Optics Fundamentals of Polymer
Interaksional Light- Matter ion Polymers
Optikal realties arise fromm how polymer interact with electromagnetic radiation. Key paramaters includde de de de:
- FLT: 0 = 333; Refactie index (n):
- FLT: 0 = 33I; Transparency and absorce insertion: FI1; FLT: 1: 1 AG3; Governed by br 's electronic strucre. Absorbance peak recorecd to electronic transitionos (UV-Vis) or vibrationaI overtoneR.
- Pertama, FLT: 0 = 0 = 33; Birefringence: 1f 1; FLT: 1 1f 3; Anisotropy in refactile index menyebabkan orientaon of polymer chains.
- FLT: 0 = 033. Foto-foto pertama kali muncul: FLT: FLT: 1: 1 FLT:
- FLT: 0 FLT; STAT3; Scatterin: STA1; FLT: 1 FLT: 1 FL3; Caused by density fluktuasi, crystalitites, or phase- separated domains. Minimizing scattering is critsar for waveguide and lenses.
