“…This treatment has been known as CASING (cross-linkage by activated species of inert gases) [13,14]. The plasma analysis ( Figure 2) indicates that with increase in the microwave power the ion density also increases whereas the plasma potential decreases with the increase in the microwave power.…”

Polystyrene (PS) and polyethylene (PE) samples were treated with argon and oxygen plasmas. Microwave Electron Cyclotron Resonance (ECR) was used to generate the argon and oxygen plasmas and these plasmas were used to modify the surface of the polymers. The samples were processed at different microwave powers and treatment time and the surface modification of the polymer was evaluated by measuring the water contact angle of the samples before and after the modification. Decrease in the contact angle was observed with the increase in the microwave power for both polystyrene and polyethylene. Plasma parameters were assessed using Langmuir probe measurements.Fourier transform infrared spectroscopy showed the evidence for the induction of oxygen based functional groups in both polyethylene and polystyrene when treated with the oxygen plasma. Argon treatment of the polymers showed improvement in the wettability which is attributed to the process called as CASING, on the other hand the oxygen plasma treatment of the polymers showed surface functionalization. Correlation between the plasma parameters and the surface modification of the polymer is also discussed * Corresponding author: gmrao@isu.iisc.ernet.in

The influence of different types of low and atmospheric pressure plasma on poly(ethylene terephthalate) (PET) has been studied in terms of changes in molar mass and molar mass distribution. Apart from a variation of plasma gases (oxygen, helium) different types of plasma (microwave, radio frequency, corona discharge) were used for the plasma surface modification. The changes in molar mass and types of functional end groups of lower molar mass products were investigated by means of matrix‐assisted laser desorption/ionization time of flight mass spectrometry (MALDI‐TOFMS), whereas the high‐molar mass fraction was analyzed by means of size‐exclusion chromatography (SEC). The formation of crosslinked products during exposure to a helium plasma, which emits preponderately energy‐rich and intense ultraviolet radiation, was proved by means of thermal field‐flow fractionation (ThFFF). This method combined with a multiangle laser light scattering (MALLS) detector allows detection of weakly crosslinked polymers and microgels. © 1998 John Wiley & Sons, Inc.
