Beadless bionanofibers were developed from blends containing 30 wt% and 40 wt% Chlorella vulgaris with 10 wt% zein powder (CV30 and CV40) via electrospinning. Thinner nanofibers were obtained from the CV30 blend (409.9 ± 130.7 nm) than from the CV40 blend (430.4 ± 148.6 nm). Brunauer–Emmett–Teller calculations revealed a higher porosity and a larger surface area for the CV40 nanofibers. Various binding mechanisms involving ester and carbonyl groups, π-π stacking, and π-anion interactions were discussed when the bioactive compounds from Chlorella vulgaris interacted with zein molecules. Higher DPPH radical scavenging activity (RSA) and ABTS reduction were observed for CV30 nanofibers compared to CV40 nanofibers at all tested concentrations. p-Coumaric acid (91.19–92.00 μg/mg) and ferulic acid (63.09–63.16 μg/mg) exhibited the highest concents among the polyphenols in the nanofibers. Compared with the powder, nanofibers had higher temperatures of maximum degradation, demonsantrating improved thermal performance. Covalent and peptide bonds broke above 250 °C. The transition zone temperature range 250–300 °C between Chlorella-zein was correspond to the interface between adjacent hydrogen-bonded molecular sheets. The specific interactions between Chlorella and zein lead to alterations in the crystalline phase and regions. Changes in two-theta intensities were attributed to hydrogen bonding between zein hydroxyl groups and Chlorella carboxyl or hydroxyl groups. Compherensive characterization revealed the synergistic potential of Chlorella-zein nanofibers as biomaterials and their potential applications in the development of reusable packaging, smart coatings, and self-cleaning surfaces.
