The Young's modulus and hardness of the materials were examined using a Nano Indenter XP, MTS with a Berkovich tip (20 nm) creating random points of indentations. Nano-indentation was performed in CSM tip calibration mode, with a strain of 0.05 s−1, depth of 1000 nm and strain rate of 10 nm s−1. The Brunauer–Emmett–Teller (BET) method was used for physical characterization to measure the surface area and pore volume of the PC and TCP materials by adsorption–desorption isotherms using nitrogen gas at 77 K (NOVA 3200e, Quantachrome Instruments). The viscosity and conductivity of the polymeric solution were measured using a viscometer (VR 3000 model L, Viscotech Hispania S.L., Spain) operating at 50 rpm and an L3 probe at 25 °C and a conductivity meter, respectively.

The prepared microplastics were characterized by attenuated total reflectance (ATR)-Fourier transform spectroscopy (FTIR) (FT/ IR-4100 Jasco Inc., Tokyo, Japan), scanning electron photomicrography (SEM) (S-4800 Hitachi, Tokyo, Japan), N 2 -BET methods using a surface area and porosimetry analyzer (Nova 3200e, Quantachrome Instruments, Boynton Beach, FL) for identification of the component polymers, surface micro-morphology, specific surface area and pore volume of the particles, respectively. The carbon contents of the microplastic particles were analyzed using an elemental analyzer (Vario Micro, Elementar Analysensysteme GmbH, Lagenselbold, Germany). The point of zero charge (PZC) was measured using potentiometric titration (ZDJ-4A, Inesa Instruments, Shanghai, China).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
