For the two-echelon supply chain with stable market demand, by taking the supplier’s capital constraint into consideration, we establish a conditional and partial trade credit model, which actually is a Stackelberg model with the supplier being a leader in the game. By analyzing two parties’ optimal decisions in the game, we provide the supplier with a threshold for setting the model. The model can not only stimulate the retailer to make a larger order at each replenishment cycle, but also incite the retailer to make a partial payment when he is in a good financial condition. Hence, the supplier’s financial pressure is marginally relieved in this model. On the other hand, the retailer’s benefit in the traditional trade credit model does not decrease. Thus, the new model makes the supply chain more stable and a win–win outcome can be realized. We illustrate the validity of the model via a set of numerical experiments. The sensitivity and the Pareto optimality of the model are also discussed in this paper. [ABSTRACT FROM AUTHOR]

The photoinduced deformation properties in azobenzene-containing polymers can convert light energy into mechanical energy. At present, there are few types of photoinduced deformable polymers based on azobenzene-containing high performance polymers, and new types of high performance azobenzene-containing polymers need to be developed. Here, a series of azobenzene-containing poly (arylene ether)s with various azobenzene contents were synthesized. These azobenzene-containing polymers showed high glass transition temperatures and high thermal stabilities. The photoisomerization behavior and the photoinduced deformation behavior of these azobenzene-containing polymers were studied upon exposure to a 442 nm linearly polarized laser and a 532 nm linearly polarized laser, respectively. Both of the photodeformation rate and the maximum photoinduced bending angles of the polymers increased with increasing azobenzene content. To our knowledge, it is the first report on photoinduced deformation properties of azobenzene-containing poly (arylene ether)s. In addition, the photoinduced bending rate and maximum photoinduced bending angle of the cantilever under 442 nm laser excitation were higher and larger than that under 532 nm laser excitation, respectively. • A series of azobenzene-containing poly(arylene ether)s are synthesized. • All polymers show well thermal stabilities. • The photodeformation rate of the polymers increase with increasing azobenzene content.
