Polymer chain

原声例句
TED演讲(视频版) 2019年2月合集

And we can even create more elaborate structures if we use unsymmetrical molecules, where one polymer chain is significantly shorter than the other.

如果我们使用不对称分子,我们甚至可以创造出更精细的结构,那种情况下其中一个聚合物链明显短于另一个。

TED演讲(视频版) 2019年2月合集

And the size of this cylinder and the distance between the cylinders, the periodicity, is again determined by how long we make the polymer chains and the level of built-in frustration.

这个圆柱体的大小和圆柱体之间的距离,周期性,也是由我们制造聚合物链的时间长短和内部障碍程度决定的。

TED演讲(视频版) 2019年2月合集

And the width of the fingerprint lines and the distance between them is determined by the lengths of our polymer chains but also the level of built-in frustration in the system.

指纹线的宽度和它们之间的距离是由我们的聚合物链的长度决定的,同时也由系统内嵌的挫折程度决定。

聚合物 Polymer

(重定向自Polymer chain)
聚合物
El poliestireno es un polímero formado a partir de la unidad repetitiva conocida como estireno.
Tacticidad de poliestireno, atáctico, sindiotáctico, isotáctico.
La estructura puede ser lineal o también ramificada (aparte de poder presentar entrecruzamientos). También pueden adoptar otras estructuras, por ejemplo radiales.

有机聚合物英语:Polymer)是指具有非常大的分子量的化合物,分子间由结构单位(structural unit)、或单体由共价键连接在一起 。 这个聚合物(polymer)是出自于希腊字:polys代表的是,而meros 代表的是小单位(part),所以很多小单位链接在一起的这种特别的分子,我们称之为聚合物。可以参考塑胶、DNA和高分子。

Appearance of real linear polymer chains as recorded using an atomic force microscope on a surface, under liquid medium. Chain contour length for this polymer is ~204 nm; thickness is ~0.4 nm.[1]
The repeating unit of the polymer polypropylene
Microstructure of part of a DNA double helix biopolymer
IUPAC definition

Substance composed of macromolecules.

Note: Applicable to substance macromolecular in nature like cross-linked
systems that can be considered as one macromolecule.

A polymer (/ˈpɒlmər/; Greek poly-, "many" + -mer, "parts") is a large molecule, or macromolecule, composed of many repeated subunits. Because of their broad range of properties, both synthetic and natural polymers play an essential and ubiquitous role in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, viscoelasticity, and a tendency to form glasses and semicrystalline structures rather than crystals.
