    • 摘要: 目的:探讨基于ICF框架下,应用PEO模式设计治疗性作业活动对脑卒中患者康复临床效果的影响。方法:本研究共选取脑卒中患者共60例,采用单盲随机分为对照组和治疗组各30例。2组均接受治疗性作业活动训练,治疗组在常规康复治疗基础上增加ICF框架下PEO模式治疗性作业活动训练。2组患者于治疗前、治疗4周后采用改良Barthel指数(MBI)、加拿大作业活动行为评估(COPM)训练进行评定。结果:治疗组患者治疗后MBI指数及COPM表现分及满意度显著优于对照组(P0.05)。结论:基于ICF框架下应用PEO模式设计治疗性作业活动能明显提升患者的基础性日常生活活动能力(BADL),有利于提高患者对日常生活能力(BADL)和生活满意度。

    • 摘要: Poly(ethylene) oxide(PEO)-based electrolytes have been widely studied for solid-state lithium batteries while their ionic conductivity and lithium-ion transference number still need to be further improved.Herein, using the combined experimental and theoretical approach, we demonstrate a novel, solidstate PEO-deep eutectic solvent(DES) electrolyte for the first time. We found that the in situ formation of DES can reduce the crystallinity of PEO matrix and more Li+ions can move freely owing to the weakened coordination between ether oxygens and Li-ions. Besides, we show that more Li+ions can be dissociated from Li salts in PEO-DES electrolyte using the molecular dynamics simulations. Such liquid-free PEO-DES electrolytes showed good ionic conductivity(2.1 × 10^(-4) S cm^(-1)) which is 160% higher than that of conventional PEO-Li TFSI(8.1 × 10^(-5) S cm^(-1)) electrolyte at 60 °C. Additionally, the PEO-DES electrolyte showed 136% increase of Li-ion transference number(0.33) compared with ionic liquid-doped PEO-Li TFSI(0.14) at 60 °C. Moreover, the PEO-DES exhibited good compatibility with Li metal and stable Li plating/stripping behavior with little morphology change of Li metal. This research also provides new insights into the enhancement mechanisms of novel polymer electrolytes, improving our fundamental understanding of critical challenges that have impeded the adoption of solid-state lithium metal batteries.

    • 摘要: Poly(ethylene oxide)(PEO)-based solid polymer electrolyte is always the most promising candidate for preparing thinner, lighter and safer lithium-ion batteries. However, the lithium dendrites growth of lithium anode and the high-voltage oxidation of cathode are easy to cause the PEO-based battery failure.The way to deal with the different challenges on both sides of the anode and cathode is pursued all the time. In this study, we reported a new strategy to construct the PVDF/PEO/PVDF three-layer structure for solid polymer electrolyte(marked as PVDF@PEO) using PVDF as the functional “skin”. The PVDF@PEO electrolyte can effectively prevent from the lithium dendrites, and shows a stable cycling life over1000 h in the Li/PVDF@PEO/Li cell. In addition, the PVDF@PEO electrolyte exhibits higher oxidation resistance and can be matched with high-voltage LiCoO_(2) cathode. The Li/PVDF@PEO/LiCoO_(2) cell delivered a specific capacity of about 150 m Ah g^(-1) over 150 cycles and maintained good cycling stability. Our research provides insights that the polymer electrolytes constructed with PVDF functional “skin” can simultaneously meet the challenges of both anode and cathode in solid-state lithium-ion batteries(SSLIBs).

    • 摘要: 深入研究表面活性剂和高分子聚合物复合水溶液减阻规律和流变特性,有助于理解复合减阻机理促进其在工程领域的应用。利用旋转圆盘减阻装置研究了温度、浓度和雷诺数对表面活性剂(CTAC/NaSal)、高分子聚合物(PEO)及其复合水溶液减阻率的影响;同时利用旋转流变仪研究了浓度、温度和剪切速率对三种减阻溶液表观黏度的影响。研究表明,PEO和CTAC/NaSal复合溶液的减阻率明显高于纯水溶液的减阻率,复合溶液具有减阻雷诺数和减阻温度范围宽及减阻率高的特点,且PEO浓度变化对复合溶液减阻率的影响小于CTAC/NaSal浓度变化的影响;在所测温度和雷诺数范围内,相同剪切速率下复合溶液的表观黏度基本高于纯溶液的,一些浓度组合的复合溶液在较低剪切速率和较高剪切速率下均出现剪切增稠现象,温度升高使复合溶液剪切增稠现象推迟、次数减小以及表观黏度峰值降低。

    • 摘要: 为提高正渗透膜的抗污染性能,以O,O'-二(2-氨基丙基)聚丙二醇-嵌段-聚乙二醇-嵌段-聚丙二醇和均苯三甲酰氯(TMC)为水相、油相反应单体在聚砜基膜上进行界面聚合,制备聚环氧乙烷(PEO)亲水型聚酰胺正渗透膜(PSf-Jeff/TMC复合膜),采用红外光谱、X光电子能谱和水接触角等手段研究选择分离层的化学结构和亲水性能,考察界面聚合时间、反应单体浓度和后处理温度等制备条件对正渗透膜渗透分离性能的影响,并以牛血清蛋白作为污染物分析其抗污染性能.结果表明:聚合时间30 s、TMC质量浓度1.5 mg/mL、水相单体质量分数3%、热处理温度为60°C时所制备的PSf-Jeff/TMC正渗透膜,在1 mol/L氯化钠、室温条件下测得水通量1.75 L/(m2·h),反向盐通量140 g/(m2·h);与间苯二胺复合膜PSf-MPD/TMC相比,PSf-Jeff/TMC复合膜接触角更小,亲水性能更好,具有一定的抗污染性能,通量恢复率达到91.4%.%In order to improve the antifouling property of forward osmosis membrane, O'O-bis(2-aminopropyl) polypropy-lene glycol-block-polyethylene glycol-block-polypropylene glycol and trimesoyl chloride(TMC) were utilized as the reactant of aqueous monomer and oil phase monomer respectively to fabricate the hydrophilic PEO polyamide forward osmosis membrane (PSf-Jeff/TMC composite membrane) through the interfacial polymerization on the polysulfone support membrane. The chemical structure and hydrophilic performance of PEO-functionalized se-lective layer were evaluated by total reflection Fourier transform infrared spectroscopy (FTIR-ATR), X-ray photoelectron spectroscopy (XPS) and water contact angle technique. The effects of preparation parameters in-cluding polymerization time, concentration of the reactive monomer, and heat-treatment temperature on the per-meation and separation performance of the forward osmosis membrane were investigated and the antifouling per-formance of the forward osmosis membrane was analyzed by using BSA as pollutant. The results show that the op-timum preparation conditions are as follows: the reaction time is 30 s, the concentration of aqueous phase monomer is 3%(mass fraction), the mass concentration of TMC is 1.5 mg/mL, and the curing temperature is 60°C. The PSf-Jeff/TMC composite membrane has a pure water flux of 1.75 L/(m2·h)and reverse salt flux of 140 g/(m2·h)under the condition of 1 mol/L NaCl at the room temperature. The PSf-Jeff/TMC composite membrane has better hydrophilicity with a lower water contact angle,and an excellent antifouling property with pure water flux recovery of 91.4%compared with PSf-MPD/TMC composite membrane.
