Aliphatic Polyurethane(脂肪族聚氨酯)研究综述
Aliphatic Polyurethane 脂肪族聚氨酯 - In this study, two innovative, highly reactive resins for use in the pultrusion process were analyzed, both resins based on aliphatic polyurethanes. [1] Polylactide and aliphatic polyurethane are biodegradable synthetic polymers which are broadly used as biomaterials in regenerative medicine for implants and scaffolds for tissue engineering. [2] A set of aromatic-oxyaliphatic polyurethanes (PUs) with different mass fractions of components also containing fluorinated fragments was synthesized and studied using various solid-state NMR techniques and dielectric spectroscopy. [3] As a result of a study of samples made of aliphatic polyurethane with steel reinforcement elements, it was found that there are traces of the penetration of high-speed particles into both metal and polymer layers. [4] Bionanocomposite scaffolds based on aliphatic polyurethane (PU) and bioactive glass nanoparticles were produced by using a one-step in situ polymerization method. [5] In this paper, the distributions of the 1H nuclear magnetic resonance (NMR) spin–lattice and spin–spin relaxation times are used to characterize the mobility of different sections of macromolecules of aliphatic polyurethanes and the cross-linking density of polymer chains. [6]在这项研究中，分析了两种用于拉挤成型工艺的创新型高反应性树脂，这两种树脂均基于脂肪族聚氨酯。 [1] 聚丙交酯和脂肪族聚氨酯是可生物降解的合成聚合物，广泛用作再生医学中的生物材料，用于组织工程的植入物和支架。 [2] 使用各种固态核磁共振技术和介电光谱法合成和研究了一组具有不同质量分数的组分的芳香族-氧脂肪族聚氨酯 (PU)，还含有氟化片段。 [3] 对由脂肪族聚氨酯制成的带有钢增强元件的样品进行研究的结果发现，存在高速颗粒渗透到金属和聚合物层中的痕迹。 [4] 采用一步原位聚合法制备了基于脂肪族聚氨酯（PU）和生物活性玻璃纳米粒子的生物纳米复合支架。 [5] 在本文中，1H 核磁共振 (NMR) 自旋晶格和自旋弛豫时间的分布用于表征脂肪族聚氨酯大分子不同部分的迁移率和聚合物链的交联密度。 [6]
