    • An organic polyurethane shape memory material and a preparation method thereof are disclosed. The organic polyurethane shape memory material includes a C10 chain or C18 chain and it consists of hard segment and soft segment. The preparation method thereof includes the steps of:The single-chain type dendrimer reacts with diethylenetriamine to produce multiple chains type dendrimer. And then at least one type dendrimer reacts with N-(3-aminopropyl)diethanolamine to produce at least one type dendritic diols. Next polymer HO(C6H10O2)xC2H4OC2H4(C6H10O2)yOH, x+y=25˜26 reacts with methylenedi-p-phenyl diisocyanate and then at least one type dendritic diols is added to react so as to get organic polyurethane shape memory material. The material of the present invention overcomes shortcoming of metal alloy and ceramic such as poor processability, difficulty in modification and high cost. Moreover, it also increase mechanical properties of polymer.

    • A nonlinear optical interpenetrating polymer network which can exhibit nonlinear optical properties includes a first polymer, and a second polymer interpenetrating the first polymer. At least one of the polymers includes a nonlinear optical component. A method of forming a nonlinear optical interpenetrating polymer network which can exhibit nonlinear optical properties includes combining a first prepolymer, which can react to form a first polymer, with at least one monomer which can react to form a second polymer. At least one of either the first prepolymer or the monomer include a nonlinear optical component. The nonlinear optical component is poled and the first prepolymer and the monomer, or monomers, of the second prepolymer are reacted while the nonlinear optical component is being poled. The reaction of the first prepolymer forms a first polymer network and reaction of the monomer(s) form a second polymer network which interpenetrates the first polymer network to form an interpenetrating polymer network. The interpenetrating polymer network fixes the nonlinear optical component in the poled position, thereby forming an interpenetrating polymer network which exhibits nonlinear optical properties.
