Hybrid calcium carbonate (CaCO3)/poly(styrene sulfonate) (PSS) particle, as a template, was synthesized using colloidal crystallization with the presence of nitrate tetrahydrate (Ca(NO3)2•4H2O), sodium carbonate (Na2CO3) and PSS. Microcapsule was prepared by template-assisted layer-by-layer (LbL) technology in solutions of two oppositely charged polyelectrolytes, poly(styrenesulfonate) (PSS) and poly(allylamine hydrochloride) (PAH) alternately, followed by dissolving the template with disodium ethylenediaminetetraacetate (EDTA). The release behavior of rhodamine B (RhB) from the microcapsules was examined and the rates of release at different pH were studied.

Abstract In this study, intumescent flame retardant coating of polyethylenimine/phytic acid (PEI/PA) with gradient structure was constructed on cotton fabric through facile layer-by-layer (LBL) assembly method. The LOI value of coated cotton fabric reached over 40% indicating excellent flame retardancy. Reasonable controlling the LBL assembly process of PEI/PA coating brought less influence to the physical properties of cotton fabrics. And the coated cotton fabric revealed good flame retardant washing durability. Thermogravimetric analysis results of coated cotton fabrics showed that PEI/PA flame retardant coating changed the thermal decomposition process and promoted char formation revealing the obviously condensed phase flame retardant action. SEM images of char residues revealed that PEI/PA flame retardant coating promoted to form the intumescent flame retardant (IFR) char layer showing obvious IFR action. This research provides novel strategy for the development of high-efficiency flame retardant cotton fabric with good durability and physical properties using simple LBL assembly method.

Poly Styrene Sulfonate

Multilayer thin films were prepared based on hydrogen bonding between poly(N-isopropylacrylamide) (PNiPAAm), and poly(styrene sulfonate-co-maleic acid) (PSSMA). Since PSSMA is capable of associating with other polymers through both hydrogen bonding and electrostatic interactions, multilayer assemblies incorporating PSSMA, PNiPAAm, and intercalated poly(allylamine hydrochloride) (PAH) layers were also prepared. Intercalated PAH layers were included to improve the pH stability of the film by introducing electrostatic linkages into the assembly. Film construction was studied as a function of pH of the deposition solution and the number of inserted PAH layers. Film morphology varied significantly with incorporation of PAH into the film. It was also demonstrated that by intercalating several PAH layers within the PNiPAAm/PSSMA assembly, the pH stability of the films at pH 5.8 could be substantially improved.
