The main blow spun polymer systems: processing conditions and applications

This review aims at providing an examination of the central polymeric systems that have been tested by the Solution Blow Spinning Technique (SBS). The SBS is an on-demand micro/nanofibrous material forming technique that uses simple instrumentation, thus making its research substantial. Although other studies had already presented the SBS parameters and their correlations with fiber morphology, it's still unclear for polymeric researchers which systems have already been tested, therefore some questions remain unanswered, such as: which polymers have been used most in the art?, which solvents have promoted the fiber formation?, which additives or particles were tested for composite polymer fibers?, for which applications have the fibers been targeted?, what adaptations have been investigated to overcome the challenges of the process?. Seventy-nine articles related to polymeric fibers produced by SBS, reported from January 2010 to May 2019, were chosen among four databases, using precise keywords. The principal findings of these articles were presented and reviewed, using additional references as support. From this study, polymeric researchers will have access to the current SBS state-of-the-art, being able to try new polymer-solvents combinations, as well as to solve the existing process inconveniences.
