Bacterial Cellulose and Silica Hybrid Reinforcements in Poly-(vinylidene fluoride) Composite Membranes

Poly(vinylidene fluoride)-based ion-track membranes with asymmetrical pores

We have been working on ion-track membranes of poly(vinylidene fluoride) (PVDF) because they have attracted a renewed interest for their applications to fuelcells [1]. There were two main conclusions: (i) The PVDF ion-track membranes can efficiently be prepared under milder etching conditions, i.e., without any oxidant additives in the alkaline etching solution [2]; and (ii) irradiation with io...

High-sensitivity ion track-etching of poly(vinylidene fluoride) membranes

Quite recently, ion-track membranes of poly(vinylidene fluoride) (PVDF) have attracted a renewed interest for their applications to next-generation electrochemical devices such as fuel cells [1,2]. In order to produce tracketched pores in PVDF films, several kinds of etching solutions were previously employed. In most cases [3], a highly concentrated aqueous KOH solution with a KMnO4 additive w...

Bacterial cellulose membranes and spheres composite with poly (l-lactic acid) through in situ polymerization

Background Since poly(L-lactic acid) (PLLA) shows great biocompatibility as well as biodegradability [1] and bacterial cellulose (BC) is a high purity biomaterial with unique structural and mechanical properties, composed of cellulose and water [2,3], both are biopolymers with great potential for biomedical applications. This work had the purpose of producing biocomposites with properties that ...
