Examples
- It was found that introduction of hydrophobic monomer into polymer chain improved the response linearity and sensitivity , and the impedance of sensors decreased with longer quaternization time and shorter distance between electrode tracks
发现：疏水性单元的引入，提高了湿敏元件的响应线性度和灵敏度；季胺化时间的延长，使聚合物季胺化程度提高，湿敏元件阻抗减小；电极叉指间距增大，阻抗增大。 - Pdmaema can be cross - linked by quaternization to develop a positively charged dense network structure . according this mechanism , pdmaema / psf positively charged nanofiltration membrane was developed by interfacial polymerization using psf plate macrofiltration membrane as support layer , pre - polymer of pdmaema water solution as coating solution , p - xylylene dichloride / heptane as cross - linking agent
根据这一机理，以psf平板微孔膜为基膜， pdmaema预聚物水溶液为涂层液，以对二氯苄正庚烷溶液为交联剂，采用界面聚合法制备了pdmaema psf荷正电复合纳滤膜。 - Simultaneously cross - linked and quaternized 4 - vp - co - nbuma was also investigated as humidity sensing materials and showed good linearity , high sensitivity , good high stability at high humidity and high temperature , and durability to organic solvent , etc . sensors based on 4vp - co - buma ( vp / buma = l / l ) with crosslinking and quaternization reaction of 17 hours exhibited a change of three orders of magnitude ( 104 ~ 107 ) in impedance over the range of 95 % rh ~ 30 % rh , showing high sensitivity , and little hysteresis was observed
元件具有响应线性度好，灵敏度高，湿滞小、高温高湿稳定性好、耐无水乙醇有机溶剂性能好等优点。其中，交联季胺化17小时配料比为1 1共聚物湿敏元件，在33 rh 95 rh湿度范围内，阻抗变化达3个数量级( 10 ~ 7 - 10 ~ 4 ) ，响应灵敏度高，几乎无湿滞。
