As the polymer transforms to the collapsed state, multilayer PNIPAM forms on the same substrate.
而当聚合物转变到塌缩态时,同样的底层上会形成多层膜。
The time constant for PNIPAM in the collapsed state is nearly temperature- and concentration-independent.
塌缩状态下PNIPAM的吸附时间常数基本上不依赖于温度和浓度。
The graft copolymer HPG-g-PNIPAM shows the Lower Critical Solution Temperature (LCST), and the relationship between the LCST and structure was studied.
测定了其聚合物的低临界共溶温度(LCST),并初步研究了聚合物的结构与LCST之间的关系。
By analysis, it is considered that the reason causing this difference is the conformational adjust mechanism which leads the HS-PNIPAM to form polymer brush finally.
分析认为,导致这种差异的主要原因在于PNIPAM分子具有构象的调整机制,整个吸附生长过程就是其构象不断调整直至形成分子刷的过程。
Fluorescence anisotropy via ACE label studies revealed that addition of salt decreases the segmental mobility of the PNIPAM chain, and thereby decreases the LCST of the polymer.
荧光各向异性研究表明盐的加入降低了PNIPAM链的柔性,从而使其相变温度降低。
Along with the further research and development work, in the near future, heat-sensitive PNIPAM will be in the field of chemical industry, medicine, biology, materials play an irreplaceable role.
随着研究和开发工作的进一步深入,在不久的将来,热敏性PNIPAM将在化工、医学、生物、材料领域中起着不可替代的作用。
Interfacial polymerization was introduced to prepare polyamide porous microcapsules, and plasma-graft pore-filling polymerization was used to graft PNIPAM into the pore of the microcapsule membranes.
实验中采用界面聚合法制备聚酰胺多孔微囊,然后利用等离子体接枝填孔聚合法将PNIPAM接枝在微囊壁的膜孔中。
