PVA‐Borax (PB) hydrogel is a promising candidate for drug delivery system. Therefore, it is necessary to find the quantitative relationship between drug release rate and network structure of PB hydrogels to predict and control drug release rate. In this work, at first step the optimum ratio ...
A facile environmentally-benign approach has been developed for the preparation of dynamic, multi-responsive and self-healing hydrogels from inexpensive bamboo pulp, poly(vinyl alcohol) (PVA) and borax. The microfibrillated cellulose (MFC) reinforced PVA-borax hydrogels were produced through a one-pot...
天津大学化工学院张建华副教授等通过在聚乙烯醇-硼砂(PVA-borax)弱凝胶体系中原位引发 N -丙烯酰基甘氨酰胺(NAGA)聚合,非常简单高效地构筑了由动态硼酯键和多重氢键交联的双网络水凝胶,实现了水凝胶的力学强度和自修复性能的同步提升。 关键词 双网络凝胶,动态共价键,自修复水凝胶,天津大学化工学院 ...

Poly (vinyl alcohol)-borate (PVA-borate) complexes in dilute aqueous solutions were investigated by dynamic light scattering (DLS). Two relaxation modes obtained, were scattering vector-q 2 dependent and diffusive. The amplitude of slow mode was independent of borax concentration. In the very ...
In this work, recently reported alkyl-aryl asymmetric viologens in polyvinyl alcohol (PVA) – borax gel electrolyte were studied by spectroelectrochemistry and compared with their corresponding dialkyl and diaryl symmetric viologens. The simultaneous use of cyclic voltammetry, ESR and UV–vis–NIR ...
