Hard–soft–hard triblock copolymers based on poly(ethylene oxide) (PEO), poly(2-naphthyl glycidyl ether)-block-poly[2-(2-(2-methoxyethoxy)ethoxy)ethyl glycidyl ether]-block-poly(2-naphthyl glycidyl ether)s (PNG-PTG-PNGs), were synthesized by sequential ring-opening polymerization of 2-(2-(2-methoxyethoxy)ethoxy)ethyl glycidyl ether and 2-naphthyl glycidyl ether using a bidirectional initiator catalyzed by a phosphazene base. Four PNG-PTG-PNGs had different block compositions (f_wt,PNG = 9.2–28.6 wt %), controlled molecular weights (M_n = 23.9–30.9 kDa), and narrow dispersities (Đ = 1.11–1.14). Most of the PNG-PTG-PNG electrolytes had much higher Li⁺ conductivities than that of a PEO electrolyte (6.54 × 10^–7 S cm^–1) at room temperature. Eespecially, the Li⁺ conductivity of PNG₁₈-PTG₁₀₇-PNG₁₈ electrolyte (9.5 × 10^–5 S cm^–1 for f_wt,PNG = 28.6 wt %) was comparable to one of a PTG electrolyte (1.11 × 10^–4 S cm^–1). The Li⁺ conductivities of PNG-PTG-PNG electrolytes were closely correlated to efficient Li⁺ transport channels formed by the microphase separation into soft PTG and hard PNG domains.

硬-软-硬三嵌段共聚物的合成，聚（2-萘基缩水甘油基醚） -嵌段-聚[2-（2-（2-甲氧基乙氧基）乙氧基）乙基缩水甘油醚] -嵌段-聚（2-萘基缩水甘油基醚），用于固体电解质

基于聚环氧乙烷（PEO），聚（2-萘基缩水甘油醚）-嵌段的硬-软-硬三嵌段共聚物-聚[2-（2-（2-（2-甲氧基乙氧基）乙氧基）乙基）缩水甘油醚]-嵌段-聚（2-萘基缩水甘油醚）（PNG-PTG-PNGs），是通过双向使用2-（2-（2-甲氧基乙氧基）乙氧基）乙基缩水甘油醚和2-萘基缩水甘油醚的连续开环聚合反应合成的由磷腈碱催化的引发剂。四PNG-PTG-的PNG有不同的块组合物（˚F_重量，PNG = 9.2-28.6重量％），控制的分子量（中号_Ñ = 23.9-30.9 kDa的），和窄分散度（Đ = 1.11-1.14）。大多数PNG-PTG-PNG电解质具有更高的Li ⁺在室温下，电导率比PEO电解质（6.54×10 ^–7 S cm ^–1）高。尤其是，PNG ₁₈ -PTG ₁₀₇ -PNG ₁₈电解质的Li ⁺电导率（f _wt为9.5×10 ^–5 S cm ^–1_，PNG = 28.6 wt％）与一种PTG电解质（1.11×10 ^–4）相当S cm ^–1）。PNG-PTG-PNG电解质的Li ⁺电导率与由微相分离成软PTG和硬PNG域形成的有效Li ⁺传输通道密切相关。
