Biological ion channels, as fundamental units participating in various daily behaviors with incredible mass transportation and signal transmission, triggered booming researches on manufacturing their artificial prototypes. Biomimetic ion channel with the nanometer scale for smart responding functions has been successfully realized in sorts of materials by employing state-of-art nanotechnology. Ion track-etching technology, as crucial branches of fabricating solid-state nanochannels, exhibits outstanding advantages, such as easy fabrication, low cost, and high customization. To endow the nanochannel with smart responsibility, various modification methods are developed, including chemical grafting, non-covalent adsorption, and electrochemical deposition, enriching the reservoir of accessible stimuli-responses combinations, whereas were limited by their relatively lengthy and complex procedure. Here, based on the electric field induced self-assembly of polyelectrolytes, a universal customizable modifying strategy has been proposed, which exhibits superiorities in their functionalization with convenience and compatibility. By using this protocol, the channels’ ionic transport behaviors could be easily tuned, and even the specific ionic or molecular responding could be realized with superior performance. This strategy surely accelerates the nanochannels functionalization into fast preparing, high efficiency, and large-scale application scenarios.

基于K_(2)O-B_(2)O_(3)-SiO_(2)三元体系玻璃,在固定玻璃组成参数R值的基础上,设计了不同玻璃组成参数K值含Ag碱硼硅酸盐玻璃。采用熔融法制备了基础玻璃,在析晶温度范围内经过一步法热处理,所有样品内部都析出了球形的AgCl晶粒。研究表明,玻璃组成参数K值对含Ag碱硼硅酸盐玻璃体内AgCl晶粒的析出产生了明显影响。对于设计制备的弱分相体系玻璃,玻璃组成参数K值的改变可以影响玻璃网络的聚合度,但玻璃的分相并不是影响玻璃析晶的主要因素。通过玻璃结构分析,玻璃组成参数K值的改变能够对ZrO_(2)在玻璃网络中的存在状态产生影响,进而降低ZrO_(2)在玻璃网络中的溶解度,增加了基础玻璃中的成核位点,从而对含Ag碱硼硅酸盐玻璃的AgCl析晶行为产生重要影响。
