transfer (RAFT) yielded well-defined polymers, PQuiBoc, of controllable molar masses (6 and 12 kg mol−1) with low dispersities (Đ, Mw/Mn < 1.3). Protected (PQuiBoc) and deprotected (PQuiOH) derivatives of the polymer exhibited a high zinc-binding capacity, as determined by semi-quantitative SEM/EDXA analyses, allowing the electrospinning of microfibres from a PQuiBoc/polystyrene (PS) blend without the
与金属结合的聚合物纤维在废水中的金属螯合膜,无纺布伤口敷料,光催化基质等的各种应用中引起了广泛的关注。本文报道了基于8-羟基喹啉的锌结合苯乙烯单体QuiBoc的设计与合成。随后通过可逆加成-断裂链转移(RAFT)聚合产生了可控制的摩尔质量(6和12 kg mol -1),分散度低(Đ,M w / M n)的明确定义的聚合物PQuiBoc<1.3)。通过半定量SEM / EDXA分析确定,该聚合物的受保护(PQuiBoc)和脱保护(PQuiOH)衍生物显示出高的锌结合能力,从而可以将PQuiBoc /聚苯乙烯(PS)混合物中的微纤维电纺丝去除保护基。将纤维毡简单地“浸涂”到ZnO悬浮液中,表明仅PQuiBoc含量为20%的PQuiBoc / PS超细纤维比纯PS超细纤维(11%)具有几乎高三倍的ZnO负载量(29%)。
