Fabrication and Surface Properties of Hydrolyticly Function-switchable Polymer Brush
Bibliographic record
Abstract
A hydrolysable cationic polycarboxybetaine ester polymer brush( PCBMA-1C2) was fabricated by photografting method with surface-coupled tertiary amine as hetergenous hydrogen donor and benzophenone( BP) as photosensitizer. The hydrolysis of PCBMA-1C2 modified surface was evaluated by studying the hydrolysis behavior of CBMA-1C2 monomer under different ammonium hydroxide concentrations. X-ray photoelectron spectroscopy( XPS) and water contact angle were used to monitor the chemical changes and hydrophilicity,respectively. The protein adsorption and platelet adhesion experiments were used to evaluate the interaction between the material surface and the biomolecules. The results show that when the concentrations of ammonium hydroxide are 0. 1,0. 2,0. 3 and 0. 4 mol / L,the degrees of hydrolysis( DH) of terminal ester of CBMA-1C2 monomer are 6%,43%,56% and almost 100%, respectively. Compared with Glass-PCBMA-1C2 surface,with the increase of DH,the protein adsorption of BSA are reduced by 3%, 76%,93% and 96%,and that of Fg are reduced by 11%,45%,90% and 96%,respectively. When DH 50%,the hydrolyzed Glass-PCBMA-1C2 surface exhibits good resistance of protein adsorption and platelet adhesion.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
