Advanced polymeric materials undoubtedly constitute one of the most promising classes of new materials due to their intriguing electronic, optical, and redox properties. The incredible progress in this area has been driven by the development of novel synthetic procedures owing to the emergence of nanotechnology and by the large array of applications. In particular, hybridization of polymeric materials with nanomaterials has allowed the production of promising functional materials with tailored properties and functionalities for targeted biomedical applications. Consequently, sufficient researchers have carried out imperative studies on these advanced polymeric materials over the last decade. Beyond scientific and fundamental interest, such advanced materials are conspicuous from technological perspectives as well. In this review, we accentuate the proliferation of advanced polymeric materials in diverse biomedical applications.
ABSTRACT:In this work, we present an exhaustive study on the effect of a cosolvent addition pathway on the optical, structural, and morphological characteristics of poly(3-hexyl thiophene) (P3HT): [6, 6]-phenyl C 61 -butyric acid methyl ester (PCBM) composite films. Our recommended pathway of cosolvent addition has shown to benefit the composite film by forming more crystallized and ordered P3HT polymer domains on the film surface as revealed by the UV-vis absorption, grazing incidence X-ray diffraction (GI-XRD), and atomic force microscopy measurements. GI-XRD measurements that were carried out at three grazing incidence angles (0.11 ο , 0.13 ο , and 0.3 ο ) also substantiate a more prominent upright concentration gradient of the film processed through the modified method. The contact angle measurement reveals accumulation of more P3HT crystallites at the surface of co-solvent modified films. A highly quenched photoluminescence signal precise phase separation between the blended components of the modified film, promoting exciton dissociation at the donor-acceptor interfaces during photoinduced excitations.
