【摘要】：借助引發(fā)劑過(guò)硫酸鉀(KPS)分別將3種Gemini表面活性劑分子(G_(16-2-16)、G_(12-2-12)和G_(8-2-8))聚合成線性高分子聚合物,然后將上述線性聚合物長(zhǎng)鏈"鎖定"在交聯(lián)的季銨化殼聚糖網(wǎng)狀結(jié)構(gòu)中,制備3種半互穿網(wǎng)絡(luò)陰離子交換膜。為了考察疏水長(zhǎng)鏈的長(zhǎng)度對(duì)陰離子膜電導(dǎo)率和機(jī)械性能的影響,對(duì)膜的離子交換量、電導(dǎo)率和機(jī)械性能等特性進(jìn)行考察。結(jié)果表明:疏水鏈越長(zhǎng),越有利于膜內(nèi)部相分離結(jié)構(gòu)的形成,團(tuán)簇效果越明顯,同時(shí)增強(qiáng)了膜結(jié)構(gòu)的機(jī)械性能。當(dāng)烷基鏈長(zhǎng)度由8個(gè)碳增至16個(gè)碳,膜拉伸強(qiáng)度由17.22MPa增加到20.08MPa,70℃下,電導(dǎo)率由(4.11×10~(-2))S/cm增加到(5.00×10~(-2))S/cm。
[Abstract]:By means of the initiator potassium persulfate (KPS), three kinds of Gemini surfactants were polymerized into linear polymers, respectively, by polymerizing three kinds of Gemini surfactants (Gill 16-2-16) and GSP 8-2-8), and then the linear polymer chains were "locked" in the cross-linked quaternary ammonium chitosan network. Three kinds of semi-interpenetrating network anion exchange membranes were prepared. In order to investigate the effect of the length of hydrophobic long chain on the conductivity and mechanical properties of anionic membrane, the ion exchange capacity, conductivity and mechanical properties of the membrane were investigated. The results show that the longer the hydrophobic chain is, the more favorable the formation of the phase separation structure is, the more obvious the cluster effect is, and the more the mechanical properties of the membrane structure are enhanced. When the length of alkyl chain was increased from 8 carbon to 16 carbon, the tensile strength of the film was increased from 17.22MPa to 20.08 MPA ~ (-1) 鈩，
