Review of Polymer Surface Modification Method

This paper reviewed a variety of methods of polymer surface modification, which mainly includes Solution processing method, Plasma treatment，Surface grafting method，Irradiation treatment and method of Atomic force microscopy probe shock , and the specific polymer material combined with the modification method and its modification mechanism was introduced in detail.Polymer has very extensive application both in chemical fields and in daily life, but due to its poor surface hydrophilicity and wear resistance, the further application of polymer materials were limited. In order to improve its surface properties, modification are needed on the surface of the polymer. Polymer surface modification means to operate on the surface of polymer within the scope of nanometer level, and give some new properties on material surface, such as hydrophilicity, scratch resistance, under the premise of without affecting the material ontic properties.There are many methods of polymer surface modification. This paper reviewed Solution processing method, Plasma treatment，Surface grafting method，Irradiation treatment and method of Atomic force microscopy probe shock . Different methods of modification combined with specific materials are introduced as follow.

Pdms Molding

We present and compare two processes for plasma-based surface modification of Polydimethylsiloxane (PDMS) to achieve the antisticking behavior needed for PDMS-PDMS molding. The studied processes were oxygen plasma activation for vapor phase silanization and plasma polymerization with tetrafluoromethane/hydrogen mixtures under different processing conditions. We analyzed topography changes of the treated surfaces by atomic force microscopy and contact angle measurements. Plasma treatment were conducted in a parallel plate reactive ion etching reactor at a pressure of 300 mTorr, 30 Watts of RF power and a total flow rate of 30 sccm of a gas mixture. We found for both processes that short, low power, treatments are better to create long-term modifications of the chemistry of the polymer surface while longer processes or thicker films tend to degrade faster with the use leaving rough surfaces with higher adherence to the molded material.

Contact Angle Measurements

<p>Nanostructured wrinkles were developed on fully bio-based poly(trimethylene furanoate) (PTF) films by using the technique of Laser Induced Periodic Surface Structures (LIPSS). We investigated the effect of irradiation time on wrinkle formation using an UV pulsed laser source, at a fluence of 8 mJ/cm2. It was found that the pulse range between 600 and 4800 pulses allowed formation of periodic nanometric ripples. The nanostructured surface was studied using a combined macro- and nanoscale approach. We evaluated possible physicochemical changes taking place on the polymer surface after irradiation by infrared spectroscopy, contact angle measurements and atomic force microscopy. The macroscopic physicochemical properties of PTF showed almost no changes after nanostructure formation, differently from the results previously found for the terephthalic counterparts, as poly(ethyleneterephthalate), PET, and poly(trimethyleneterephthalate), PTT. The surface mechanical properties of the nanostructured PTF were found to be improved, as evidenced by nanomechanical force spectroscopy measurements. In particular, an increased Young’s modulus and higher stiffness for the nanostructured sample were measured. <br></p>
