1. 含氟硅功能高分子材料、结构可控杂化材料及其自组装高性能涂膜材料

Fluorin/silicon-containing functional copolymers, structure-controllable hybrids and their self-assembly behavior for high performance coatings

1)  Fluorinated acrylic copolymers (FACs) has become a focused point in high-performance coating materials

     due to their excellent surface properties of fluorine-containing polymer and favorable adhesive strength to the

     substrate of acrylate polymer. The low free energy surface of FACs could be obtained by controlling the surface

     chemical composition and by the self-assembly behavior. The aim of research is to synthesize FACs with core-

     shell structure by emulsion and block structure by ATRP or RATF with well-defined chemical structure and tailored                               properties, and to investigate their possible self-assembly behavior in film-formation.

2) The researched copolymer/SiO₂ nanohybrids are made of fluorinated copolymers (FPs) or silicon-contained

      copolymers (SCPs) and SiO₂. FPs/SiO₂ or SCPs/SiO₂ film in micro/nano hierarchical morphology (high roughness)

      and self-migration into top surface of fluorinated groups or silicon-contained groups (low surface free energy) have

      make it possible to obtain excellent water and oil repellence and the strong adhesion to the substrate. The aim is to                            investigate the hydrophobic and adhesive properties of FPs/SiO₂ or SCPs/SiO₂ nanohybrids synthesized by ATRP/

      sol-gel and SI-ATRPATRP techniques, to regulate the distribution of aggregated micelles by self-assemble behavior

      as the micro/nano hierarchical morphology of film surface.

2. 复杂体系及天然高分子化合物的识别与检测分析

The characterization of natural polymeric compounds and complex system

       Normally, the polychromy is made of pigments and natural polymer as binding medium. The binding medium

plays a key role in the polychromy for fixing the pigments onto the substrate supporter to form the painting layers.

However, the binding medium is easy to be deteriorated with time to cause the damage or extinction of the precious                         polychromic artworks. But the preciousness and non-reproducibility of ancient polychromy, and the lack of targeted

analytical methods, the limitation of pertinence identification system and standard references, have made the identification

of binding medium and pigments very challengeable. Therefore, it is necessary to improve the effective and feasible

analytical methods and techniques. The study aims to research the nondestructive and in-situ detecting techniques, the

 suitable and accurately spectrum database and microanalysis recognition system. The research is focused on：1).

 Establishing the targeted analytical methods and the spectrum database by ATR-FTIR, RS and XRF nondestructive techniques for

 recognizing the pigment and binding medium; 2). Developing the microanalysis methods and recognition system for identification of binding                  medium by GC/MS and Py-GC/MS.
