Recent progress on nanofiber membranes for contribution to sustainable society was demonstrated in the present review. An all bio-based polymer composite consisting of electrospun poly(L-lactic acid) (PLLA) ultrafine fibers and network polymers of epoxidized soybean oil was fabricated. The PLLA ultrafine fiber non-woven mat was enzymatically degraded significantly faster than the PLLA film, which suggests the new evaluation method of biodegradability of polymers to shorten the test period by using electrospun ultrafine fibers. By immobilization of enzymatically synthesized phenolic polymers on electrospun ultrafine fibers, an anti-allergen sheet was developed. Unusual shape change of electrospun fiber mats of acrylic resin was observed by immersion in an aqueous ethanol, which was applied for fabrication of a porous material of acrylic resin by phase separation. Three-dimensional fibrous matrix was fabricated by dry spinning using a coaxial nozzle and ethanol bath collector.
