本材料主要由含有机官能团的剥离石墨烯纳米薄片组成。含氧量低于5%；大部分基团是羟基(OH)，可进一步化学改性形成新官能团。通过功能化方法可使官能团连接薄片边缘的大部分基团，以保持石墨烯本身的性质（如导电性）。

应用

本品可分散和/或掺入到极性溶剂（如水、THF和DMF）和极性聚合物基质（如PLA、PA和PET）中。适合用于原位聚合、树脂直接混合和模压成型、溶剂溶解、掺入后挤出加工。应用：
  • 纳米复合材料[1,2]
  • 耐腐蚀涂料[3,4]
  • 阻隔性膜[5,6]
  • 分离膜[7,8]
  • 导电油墨[9,10]
  • 能源储备[11,12]

Alginate-based materials hold great promise in bioengineering applications such as skin wound healing and scaffolds for tissue engineering. Nevertheless, cell adhesion of mammalian cells on these hydrophilic materials is very poor. In cases such as polycaprolactone, poly(hydroxy-3-butyrate-co-3-valerate) and gelatin, the

Alginate is considered an exceptional biomaterial due to its hydrophilicity, biocompatibility, biodegradability, nontoxicity and low-cost in comparison with other biopolymers. We have recently demonstrated that the incorporation of 1% graphene oxide (GO) into alginate films crosslinked with Ca2+ cations provides
