通过向弱交联网络或非交联线性链的双网络凝胶（DN凝胶）中添加第三种组分（以分别产生三网络凝胶（TN凝胶）和DN-L凝胶，见图），可生产高强度、低摩擦系数凝胶。所有凝胶都是高度透明的。DN-L凝胶在亚MPa量级的极高压力下显示出高达9 MPa的断裂强度和低至10（-5）的摩擦系数。
High-strength, low-frictional-coefficient gels are produced by adding a third component to a double-network gel (DN gel), of either a weakly crosslinked network or non-crosslinked linear chains (to produce, respectively, a triple-network gel (TN gel) and a DN-L gel, see Figure). All the gels are highly transparent. The DN-L gel shows a fracture strength as high as 9 MPa and its frictional coefficient is as low as 10(-5) under an extremely high pressure of the order of sub-MPa.
