The cyclopentasilane may be polymerized in the presence of a palladium catalyst supported on a polymer. The palladium catalyst supported on a polymer may be a catalyst in which palladium as a catalyst component is immobilized on a functional polystyrene. The palladium may be a palladium compound or a palladium complex.
Abstract: The present invention relates to antifouling coatings capable of being switched by using heat or ultraviolet light. Prior to switching, the coating includes an onium cation component having antimicrobial and antibacterial properties. Upon switching, the coating is converted to a conjugated polymer state, and the cationic component is released with any adsorbed biofilm layer. Thus, the coatings herein have switchable and releasable properties. Methods of making and using such coatings are also described.

Abstract: Disclosed is a self-healing polysilsesquioxane and a hybrid film using the same. Once crosslinked, the polysilsesquioxane copolymer can self-heal within several minutes at 100-120° C. The self-healing polysilsesquioxane copolymer can be prepared into a hybrid material in the form of a film. Because the hybrid film has an excellent ability of self-healing the damage caused by external impact, it is applicable to wide applications such as gas separation membranes, etc., without limitation.

Abstract: Disclosed is a highly fluorinated silicone resin and a method for making the same. The silicone resin includes M, T, optionally D and optionally Q type monomers and is crosslinkable. The resin has a fluorine content of at least 55 weight percent and a very low refractive index of less than 1.4. The resin is formed in a one step process and requires use of very specific solvents. Preferably the resin includes a first T type monomer having a fluoroalkane group to provide the fluorine to the resin. Preferably the resin includes a second T type monomer having a (meth)acryloyl function to enable cross-linking. The resin forms an effective liquid optically clear adhesive. The resin can be further combined with highly fluorinated (meth)acrylate monomers or perfluoro polyethers to provide even lower refractive indexes and improved adhesive properties.
