semi‐crystallineMultiphase latex particles containing semi‐crystalline domains can be used to reinforce the mechanical properties of coatings made using emulsion polymers, but their synthesis can be challenging. In this work, we show that simple latex blends involving a semi‐crystalline phase can ...
11.4.1 Material structure and properties Amorphous vs semi-crystalline Figure 11.8 shows the shear modulus and loss tangent of amorphous polymers over a range of temperatures. Amorphous polymer can maintain a high modulus of elasticity before it reaches the thermoelastic range (around glass transition ...
obtained. The amorphicity of poly-3R-caranmide and several co-polyamides is underlined by the preparation of transparent, sonlvent-cast films. A crystal structure of the semi-crystalline poly-3S-caranamide is also presented. As a conclusion, the great potential of these polyamides is shortly ...
By definition, a crystalline solid, also simply known as a crystal, is a solid material whose basic constituents such as atoms, ions, and molecules are arranged in a highly ordered and well-defined microscopic structure, known as a crystal lattice. These solids are formed in a process known ...
A shape memory polymeric material has a glass transition temperature, Tg, exceeding room temperature and exhibits rubber modulus and elasticity derived substantially from physical crosslinks is prepared by blending components including one crystalline polymer and two amorphous polymers. Methods of preparing ...
A pre-impregnated material includes a resin matrix reinforced with a fiber material. The matrix has a semi-crystalline layer based on semi-crystalline thermoplastic resin having a melting point Tf, on at least one side of which there is an amorphous surface layer based on amorphous thermoplastic ...
The elastic responses of crystalline and amorphous parts in semi-crystalline nylon 6 have been determined by computer simulation using the finite element method. Semi-crystalline nylon 6 has been modelled as a composite consisting of alternating layers of lamellar crystals and amorphous regions. Full ...
The main difference supposed is that the secondary phase has only local order compared with the final crystalline material that has long-range order. Recently, we have reported the application of the high-energy X-ray diffraction (HEXRD) method for the determination of the structure of the ...
摘要: Flow properties of polyamide-imide polymers are improved by the addition of semi-crystalline nylons or amorphous polyamides. These polymers are useful as engineering resins, laminates, and molded objects.收藏 引用 批量引用 报错 分享 全部来源 求助全文 掌桥科研 相似文献...
