Abstract: A saltwater corrosion resistant composite coating is described. The coating includes at least one conductive polymer, chitosan, reduced graphene oxide (rGO), and a cured epoxy. The rGO and chitosan are dispersed in particles of the conductive polymer to form a 3D network. At least a portion of the chitosan is covalently bound to the rGO. At least a portion of the conductive polymer is covalently bound to the chitosan, and the 3D network is dispersed in the cured epoxy.

Abstract: A method of making a structural lightweight and thermal insulating concrete is described. The concrete has a coarse aggregate partly replaced by recycled plastic pieces. This enables the concrete to maintain a high compressive strength, low thermal conductivity, and low weight, while providing a use for waste plastic. The waste plastic pieces may comprise polyethylene in the form of flakes, fibers, or granules. Due to its low unit weight, adequate compressive strength and high thermal resistance the developed concrete can be used as a structural lightweight and thermal insulating concrete. The use of this concrete leads to economic and environmental benefits.

Abstract: Poly(acrylic acid) polymer blends comprising poly(acrylic acid) and glycerol, the glycerol content being 25-75% by weight based on the weight of the poly(acrylic acid). The polymer blends are miscible; they retain the ability to absorb large volumes of liquids and also exhibit rubber viscoelasticity. The incorporation of glycerol reduces the glass transition temperature of the blends dramatically. The process of preparing the poly(acrylic acid) polymer blends by solution casting is described. Methods of measuring the glass transition temperature and the tensile strength of the polymer blends are also provided.

Abstract translation: 包含聚（丙烯酸）和甘油的聚（丙烯酸）聚合物共混物，基于聚（丙烯酸）的重量，甘油含量为25-75重量％。 聚合物共混物是可混溶的; 它们保持吸收大量液体的能力，并且还具有橡胶粘弹性。 甘油的掺入显着降低了混合物的玻璃化转变温度。 描述了通过溶液流延制备聚（丙烯酸）聚合物共混物的方法。 还提供了测量聚合物共混物的玻璃化转变温度和拉伸强度的方法。
