocompatible hydrogels combine porosity with biocompatibility and play an important role in various biomedical applications, such as scaffold materials in tissue engineering, cell transplantation, and …
A facile, green, low cost and efficient one-step technology to synthesize highly dispersible functional single-walled and multiwalled carbon nanotubes (f-SWNTs and f-MWNTs) up to supergrams is reported. Large-scale (up to hundreds of grams) synthesis of functional azides was developed at first, and various reactive groups (i.e., -OH, -NH2, -COOH, and -Br) were then introduced onto the convex…
