Fluoralkylpolysiloxane modified Polyurethane (FSPU) films with high water contact angle (CA) were prepared. fluoralkylpolysiloxane was obtained using perfluoro octyl sulfuryl fluoride and terminal amino-silicone oil as reactants. Then, the isocyanate end capped PU prepolymer was synthesized by reacting isocyanate with a soft segment mixed by active amino-end-capping fluoralkylpolysiloxane and polyether glycol. The fluoralkylpolysiloxane modified PU films were obtained after the PU prepolymer was cured by 3,3 '- dichloro -4,4' – amino - diphenyl methane (MOCA). The results showed that the modified polyurethane with 10% (mass fraction) PFATPS had a good compatibility, low surface energy, surface water contact angle and surface oil contact angle was improved by 49° and 37° respectively, and heat resistance, water resistance was apparently improved.

To solve the problem of pigment printing’s hard handle and poor fastness, we have synthesized an amino silicone oil / acrylic emulsion blending adhesive to improve the printing handle and fastness in the paper. We studied the synthetic monomers and influencing factors to explore the best synthesis process of the acrylic emulsion polymerization. The synthetic acrylic emulsion and amino silicone were blended to explore the best printing process. We find that the printed fabrics have a good handle and significantly better rubbing fastness.

The mechanical and dynamic mechanical properties, interface adhesion and microstructures of the amino silicone oil emulsion (ASO) modified short ramie fiber reinforced polypropylene composites (RFPCs) with different fiber fractions were investigated. The RFPCs were made through a combined process of extrusion and injection molding. Mechanical property tests of the RFPCs revealed enhancements in tensile and flexural strengths with increase of the fiber fraction due to the high stiffness of the fiber filler and a better interfacial bonding from ASO treatment. The dynamic mechanical analysis (DMA) results indicated that fiber incorporation plays an important role in DMA parameters (storage modulus, loss modulus, and damping ratio) at Tg by forming an improved interfacial adhesion and providing more effective stress transfer rate and energy dissipation between matrix and fiber. The phase behavior analysis suggests all the RFPCs are a kind of heterogeneity system based on the Cole-Cole plot analysis.

Using amino silicone oil and fluorinated acrylate as raw material, fluoroalkyl group modified amino-silicone oil was synthesized by primary amino group and C=C double bond of fluoroacrylate via Michael addition reaction. The fluoroalkyl modified silicone oil with different content of fluorine were obtained by changing the ratio of feeding. Then the fluoroalkyl modified silicone oil was applied on deep dyeing finishing on colored silk fabric. The relationship between the fluorine content of modified amino-silicone oil and the refractive index was discussed, as well as the effect of the increasing of depth on silk fabric. The result showed that 15g/L of finishing agent can afford 35% upgrade rate of dyeing depth on colored silk fabric when the fluorine content was 37.32%. SEM, FT-IR and XPS showed that treatment of the fluoroalkyl modified aminosilicone oil can form the polymeric layer on the silk fiber surface with low refractive index, and the lower the refractive index of the fluoroalkyl modified amino-silicone oil is, the better the upgrade of the deep dyeing finishing will be.
