An effective method to optimise plasma immersion ion implantation: Sensitivity analysis and design based on low‐density polyethylene

Abstract The performance of polymer surface treatment using plasma immersion ion implantation (PIII) depends on many operating parameters, such as duration, radiofrequency power, pulsed bias voltage and pulse repetition rate, the fluence applied surface. Currently, identification optimal parameters to achieve specific targets is heavily based trail error with extensive experimental testing. Herein, we present an optimisation method sensitivity analysis polynomial chaos expansion design Kriging surrogate model greatly reduce amount experiments. combined effects PIII low‐density polyethylene modifications are investigated, demonstrating validation effectiveness design. new approach offers highly accurate computationally efficient way for achieving optimum radical density, wettability optical transmittance that important biomedical applications.
