2.8 Nomenclature of samples
To describe the samples, the nomenclature rule was followed:
1) The precursor of hydrogel contain carrageenan named KC;
2) The precursor of hydrogel contain carrageenan and sodium alginate
named KC-SA;
3) The precursor of hydrogel contain carrageenan,sodium alginate and
carbon nanotube named KC-SA-C; KC-SA-C-0.3 indicate percentage
composition of carbon nanotube;
4)KC-SA-C-15kpa indicated sample KC-SA-C-0.3 was printed at 15kpa of
printing pressure.
