Enhancing Interfacial Bonding of a Biodegradable Calcium Polyphosphate/Polyvinyl-urethane Carbonate Interpenetrating Phase Composite for Load Bearing Fracture Fixation Applications
Bibliographic record
Abstract
This thesis describe methods to improve the interfacial stability of an interpenetrating\nphase composite (IPC) polyvinylurethanecarbonate), and to increase the hydrophobicity of the polymer phase. The\ncurrent IPCs introduce covalent bonding between the phases via silanizing agents to enhance the interfacial stability. Incorporation of the silanizing agents was also intended to reduce the IPC’s sensitivity to interfacial hydration, thereby enhancing the IPC’s resistance to degradation during aging. Lysine diisocyanate was used to increase the\nhydrophobic character in the polyvinylurethanecarbonate resin. The polymer resins were infiltrated into porous CPP blocks with 25 volume% interconnected porosity and polymerized to produce the IPCs. After mechanical testing following a aging study it was found that the silanizing agents contributed to stability of the mechanical properties under aqueous conditions. It was concluded that the mechanical properties and stability were comparable to available biodegradable composites, as well as being biocompatible to a preosteoblast model cell line.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
