レーザー走査照射による高強度ゲルの3次元光造形 3-Dimensional Freeform Fabrication of High-Strength Gels by Laser Scanning Irradiation
Access this Article
Double network (DN) gel is one of high-strength strongest gels in the world. Its maximum stress in compression is over 30MPa, and its surface frictional coefficient is 0.0001 at suitable conditions. Thus the DN gels realize both anomalously high strength and extremely low friction at the same time. The DN gels will be possibly used as medical materials. Here a system, which can make 3-dimensional optical forming of the DN gels by using ultraviolet laser, was proposed in order to make an artificial blood vessel experimentally. A suitable forming scheme is found, and the mechanical strength of the vessel is evaluated. The artificial vessels formed by DN gels are promising, since this material can penetrate water, oxygen, etc. Thus, the vessel can work more naturally in human bodies.
