Abstract

Using modified amino ethers of boric acid, porous polyurethanes are synthesized, the porous morphology of which is due to the peculiarities of the hyperbranched macromolecular architecture of amino ethers of boric acid. A change in the structure of amino ethers of boric acid by the introduction of terminal bulky substituents with hydroxyl groups contributes to a change in the size and pore size distribution of polyurethanes based on amino ethers of boric acid. It is shown that one of the reasons for the heat-sensitive vapor permeability of porous polyurethanes is the hydrophilic nature of the pore surface. Film samples of porous polyurethanes have proven to be an effective substrate for the targeted cultivation of connective tissue at the cellular level.

基于硼酸改性氨基醚的聚氨酯

摘要

使用硼酸的改性氨基醚合成了多孔聚氨酯，其多孔形态是由于硼酸的氨基醚的超支化大分子结构的特殊性。通过引入带有羟基的末端庞大的取代基来改变硼酸氨基醚的结构，有助于改变基于硼酸氨基醚的聚氨酯的尺寸和孔径分布。结果表明，多孔聚氨酯的热敏蒸气渗透性的原因之一是孔表面的亲水性。多孔聚氨酯薄膜样品已被证明是在细胞水平上靶向培养结缔组织的有效基质。
