“…Corona discharges and flame treatments are known to produce mostly C-O bonds (e.g., Refs. 4,37,64), with smaller amounts of carbonyls and still lower levels of carboxyls. Only low-levels of peroxydes are reported from corona discharge-treated polyethylene.…”

Advancing and receding contact angles below 5 • have been obtained on PMMA surfaces with the implantation of argon and oxygen ions. The ion implantations were performed by means of the Immersion Plasma Ion Implantation (IPII) technique, a hybrid between ion beams and immersion plasmas. Characterization of treated PMMA surfaces by means of XPS and its combination with chemical derivatization (CD-XPS) have revealed the depletion of oxygen and the creation of dangling bonds, together with the formation of new chemical functions such as -OOH, -COOH and C=C. These observations provide a good explanation for the strong increase of the wetting properties of the PMMA surfaces.

The oxidation of polypropylene (PP) homopolymer in air was performed using dodecanol-1 as an accelerator. The experiments were conducted under atmospheric pressure at 180-220 o C. Spectroscopic data indicated the formation of polar groups such as ketones, esters, alcohols, anhydrides etc. as determined by FTIR and ESCA. The scanning electron microscopy (SEM) showed the variations of morphology of the oxidation products. The fusion temperatures were determined by differential scanning calorimetry (DSC). The variations of solubility of PPO as compared with the original PP were investigated in solvents such as MEK, THF, and toluene.Surface tension and molecular weights were determined by tensiometry and gel premeation chromatography (GPC). The melt flow index (MFI) of different samples were determined.

“…Surface of coal will be heterogeneous depending on the distribution of these moieties on the surface and this heterogeneous nature of its surface is an important property affecting all reactions at the coal interface. It should be pointed out that only minor changes in surface properties are adequate to affect surface phased phenomena [2][3][4]. In the case of heterogeneous material like coal, knowledge of average properties 'presented at the 118th annual AIME meeting at Las Vegas, Feb28, 1989. would not provide sufficient information to control interfacial properties.…”

Understanding the nature of coal surface heterogeneity is a prerequisite to accurate characterization and efficient control of coal surfaces. A new approach based on film flotation has led to estimation of surface energy distributions in individual coal particles. Changes in the distribution of surface sites due to oxidation and polyacrylamide adsorption on coal is studied here using the above approach. New information on possible conformations of adsorbed polymers is also obtained.
