Fabrication and Characterization of Novel Poly(d-Lactic Acid) Nanocomposite Membrane for Water Filtration Purpose

The development of membrane technology from biopolymer for water filtration has received a great deal attention researchers and scientists, owing to the growing awareness environmental protection. present investigation is aimed at producing poly(D-lactic acid) (PDLA) membranes, incorporated with nanocrystalline cellulose (NCC) nanowhisker (CNW) different loadings 1 wt.% (PDNC-I, PDNW-I) 2 (PDNC-II PDNW-II). From morphological characterization, it was evident that nanocellulose particles induced pore formation within structure membrane. Furthermore, greater surface reactivity CNW facilitates in enhancing wettability membranes due increased hydrophilicity. In addition, both thermal mechanical properties all filled under demonstrated significant improvement, particularly PDNW-I-based which showed improvement aspects. PDNW-I presented permeability 41.92 L/m2h, when applied pressure range 0.1–0.5 MPa. clearly demonstrates CNWs-filled PDLA fabricated this have very high potential be utilized purpose future.
