Abstract
The research goal of this experiment is chemically to cross-link poly(vinyl alcohol) (PVA) and starch to form a 3D scaffold that is effective water absorbent, has a stable structure, and supports cell growth. PVA and starch can be chemically cross-linked to form a PVA-g-starch 3D scaffold polymer, as observed by Fourier transform infrared spectroscopy (FTIR), with an absorbency of up to 800%. Tensile testing reveals that, as the amount of starch increases, the strength of the 3D scaffold strength reaches 4Â ÃÂ 10â2Â MPa. Scanning electron microscope (SEM) observations of the material reveal that the 3D scaffold is highly porous formed using a homogenizer at 500Â rpm. In an enzymatic degradation, the 3D scaffold was degraded by various enzymes at a rate of up to approximately 30-60% in 28 days. In vitro tests revealed that cells proliferate and grow in the 3D scaffold material. Energy dispersive spectrometer (EDS) analysis further verified that the bio-compatibility of this scaffold.
