Organic/Inorganic Hybrid materials from polypeptide-based block copolymers
Reactive and Functional Polymers, 2009Co-Authors: Sophie Monge, Olivia Giani, Xuewei Zhang, Jean Jacques RobinAbstract:Novel organic/Inorganic Hybrid material was synthesized from poly(acrylazapropyl-trimethoxysilane)-b-poly( Ne-trifluoroacetyl-L-lysine) (P(AAPTMS)-b-P(TLL)) block copolymer using the sol–gel process. The treatment with ammonia solution permitted the hydrolysis of both trifluoro acetyl and trimethoxysilyl groups of the hydride copolymer followed by the condensation of the silanol groups, leading to crosslinked copolymers. The resulting cross-linked Hybrid material was characterized using FT-IR, 29Si NMR, DSC, TGA, and environmental scanning electron microscopy. These techniques evidenced that a siloxane network was obtained. Amphiphilic polypeptide/Inorganic Hybrid copolymers were achieved and selforganized as particles in water.

Synthesis of polypeptide/Inorganic Hybrid block copolymers
European Polymer Journal, 2008Co-Authors: Xuwei Zhang, Olivia Giani, Sophie Monge, Jean Jacques RobinAbstract:Polypeptide/Inorganic Hybrid copolymers were obtained by a four-step synthetic approach combining (i) atom transfer polymerization of tert-butyl acrylate, (ii) chemical modification of the bromo end groups of ATRP-polymers into primary amino group using Gabriel reaction, (iii) ring opening polymerization of Nε-trifluoroacetyl-l-lysine or γ-benzyl-l-glutamate N-carboxyanhydrides followed by (iv) the transamidification reaction using a large excess of (3-aminopropyl)trimethoxysilane to substitute the tert-butyl groups of the poly(tert-butyl acrylate) block. Products were characterized using 1H NMR, FT-IR, DSC and MALDI-TOF MS. These techniques proved that polymerization of tert-butyl acrylate was controlled whatever the molecular weight targeted and that bromide was quantitatively converted to amino end group by a original method leading to the synthesis of copolymers in the presence of N-carboxyanhydrides as monomers. Amphiphilic polypeptide/Inorganic Hybrid copolymers were then achieved.

Preparation of UV curable organic/Inorganic Hybrid coatings-a review
Progress in Organic Coatings, 2020Co-Authors: Liu Fengguo, Aimin Liu, Wenju Tao, Youjian YangAbstract:Abstract The ultraviolet (UV) curable organic/Inorganic Hybrid coating is a kind of environment friendly paint products with rapid development in recent decade. It combines UV curing and nanofabrication technique. Due to its distinct advantages of zero volatile organic compounds emission, high curing rate at room temperature, and excellent performance, UV curable organic/Inorganic Hybrid coating has been considered as a green product with extensive application prospect. In this review, we focus on the preparation methods of UV curable organic/Inorganic Hybrid coatings including blending method, sol gel process, intercalation and in-situ reaction. All the preparation methods have the same core concept of incorporation between the organic and Inorganic composition in molecular level in order to take full advantages of both organic and Inorganic composition. The properties of Hybrid coatings can be enhanced by the Inorganic incorporation into the organic matrix, such as abrasive resistance, heat resistance, corrosion resistance, chemical stability and etc. The research progress on different Inorganic particles applied in UV curable organic/Inorganic Hybrid coatings is also summarized.

Highly Efficient Red-Light Emission in An Organic–Inorganic Hybrid Ferroelectric: (Pyrrolidinium)MnCl3
Journal of the American Chemical Society, 2015Co-Authors: Yi Zhang, Wei-qiang Liao, Zhong-ning Chen, Ren-gen XiongAbstract:Luminescence of ferroelectric materials is one important property for technological applications, such as low-energy electron excitation. However, the vast majority of doped Inorganic ferroelectric materials have low luminescent efficiency. The past decade has envisaged much progress in the design of both ferroelectric and luminescent organic–Inorganic Hybrid complexes for optoelectronic applications. The combination of ferroelectricity and luminescence within organic–Inorganic Hybrids would lead to a new type of luminescent ferroelectric multifunctional materials. We herein report a Hybrid molecular ferroelectric, (pyrrolidinium)MnCl3, which exhibits excellent ferroelectricity with a saturation polarization of 5.5 μC/cm2 as well as intense red luminescence with high quantum yield of 56% under a UV excitation. This finding may extend the application of organic–Inorganic Hybrid compounds to the field of ferroelectric luminescence and/or multifunctional devices.
