  1. 1. Machine Learning Implementation for Curing Carbon Fibers using Microwave Technology

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Srivijay Manjunath; [2021]
    Keywords : ;

    Abstract : Curing of carbon fibers using microwave technologies was shown to improve ove rprocesses based on thermal heating, both by reducing time and energy cost. However, realization of the full potential of the approach is hampered by the non-even distribution of the energy during curing. READ MORE

  2. 2. Corrosion protection of aluminum coated with a polymer matrix in presence and absence of conductive polymer

    University essay from KTH/Ytbehandlingsteknik

    Author : Mohamed Hassan Abdi; [2021]
    Keywords : Corrosion protection; Barrier coating; Conductive polymer; Electrochemical impedance spectroscopy; Atomic force microscopy; Korrosionsskydd; Barriär beläggning; Ledande polymer; Elektrokemisk impedans spektroskopi; Atomkraftmikroskopi;

    Abstract : Aluminium och aluminiumlegeringar har ganska bra korrosionsbeständighet, men dessa material kan fortfarande korrodera. Metallkorrosion är aldrig önskvärt och det kan leda till katastrofala resultat i olika branscher och applikationer. READ MORE

  3. 3. Design and conceptual implementation of an improved pre-batch polymer handling process

    University essay from Lunds universitet/Industriell Produktion

    Author : Fredrik Olsson; Linus Christensson; [2021]
    Keywords : Lean; Production Improvement; Polymer Handling Process; Prototyping; Technology and Engineering;

    Abstract : This thesis is a collaborative project between the division of Production and Materials Engineering and Trelleborg AB. The aim of the thesis is to analyse the current pre-batch polymer handling process, assess the current process from a Lean perspective, and provide a new handling process which is more effective in terms of capacity, operator time, forklift transportation and traceability.

  4. 4. A photodegradation study of conjugated polymers for organic solar cells by absorption spectroscopy and atomic force microscopy

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johansson André; [2021]
    Keywords : OSC; solar cells; active layer; polymer; degradation;

    Abstract : The effect of light exposure in ambient air on thin films made from an electron acceptor polymer poly{[N,N'-bis(2-octyldodecyl)naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} (N2200), an electron donor polymer Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl] (TQ1) and their blends, has been studied using UV-vis spectroscopy and Atomic Force Microscopy (AFM). For solutions of TQ1, N2200 and blends, the linearity of the Beer-Lambert law for absorption spectroscopy has been verified. READ MORE

  5. 5. Reaction Mechanism between Chitosan and Cerium(VI) Ammonium Nitrate for Production of a Greener Poly(Vinyl Acetate) Adhesive

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Mårten Schollin; [2021]
    Keywords : Chitosan; Poly vinyl acetate ; Cerium IV ammonium nitrate ; Grafting; Reaction mechanism;

    Abstract : Poly(vinyl acetate) (PVAc) has a major application as an indoor wood adhesive. Low water stability is however, one of the greatest drawbacks of PVAc. By grafting PVAc from a chitosan (CS) backbone (CS-graft- PVAc) water stability of adhesive is increased while good mechanical and adhesive properties are retained. READ MORE
