| Abstract: | Starch materials were treated by 60Co-γ radiation and modification.The effect of irradiation dose,hot-pressing temperature,hot-pressing time and hot-pressing pressure on the mechanical property,water absorbing capacity and visible light transmission were studied and a good biodegradable material was prepared.The results showed that the optimal processing condition for the preparation material was irradiation dose 30 KGy,hot-pressing temperature 125 ℃,hot-pressing time 12 min,hot-pressing pressure 12 MPa.The elongation at break,tensile strength,visible light transmission and water absorbing capacity were 153.9%,4.28 MPa,48.6%and 61.26%respectively. |
